Would you be able to provide a link to the $10 bluetooth adapter? I did some looking at the link provided in google play store app and it listed adapters in a very wide range of prices.

Edit: Link to the one I am getting

u/th1341 · 491 pointsr/Showerthoughts

I have 2 of them. 10 dollars each

Edit: I can't find the $10 ones I have but here is one for $20

Edit: obligatory Thank you kind stranger for giving me gold!

u/IMLOwl · 127 pointsr/AdviceAnimals

Get one of these, plug it into your car in the port hidden under your steering wheel, download app called Torque, get error code, google error code, see if it's something you can fix yourself (often it is).

Edit: These only work on Android. You can buy dedicated units (also cheap) or you can buy an iOS version that costs 4x as much. Similarly cheap priced models claim to work on iOS, but I have yet to see anyone actually get one of them to work.

u/adamhaeder · 114 pointsr/gadgets

I thought this would qualify, but I misremembered the price, it's $23.99, but it's the best I could do

BAFX Products (TM) - PIC18F2480 Bluetooth OBD2 scan tool - For check engine light and other diagnostics - Android compatible

u/SlateRaven · 72 pointsr/LifeProTips

Yes - I bought a cheap $15 bluetooth ODB2 module that links to my phone. From there, I use Torque to manage everything. Great for testing sensors, checking codes, etc... Also cool to have it in my glovebox for when my coworkers need one out of the blue - makes you look cool for half a second.

EDIT: Here is what I use for the module:

As for the app, I use Torque Pro:

u/10leej · 46 pointsr/povertyfinance

Just so you know there are much cheaper alternatives to the Bluedriver. I personally use this one and it provides all the same stuff the Bluedriver provides for 1/5 the cost so you only have to work an hour and a half.

u/Coomb · 46 pointsr/gadgets

Why would you pay $75 for an OBDII scanner when you can buy the same thing on Amazon for $24?

u/TrooperThorn · 45 pointsr/privacy

Even if your vehicle is not fitted with OnStar and even if you have replaced the stereo, GM still reports Latitude and Longitude data to the ECU.

Buying an ECU Scanner can report all of the data, then use an app like Torque to see what is tracked by the system.

u/somerandomguy02 · 44 pointsr/TalesFromTheSquadCar

Not that you'd have the time to fix it yourself(or even be allowed to) but if you're curious you can get an ELM 327 ODB Bluetooth code reader for like $20.

This is the one I got. It's a true ELM 327 reader and not some Chinese reverse engineered hacked together crap. I keep it plugged into my ODB reader all the time.

The reason these are so cheap compared to a professional shop reader is because the reader is just an interface and knows how to talk to the computer. It just "translates" and passes stuff along to your phone/tablet which does the real heavy lifting. Torque Pro or Forscan(for Ford/Mazda) apps on your phone. You'd at least be able to see "oh shit, low oil pressure" or "shit water temps are through the roof, that's why it wont go above 95" so I'm about to be sitting on the side of the road for an hour. Or if it's just like some random dead O2 sensor or an occasional misfire on a cylinder or some vacuum leak that's making it run weird. You'd at least have some peace of mind.

u/MyNameIsRay · 32 pointsr/LifeProTips

Or spend $20 on an OBDII scanner that pairs to your phone, with a free app to read the codes.

This way, anything 1996 or newer (except for some exotic cars) can be read without having to jump on one foot backwards while humming the star spangled banner and cycling the ignition 5 times.

u/PinkyandzeBrain · 32 pointsr/Showerthoughts

Here's one you can buy on Amazon that hooks to your Android via Bluetooth - Bluetooth OBDII Scan Tool for Android Devices

u/chrisbrl88 · 32 pointsr/MechanicAdvice

Here's your device, here's your app, here's your how-to.

EDIT - I wanna add: I didn't make that how-to. That's not me. However, it worked for me.

u/32F492R0C273K · 24 pointsr/BlackPeopleTwitter

Got this one for $12 and it works great with Torque and other apps on Android.

u/lakeplacidd · 24 pointsr/Android

There are already apps available that link via Bluetooth to a ODB2 sensor that will diagnose your vehicles. The sensors are really cheap and can be found on sites like amazon:

u/CDimmitt · 22 pointsr/starterpacks

Also, check this little guy out. If your car is model year 1996 or newer, it should have an onboard diagnostic port- usually located underneath the steering wheel in the foot well. Plug that scanner into it and pair it to your phone via bluetooth and you can read the fault codes that caused your check engine light. It eliminates A LOT of worry or guesswork.

u/NightGod · 22 pointsr/Showerthoughts

Is the one I usually see recommended. Cheaper ones are flaky, more expensive ones are a waste of money.

    And, of course, jumper cables, a poncho or two, some spare water bottles and all that good stuff that stays in the truck too.

    Edit: Honestly, this is a great place to start--Stanley 65-Piece Homeowner's Tool Kit

u/stonewall1979 · 17 pointsr/MechanicAdvice

I'm just a tinker too, but if he doesn't have a scan tool to reader error codes, look at the new Bluetooth sets. Plug in to the OBD2 port and download the app to you phone. Get all the codes and internet research in one, plus see engine manager info on some models.

They're not expense and are available on Amazon. This is similar the one I have. and there are a lot of options out there.

u/Daddy007FTW · 15 pointsr/LifeProTips

Screw that Groupon one. Here's one from Amazon that is the same price all the time and is better. I ordered one and can't be more pleased. Read the reviews and answered questions on Amazon for some great tips, including how to reset the check engine light.

u/Manhattan_Flapjack · 15 pointsr/FiestaST

It cost me around $50-$60 I think. I used this camera and I used this OBD2 adapter. I also needed some small connectors to plug the video wire into the back of the head unit (these things).

I used this thread by /u/brbauer2 as a guide, which was very helpful.

It was kind of difficult, but mostly because I don't really have much experience with the wiring stuff so I went slow to make sure I didn't mess up any splices or anything. I also initially put the wrong wire into the back of the head unit, so I had to take it back apart and use the right wire (the thread I used shows a red wire in the back of the head unit connector, its actually the yellow wire from the video cable that you want) but that only took maybe an additional 30 minutes.

Overall, I'd say go for it if you're interested!

u/grnmtboy · 14 pointsr/Volkswagen
u/transcendent · 14 pointsr/AdviceAnimals

Bluetooth versions generally work with Android phones. They will not work with iPhones, however.

I bought one of these that works fairly well with an old Galaxy SII phone. I use the torque app to read live info and codes:

u/BICEP2 · 14 pointsr/motorcycles

On a related note, for anyone looking to do this with a car you can buy cheap bluetooth OBD2 modules on Amazon for about $25.

On Android most people use the app Torque.

I use the $5 paid version of torque, I don't remember what the limitations are for the free version of it but it's money well spent because you can view a lot of diag data, check engine codes etc.

There are a couple times where I connected it to peoples cars, texted them the CEL codes, and cleared the light for them when its something simple. It was money well spent.

u/OreoDragon · 14 pointsr/funny

A lot of places will try to charge you like $40 for this, even though it takes literally zero expertise or effort. You can get a bluetooth OBD reader for 11ish bucks and any one of a number of free apps for an Android or iPhone to connect to it and read codes, reset the light, etc.

u/HORSEtheGAME · 14 pointsr/cars

How about a diagnostic reader? Something like this. Basically if your car has the engine (or another) light on you can plug that in and your phone will tell you what the problem is. You'll need an app like Torque for it to work.

A dashcam is another gift that is something anyone could benefit from, but not everyone would necessarily think to buy for themselves. Over on /r/dashcam they have some really good guides on what to get. Expect to spend about $100, though. It seems like this one is the best bang for your buck according to their guide.

u/Jowitness · 14 pointsr/AdviceAnimals

Protip 1: a lot of autopart stores will check what the light means for free.

Protip 2: Get this And this and be able to check the lights and reset them yourself along with monitoring a ton of other vehicle functions

u/fatbottomedgirls · 13 pointsr/DIY

For those who aren't aware you just need a bluetooth OBDII dongle to use the Torque/Torque Pro app with any android phone or tablet. For example, lots of folks find that this cheap one works great:

Similar IOS apps require a wifi rather than bluetooth dongle, such as this one:

u/keepthisshit · 13 pointsr/technology

uhh yeah, not sure if you understand how much faster computers are than you at math, but it would take the entire population of mankind to compete with my GPU at mathematics.

it could easily be a OBD RF transmitter. tech already exists. look now i just need to run a real time simulation oh noes! if only we could do that on a phone...

EDIT: for example a $70 GPU does over a trillion floating point operations a second, I doubt you could get 7 billion people to do that. Did i mention it did that with a mere 80 Watts of power...

u/ricothecat3 · 13 pointsr/prius

You have to buy an OBD2 for about $20 from eBay or Amazon and download the “Dr. Prius” app. Then you pay $12 on the Dr. Prius app and you have unlimited scans. The total cost is $32 but it’s yours forever. Check it out on YouTube. Here’s the link for the one I bought.

u/TheLiqourCaptain · 12 pointsr/BMW

50's Kid (Super Awesome):

Shop Life TV (Pretty effen gewd):

Well the people in the forums are the people with the problems, but that's not to say they aren't the most knowledgeable group of people about the e46. But the youngest E46 is 12 years old, so unless it's a garage kept car from an old couple, it'll have to be fixed a little soon into your ownership. You'll be advised to do $300,000 in preventative maintenance when on the forums, don't. I love my car but I only paid $3,000 for mine had I done everything the forum members suggested I would've spent another $3,000 in repairs. Keep up on your plugs and coils. If I'm not mistaken the 328s and 325s have transmissions made by GM and no one cares for them, so wait for a 330. I'm sure I'll get corrected on the transmissions but whatevs enjoy the plethora of links.

A Bosche fuel pump from Amazon is $130 and the gasket is $20.



The exact fuel filter $60:

OEM plugs are $35, again Amazon.

DISA rebuild kit is $80 (DO THIS ONE ASAP, It's the one thing I always tell people, it'll prevent a steel pin from falling into a cylinder and ruining your engine) I bought mine from G.A.S. German Auto Sport I think. I love their warranty, if my DISA fails they'll give me that $80 towards one of their DISA units, like $400

Coolant system:
Expansion tank - $30 (Amazon) - known as the most likely failure

Radiator -$150 (AutoZone)
Lower radiator hose - $30 (Advance)

Temp sensor in lower hose - $8 (Amazon)

Upper radiator hose - $30 (AutoZone)
Water pump - $55 (AutoZone)
Thermostat - $55 (AutoZone)

Transmission intercooler thermostat - $16 (Amazon)

I was able to remove the radiator without being about to tell the water pump had an issue. Installed the new radiator, gave my fan a wiggle and then knew I had replaced two hoses, an expansion tank, and a radiator for nothing. Cost: confidence as myself as a mechanic and an engineer and $295 (didn't replace the temp sensor or thermostat, and I was lucky enough to reuse the transmission intercooler thermostat!!!!!!11!1!!11!!)

I paid $90 for a pack of coils 40,000 miles ago. The entire CCV is $55, you guessed it, Amazon.

One pair of HID headlights - $28

For two years of ownership starting at 153,000 miles and currently at 197,000, 8 months of driving 110 miles a day, five days a week, and now I drive 800 miles a week.

The hardest on this list are the fuel filter (unless you have access to a lift, I hate putting my car on stands) and the CCV, to replace the CCV you have to remove the intake manifold.

The DISA takes 10 minutes if you take the time to drink a beer MAKE SURE YOU BUY A KIT THAT INCLUDES A NEW GASKET

If you have problems head to here or the forums, I feel like I've written a book, but I spent forever tracking a couple issues only to find out it was the plugs. Check the plugs first.

Essential tools:

OBD2 WIFI adapter: $20

Regular socket set: $73

(5mm to 16mm or so, and includes bits you'll really want a wide flathead, Torx 25 or 30 for the cabin air filter mounting screws, and Philips, double check what this one includes)

Torque wrench: $35

6”-8" Socket extension: $10

Fan removal tool set - $20

Including all tools that's $850 Hope this helps, the car is really easy to work on, I enjoy driving it. One last piece of advice never short trip your car, especially in cold weather, you could fill the CCV with mayo and it could lead to hydrolocking/self destruction of the engine. If you live South of Pennsylvania you shouldn't have to worry too much, some people put an ounce or so of Seafoam into the CCV a month. You don't need to follow these links to the tee but they should help.

u/vhalember · 12 pointsr/cars

Oh, I completely understand passing on that car. Sounds like nothing was maintained.

Still, get one, they are very very useful, and cheap. Only $13 for an Android BT reader on Amazon - $18 if you need iOS. If you have Android, download Torque ($5 for paid version, but even free is very good.)

That under $25 set will have more features than the $200-$400+ readers still sold in autostores... and are more up to date, and can easily interface with the web for more code information.

I'll go first, personally any type of wireless OBDII blutooth device that links with a smart phone. Troubleshoot check engine and get live stats of how your car is running. Not to mention it's usually cheaper than a full blown code reader.

u/Lulxii · 11 pointsr/askcarguys

Hey! I started much where you are and had no real way of learning from someone else on what to buy, what to look for, etc. etc. I've got a few tips for you!


When I first started wrenching, I thought I needed air tools. Every mechanic's shop has airtools. Cars are big and mechanical, and it made sense that I'd need something beefy to pull them apart. TOTALLY FALSE. I'll let you know that 90% of my tools are handtools from harbor freight and I probably spent no more than $200 on the collection. Here's a rundown of my most used/invaluable tools:

  • 3/8" drive socket wrench from harbor freight. Composite handle, great mechanism, very comfortable, very light. I have a nice set of kobalt socket wrenches. They don't shine a light on this bad boy in my experience. I have and use 2 pretty regularly. You might be able to get away with just an adjustable wrench.
  • Impact sockets. Little bit beefier than regular sockets, but I very rarely come across an instance when these are not the answer.
  • Color coded deep sockets. When the impacts aren't the answer, these are. I've only got a set of metric, and haven't needed to buy the SAE set yet. I won't buy them until I need them. The color coding seems trivial, but is HUGE when you're sick and tired of being under the car, just want to finish since the sun went down and your tired. Going for the blue socket is much easier than sliding around in relative dark trying every socket to see if it's right. That fucking sucks.
  • Universal joints. Not 100% necessary, so don't buy them until you need them, but holy hell do they make life easier.
  • Extensions. Access is everything when it comes to wrenching. These ones wobble, you might not like that. Try them in the store. Poking 18" of extension up into a crevice is all fun and games until your socket starts flopping around and you can't control it. Double entendre. The alternative are non-wobbling extensions. I have the non-wobbly ones. They've worked totally fine and I don't find that I need the wobble ones.
  • Adapters to make all your junk work together.
  • Breaker bar. When your arms fail you, this won't. Don't go for the cheapest. I did and snapped off the end. Totally fucked myself in my work parking lot.
  • Torque wrench. Almost the most expensive tool in my arsenal. Torque specs are very important. This wrench is cheap as fuck, and people say it's a comparable buy to the snap on wrench. I love mine to death.
  • Adjustable wrench Like having an entire socket wrench set in one single tool. More elbow grease, but very convenient.
  • Body panel pry bars. You will need these for general "gentle" prying on body panel snaps. Where a screwdriver would mess up the paint, these are surprisingly effective.
  • My crown jewel: The impact driver. This is my singularly most used tool. Get this with a set of bits, and you'll be unstoppable. Of course it's not necessary, but it makes 2 minutes of wrenching a 2 second affair. Add it up and it saves a lot of time. These and These are what make my impact driver the best tool in my arsenal.
  • JACK STANDS. Cars are heavy, make sure it's safely supported and you'll be confident every time you go under your car.
  • Jack to actually get your car up.
  • Plywood squares to put under your jack stands, and jack. Jackstands have small feet that sink in grass and asphalt. Plywood stops them from sinking
  • PB Blaster, or penetrating oil. This stuff will pay for itself the first time you use it. Loosens the bullshittiest of bullshit.
  • OBD2 reader This bad boy combined with a $10 app on your phone (DashCommand) will let you communicate with your car's computer. I can read codes, clear codes, see voltage, and boost and vacuum pressures. I can see RPMs, engine timing, rich/lean conditions and any other shit that I'll never need to see. Troubleshooting is 100 times easier with this. Most auto stores will read codes for free, but they won't clear them.

    And that's basically it. Lift your car on level ground. Use jackstands. "Getting to" the actual issue is always like 80% of the work. The work itself is pretty easy generally. Youtube and reddit ( r/mechanicadvice, r/cars, and r/justrolledintotheshop ) are invaluable resources. These people know their shit and they know yours too. PB Blaster is magic oil. If something goes wrong, get it on video for the experts to see and hear instead of describing a skrrt skrrt sound when you're turning left then right, you know? Get cheap tools to start with. When they break, you know that you use them enough to justify better ones. If I've told you not to skimp somewhere, it's because I've skimped there before and I don't want you sitting there defeated. Buy tools as you need them. Start basic, then expand. It's not called a collection because you bought them all at the same time from the same place.


    I got my start by changing my oil. Then my brakes. Then replacing this, then that, and now I'd feel comfortable working on a brand new vehicle. I'm no expert either. Just casual stuff. Building confidence is a big part of it. I wish you luck my man. If you ever need anything, let me know and if I don't have the answer, I'll find it for you.


    To clarify. The tools I listed above are 99% of what I use.
u/5hiftyy · 10 pointsr/mazdaspeed3

The CX-7 turbo has a smaller compressor wheel as well as a smaller compressor wheel housing. This gives you a better low-end torque curve as well as faster spool-up and throttle response. This sort of turbo brings the torque needed for a small SUV with a turbo. The Speed3/6 K04 has a slightly larger compressor wheel and housing, which leads to higher top-end boost translating to more top-end power while sacrificing low end torque and response.

Typically, all the aftermarket turbos are listed as fitting the Speed3/6, CX-7 becuase they are all bolt-in replacements. The problem is if you get a CX-7 turbo, it'll still fit, but your power band WILL change, just like you're describing.

For a short-term problem solver, I might suggest getting a Bluetooth OBD-II scanner and looking at your boost levels. No, it's not the best solution for logging, but it'll do what you need it to. I know my speed3 hits max boost between 3500-3750 RPM; being ~15psi in gears 3 & 4. Why don't you try a 3rd gear pull and see where the motor hits max boost, what that max boost number is, and what RPM it's hit at? This is honestly the only thing I can think of with respect to diagnosing on the cheap, without an AP or pulling the turbo. You may also want to ask the mechanic again for the OEM serial number of the replacement they put in, and compare it to the CX7 vs. Speed3/6 turbos.

The stock MS3/MS6 K04 is typically serialized as K0422-881/882.
The stock CX-7 K04 is serialized as K0422-582.

u/MacEnvy · 10 pointsr/IAmA

>It is normally an $80 minimum charge at a shop to get your codes pulled, and it only takes a second.

Or you can buy a reader for $20.

u/neoMoses · 10 pointsr/Portland

This is the one I have, a couple more bucks but works great. The app for your phone (Android for me, it's called Torque) is $5.

u/ABSOLUTELY__BASED · 10 pointsr/cars

An actual mechanic would probably have some super fancy diagnostic tool, but you can buy a personal OBDII that bluetooths to your phone really well for like $20 on Amazon

u/Barril · 10 pointsr/gadgets

If your car is 1996 or later, you should have an ODB2 port (with some exceptions, google your specific car). The port is usually somewhere under the the dash on the driver side, but a quick google search will tell your where yours is for your car. It looks something like this.

I have used this bluetooth version to hook up to my car, and paired it with my android phone. Take a look at the responses to this comment for the various apps that know how to use the data. I liked Torque, personally.

u/NoOneLikesFruitcake · 9 pointsr/LifeProTips

They go even cheaper so long as you don't mind futzing with the port and cable. Bluetooth would be amazingly more convenient though.

u/Dapado · 9 pointsr/AskReddit

I have a scanner so that when my check engine light turns on, I can see exactly why. The one I have is bluetooth and connects to an app on my phone.


u/diablo_man · 9 pointsr/BlackPeopleTwitter

If you got a "Check engine" light on, and you want to know what it means but dont want to drop it off at a pricey mechanic just for a diagnosis and potentially expensive repair, head over to amazon and pick up one of these blue tooth OBD2 scanners. That ones for android(I have it, works great), this one works for iphone and android.

That plus a typically free app like "Torque" let you find out the error codes your car is throwing out(and all other kind of basic diagnostic stuff), so you can google it and see if its something you need to fix right away, could easily fix yourself(with youtube), or if its just a minor problem you dont need to worry about yet.

And if you do take it to the shop, you can probably save them some time(and thus money for yourself), and being more informed, keep yourself from being taken for a ride.

If your car is 1996 or newer it should have a port for these(typically under the steering wheel above the pedals), save yourself some anxiety about that new warning light that just showed up.

u/odd84 · 9 pointsr/leaf

First, some background: The percentage display on the dashboard is only loosely related to the actual state of charge of the battery, because the battery management system reserves a buffer at both the bottom and top end of the charge range to protect the longevity of the battery. When you charge up to 100%, there's 38-39 kWh in the battery rather than 40 kWh. The highest I've gotten the true SoC (state of charge) of the battery to when it showed 100% on the dashboard is 98.2%, but 95-97% has been more common. Similarly, when it says 4% on the dashboard, there's a good bit more than 4% of actual charge still in the battery. It's like how you can drive many miles after the meter reads "E" (empty) in a gas car. After 0% it'll show "--%" if it's like previous year Leafs while driving quite a few more miles, then you'll get a turtle icon and reduced power for a final mile or two to safely pull over. At that point, the car will stop moving, but there's actually some kWh of power still in the pack, because running a lithium ion battery down to real 0% permanently damages it and the car won't let you do that.

THAT SAID, I am slightly concerned about what you've said. I did a 60 mile highway drive yesterday with the A/C on full blast in 90 degree weather and >70 MPH most of the way, and still averaged 4 miles per kWh. I don't think I've ever gotten only 3.2 miles per kWh in the new Leaf. I've had many trips with more than 5 miles per kWh on 35-45 MPH roads. I am easily getting the 150 miles per charge, so if you're only getting 80-120, that sounds wrong.

This sounds silly, but what are your tire pressures at? The difference between underinflated and overinflated tires can easily be 10% or more on your miles/kWh efficiency. I have mine at 42 PSI right now. When a new car shows up at a dealership, one of the things they do to prep it for sale is to let air out of the tires, because they're shipped overinflated. If they let out too much, you'll want to pump them back up above 40 PSI (well above the 36 PSI the sticker says to inflate them to, I know) and go on another long drive to see if that improves your efficiency.

If that doesn't work, the next thing I'd do is get on Amazon and order this OBDII scanner and download the Leaf Spy Pro app on your phone. That will let you see the real State of Charge in kWh for your car whenever you want, which will help you figure out if there's a real issue here.

u/JeffersonianSwag · 9 pointsr/personalfinance

It looks like you can also buy them at Walmart but if you have an iPhone, it looks like they’re slightly more expensive, but worth it the cool thing about these is that you can also monitor RPMS and engine heat and, if you get a check engine light, it’ll give you a “code” and you can just google it and it’ll tell you what exactly is causing your car to throw a check engine light

u/Kooriki · 9 pointsr/vancouver

I bought a car from the auto auction in the late 90's (CAAG in Surrey). Back then it was a risk v reward thing as you're never sure exactly what you're getting. You can browse the cars beforehand, start them up but they are packed in so tight you can't really drive them.

Plenty of deals to be had but its largely influenced by how popular it is that day. Best times is low season (Oct-Feb), and if it's raining. Mid week was better deals than weekends.

To judge prices, ignore blue book; Check Craigslist. Craiglist is the market.

Buy an ODB2 sensor to check diagnostics. (Depending on how old the car is, it may not work). Before every auction the auctioneer will call out any declarations and it will be on a big board (out of province, salvage, not legal etc)

The atmosphere is hectic and crazy and confusing and exciting, but once you've got a couple of times and see how it goes its not bad at all. If you want to bid on a car, have a price in mind and put your hand up if the price is right. An auction worker will come over to you and call the bids out for you so you're not confused by all the hand signals and yelling. If there is a reserve price on the car and you don't meet it, you can negotiate on the spot with the seller (standing near the auctioneer) if they are willing to take less than the reserve.

Try not to feel intimidated or bullied. Get a price in your mind and work with that.

Last note: You're going to have to settle price and insurance quickly, but they do have a broker on site to do transfers/reg/taxes

Hopefully this helps. My experience is close to 20 years old, but I spent a TON of time at the auction place and got a real good feel for how it worked at that time.

u/garynuman9 · 9 pointsr/funny

Bluetooth OBDII readers are ~$10 on Amazon!

Combine one with an app like torque- lite version that reads codes and does the basics is free, pro is like $5 and has bells and whistles.

This way, as opposed to simply reading the codes, you can get real-time data directly from your car's ecu.

Shits amazing for ~$20. What you save in repairs by catching issues before they turn into expensive problems is amazing.

Hey all, I got a bunch of info from here and the forums, so I thought I would give back and drop a few links.

First is the roof rack. I think the rola roof rack is the best looking and ends up being one of the cheapest.

Next up is the cargo box. I thought getting one this long would look stupid, but it's way better than I imagined. The rocketbox 11 is one of Thule's cheapest and big enough to fit my huge board in. No noticable drop in mpg, either - hovering barely above 33.

The backup camera is a fantastic upgrade. I followed this post and dug into the forums posted there. I would double check the apim codes because it's a tad dangerous and I didn't use the same exact codes as u/brbauer2 (I have the 2016 w/ sync 3). Shoutout, by the way, the album was super helpful. Also, the pins we inserted to the wiring harness didn't connect with the head unit, so I shredded a small amount of foil to bridge those connections.

Canying Car Trunk Handle Rear...

BAFX Products Bluetooth...

And finally, I like having my windows down in the rain, so I got them smoker vents.

Maybe someday I'll get that accessport/intercooler and a rear motor mount, but I'm loving it as it is!

You all bought awesome cars, thanks for the help, catch you later.

I just use my retired Galaxy Note 2 with a lightweight lollipop ROM (liquid smooth) and this

~ mount Only $10 and free one day shipping if you are a prime member. It won’t open any wider than a note 2 but it holds securely to both the phone and the dashboard even in this 0 degree weather outside right now. Wish I could leave my phone out in the cold too. I hate North Idaho.

~ Dashcam - I use Dailyroads Voyager It uses cyclic recording so it can keep overwriting and not using up too much space. It can run in the background while I use waze, music, OK Google, etc. You can also set it to save the video when it senses x amount of G forces. Or you can tap the screen at any time to save the video… It has tons of features and the shocking part is it’s free! Since work provides me with unlimited data tethering on my phone I also utilize it’s cloud backup feature.

~ OBD II - For car diagnostics reading I use BAFX OBD2 I was literally shocked at how easy this was to plug in and pair to my phone! For close to $25 I had tons of information about how my car is “feeling” right in front of me. I’ve only tested a few but I stuck with Dash Some of the things it tells me are engine temperature, engine load, speed, MPG, coolant temperature, RPM, air/fuel ratio… anyway, my favorite part of the app is how it keeps track of my trips.. locations, statistics, where I last parked. Love it.

Things I’m still working on are getting an inverter in my trunk to power a small/cheap router and raspberry pi plus small ssd so that in the case of theft my dashcam app could save to the ssd in my trunk to catch the filthy thief. Looks like there is enough room behind the plastic cover where they keep the tire changing tools to keep this equipment hidden from sight. If anyone has better ideas please let me know. Maybe someday I will impress a nice guy ………

u/brmo · 7 pointsr/Android

I am doing the same thing in my 2010 Ford Escape. I ordered a double din dash kit off amazon, made the hole a tad bit bigger and i already fiberglassed the tray that i will use to slide it in and out of.

My plan is just like yours, torque, nav, music, etc. I already have a Turtle Beach USB Audio sound card, for usb OTG, where a powered USB hub will be used for the sound card and the 64gb usb stick. (Works great btw.).

The only issue I have right now is power, while its not important, especially when using a powered USB hub, I still feel comfortable with it charging while its in my car. So the project is on standby until the pogo pinout gets figured out (should know as soon as the official dock launches), and then go from there.

So far here is my parts list:

That really depends on the code and the vehicle. If you are outside of california just stop at any chain parts store when the light is on and get the code read (they'll do so for free). Get the actual code from them, not their diagnosis. You can also get a cheap bluetooth OBDII reader and the free torque app if you have an android phone or tablet. Then you can check your own codes.

u/MotoSparky · 7 pointsr/Tools

On Amazon they have bluetooth scanners for Android. Runs about 25 bucks. Best thing ever, plus you can possibly pill real time info depending on your car, an added plus to trouble shooting. This is the one I bought. There are some cheaper now though!

u/RabidBlackSquirrel · 7 pointsr/BuyItForLife

Grab an OBDII reader, for ~$20. I've had this one for several years. Put Torque Pro on your device and go forth and diagnose. You can get a dedicated handheld tool, but I prefer the features of using Torque. Some cool addins available for it too.

u/PNWTim · 6 pointsr/LifeProTips

There's a smaller sized blue OBD2 plug in on Amazon it goes along the lines of "panlong" or something, it's only like $10-15, works fine in my Lexus and Mercedes, it's able to clear errors and stuff, real-time info works well. And it's really low profile unlike those other adapters so if it sticks straight into the foot well it won't bother you

Edit: it's $11

Works fantastic with torque pro

u/FrunkisOA · 6 pointsr/opieandanthony

If you're getting engine lights. Buy this for $12 (or go to AutoZone or something but that's a pain in the ass) get "Torque Pro" in the play store for $5, get the engine codes. Google those codes, then go fuck your mother.

u/SyntheticManMilk · 6 pointsr/IsItBullshit

I disagree. I actually am happy with the current systems in modern (minus the dash board touchscreens. Fucking hate those things, just give me knobs and buttons!). In my opinion they are easier to work on. Hear me out.

I was broke through my 20’s, so whenever I had car trouble it was either “fix it myself, or don’t have a car”. I’m not a mechanic, but I’ve learned a thing or two about car repairs. Even though I can afford it now, I still fix my own car because I’m now aware of how much mechanics gouge people.

I can’t speak for all the cars, but I just like the way components were placed in my car. I drive a current model Grand Cherokee and everything is just so clean, spacious, and well organized under the hood. The difference between my modern car compared to my older cars is kind of like this. I can access major components much easier now that it’s not a cramped mess down there anymore.

With computers running everything they possibly can though, there is a downside. The thing people like to complain about is how a computer can fail and kill the car. A dealership will try to charge you well over $1000 dollars to “fix” a computer, but you can just order a new computer online for like $200 and replace it yourself (it’s easier to replace than any mechanical component). I actually like the computer systems because they do a fantastic job of monitoring all kinds of things making preventive maintenance a breeze. Playing with this thing has been very fun. Buy one and save yourself the $100 your dealer mechanic would’ve charged you for just to tell you what’s wrong.

Also in general, today’s cars are better than ever in general. Most of them are built to last longer now. Also, the basic major components are still the same (axles, exhaust, brakes, differential, underbody stuff) and are no more or less harder to work on now than in the past.

u/monsieur_le_baton · 5 pointsr/StupidCarQuestions

personally i wouldnt speculate on what your check engine light might be caused by, any of the answers listed by other people could be the cause. Someone else has mentioned going to an auto parts store and getting the codes read, thats the best idea, or buy your own reader, they're $15 on Amazon it spits out a code you look it up by googling 'chevy malibu code xxxx' and it will tell you the issue, and the chevy forums can tell you whether you need to worry about it or not.

I bought this bluetooth reader off Amazon and the Android application "torque".

Not only does it let me read and clear codes, but it gives me all sorts of real-time information which is cool but useless to me since I'm not tuning my car (vacuum/boost, rpm, timing advance, fuel flow, throttle position, intake temperature, etc.). Not bad for like $30 for the reader and the app.

Not a tip, but a warning: Get used to people cutting you off or trying to go around you at all costs. Had some douche pull the "go around" this morning, but I was trying to avoid an accident as some dickhead cut me off. Then I ended up flying by him at 85 mph just moments later.

u/Do_not_reply_to_me · 5 pointsr/answers

Quick answer: Holding the button for 5 seconds forces the engine to turn off

Long, rambling and occasionally off topic answer: I have a manual gearbox ford with push button ignition.

When you're driving, the push button doesn't turn off the engine. It goes into a special mode above some minimum speed like 5mph. If you decide you do want to turn off the ignition while driving you can override the lock out by holding down the button for 5 seconds.

I don't recommend that you try it, because I don't know under what conditions the steering lock will kick in. I expect it won't engage until the car is stationary but I can't be sure without testing that so my advice is leave this stuff to idiots like me to find out. I've done that once before in a traditional ignition car (pulled the key out while driving and the steering lock engaged and I drove up the curb onto the verge before I could stop the car).

So anyway, I tried the power button thing the other day because I was curious, I pushed the clutch down so that I was freewheeling and pressed the button while rolling forwards at about 10mph and nothing happened. Then I held the button down for a few seconds and the engine cut out. I quickly pressed it again and the engine started up (I wasn't ready to test the steering lock thing on that occasion, maybe next time).

Specifically about the computer crashing: OK, so what I've described above relates to normal operating conditions. The car performing as intended. What about a software crash? I can contribute something on this as well although I'm not a vehicle designer.

I have a cheap Bluetooth diagnostic module, [like this] ( Not that exact one but something similar. Mine is modified with a switch to enable dedicated Ford diagnostics using some software called Forscan.

So the switch allows me to flip between standard OBDII wiring and custom Ford wiring. It's important that I flip the switch to the correct position when Forscan is sending out Ford commands or OBDII commands.

I flipped the switch during a session, sending signals down all the wrong wires. I was driving and attempting to diagnose an exhaust issue. Whatever I did, I did it at exactly the wrong moment because the car completely shit the bed.

The instrument panel crashed, all dials went to zero. All readings (mpg for example) went to dashed lines (--- mpg). "Shit. I hope this isn't permanent" I thought.

The engine went into limp mode (reduced power). I was pretty concerned so I pulled over. Basic controls were still working gas (with limited power), brakes, power steering. But nothing complicated was working. Cruise control gone. Even the power windows wouldn't auto close, manual close only.

Anyway, I'm an IT guy so I figured the old favourite "turn it off, and then back on again" was called for.

I pressed the stop/start button. Nothing. "SHIT" I couldn't turn the fucking car off, even stationary. "SHIT, FUCK". Then I remembered about holding down the button so I tried that and it worked!

It seems like Ford planned for the worst case scenario and wired a pretty low level override into the button. Even when the whole computer system had given up and shut down, the override still worked.

u/thehauntedmattress · 5 pointsr/iphone

It is 100% possible to use a bluetooth OBD adapter with iOS. I currently use the LELink OBDII with my iPhone 6s Plus. I bought this one for the exact same reason you did: I wanted to be able to have internet and be able to have my car diagnostics. I use it with the OBD Fusion app and works like a charm. The thing works so well that I can have my Apple Watch (the app offers an Apple Watch app so therefore it is meant to be connected to a watch and phone at the same time) and my car's audio system connected all at once. That's three different Bluetooth devices connected at the same time.

Edit: This solution is $55 less expensive than the Automatic device.

u/stealstea · 5 pointsr/VictoriaBC

I bought a used Leaf 2 years ago from a private seller. Interestingly enough used prices for Leafs are up since then. After driving the car for 2 years the car is worth the same or more than when I bought it.

Advice for buying now:

  1. Buy an ODB adapter and the LeafSpy app or similar
  2. Test the vehicle before buying it and check the Battery State of Health (SoH) and Hx values in LeafSpy. Higher is better. Motorize will give you LeafSpy output for their Leafs but Campus Nissan will not. Their official Nissan battery report is useless.
  3. If you can find a Leaf that came from Washington / Seattle that's generally better than California because the heat is what causes battery degradation so those from the pacific northwest are usually in better shape.
  4. In Victoria Motorize are the better dealer but prices tend to be a bit higher than campus nissan but they are more honest. Cross shop both of them. If you have the time you can likely find even slightly better deals in Vancouver.

    Enjoy! I'm liking mine after 2 years. Battery not as good as a Tesla for sure for less than a quarter of the price I'm ok with that.

Don't get something old from the 80's or 70's. it'll just make getting parts harder.

If you want a reliable beater that will be easy to repair get a 90's Honda. They are simple to work on, parts are plentiful, and as a daily driver they get amazing mileage. If you yet an obd2 model (96 and newer) get one of these so you can scan the codes.

  • Learn how to change a tire. Do it in your driveway or in a parking lot on your own. It is a lot better to know how to do it right when you need to. And it is much easier to learn how on a warm sunny day than on the side of the road in the rain, or the middle of the night.

  • Keep a tire pressure gauge on you. If your tires appear low, check the pressure. Tip: Sheetz gas stations (at least the ones in Virginia) have free air (most gas stations do). Their systems have a digital pressure setting and an auto-cutoff. Just set the pressure, and it will stop filling when it gets there. Otherwise use your pressure gauge to dial it in. Most cars will feature the tire pressure for front and rear tires on a sticker in the front door frame.

  • Water will work as coolant in the summer. If it is colder outside, you will want to buy antifreeze. Most gas stations will sell it.

  • If a warning light on your dash comes on (check engine, oil light, alternator light, etc) you will need to get it checked/fixed soon. Check engine lights can sometimes be nothing (sometimes it is just a loose gas cap), but it is always good to get it checked. More on that in a minute. If a warning light on your dash starts flashing, that is a serious problem. Pull over, turn the car off, and call a service station

  • You can save yourself some money by getting an OBD2 Reader. These read your check engine codes and tell you why your check engine light is on. Some shops will do this for you for free, some will charge $20. Most corporate owned auto stores will let you borrow theirs in exchange for your drivers license. Personally, I say just drop the $20 and get one, it saves time later on. They sell ones that are much more expensive, up to thousands of dollars. You don't need these; these give "live" data of the car's sensors and other things that won't help anyone other than a mechanic. A small $20 one will read the code and probably clear it if you want.

    Simple run down on how to use them (should be in the instruction book). 1. Plug it into the car, with the car turned off. (The plug will almost always be under the dash) 2. Turn the key to the ON position. (Do not start the car, just one click before it. Like if you wanted to turn the radio on but not start the engine) 3. The code reader will usually say READING for a few seconds and give you one or more codes. They will look something like P0430. Cheap readers usually have books with them that will tell you what they mean. More expensive ones ($100-$200) will define the code. If you don't have the book, just google the code.

    Depending on the code, you may or may not understand what it means. This is okay. If you google the definition of the code, you will almost always find someone describing the general idea of what is going on. Again, you might not be able to use this info to repair the car yourself, but it can give you an idea of how serious a problem is, and may prevent you from being ripped off by mechanics.

  • Anticipate maintenance and repairs. Tires are expensive. Thankfully, they don't need to be replaced all that often, but changing 4 tires at once can easily be $300 bucks for cheap new tires. Avoid used tires. Keep $100 saved up to get the oil changed. Newer oils need to be changed less often, but the shop should advise you when to come back. (I'm assuming you aren't planning on changing your own oil any time soon) Nothing is worse than knowing your oil is dirty and overdue for a change but not having the money to make it happen, and old dirty oil will shorten the life of your engine.

  • Every 6-8 months, when you get gas, go into the gas station and buy fuel system cleaner. It will look similar to this. Simply pour the entire bottle into your gas tank and then fill up your tank to the top. Also, and this is very important! DO NOT PUT THIS IN A DIESEL VEHICLE

  • Finally, find a good mechanic/service station. Ask locals around your town. Check reviews. The difference between a good one and a bad one can be hundreds, if not thousands. Before I learned about cars, I went to several mechanics for my first car.

    One never updated me on their progress, charged super high prices, and recommended unnecessary repairs. Then I went to one that would come out and talk to me 2 or 3 times throughout the repair (giving me updates, letting me know of other problems he noticed, etc), he would never perform an additional repair without taking me into the shop and showing me exactly what he was talking about. At one point, he ordered brake parts from down the street because I thought I needed new parts. Turned out it was a whole different issue with different parts. He happily sent them back, free of charge to me, and walked me through what he was going to do. I still take my cars to him when they have "gremlins" that I can't figure out. Usually they charge a pretty big service fee per hour, but from the very first time he charges me 1 hour less than whatever it takes him. His reason is always "I wanted to figure it out as bad as you did. Forget the money, this thing became my puzzle."

    But I've been rambling on that. Point is, find a good mechanic and stick with them. It will make a huge difference.
u/WRSaunders · 3 pointsr/explainlikeimfive

It's easy:

  1. Find out why the light is on. This could be a loose gas cap or a real problem. There is a $14 code reader gizmo for this.

  2. Fix the problem. This of course depends on what th problem is.

  3. Reset the MIL (that's the real name of the "check engine" light). Your reader gizmo can also do this.
u/vinnyvecchio · 3 pointsr/cars

That's what I assumed unfortunately.

I got a $20 scanner on Amazon, and it can check inspection monitors. It's a simple tool, but it will go through the list of monitors (evap, cat, etc.) and tell me if it is ready or not.

I guess I will just have to hope for the best if I don't see any CELs. Thanks for the answer!

u/eck- · 3 pointsr/Cartalk

It's worth getting your own. I have an Autel similar to this one. I've only used it once and it retrieved the code no problem.

u/NeptuNeo · 3 pointsr/LosAngeles

I recommend buying from Amazon a diagnostic code reader so you can read the check engine codes yourself and verify what the garage is telling you. I bought one a few years ago for only $15 and it works great, there are newer/ better ones now but here is the one I use:

u/Kirsanth · 3 pointsr/Calgary

It wont help you now but you can get OBDII bluetooth receivers off ebay/amazon for about $20. You can hook them up to your phone and read/clear codes with the Torque app (free version).

u/SherrifOfNothingtown · 3 pointsr/Adulting

> how and where do you get the car registered?

If you're in the US, you phone the local DMV and ask them how to register the car. You probably go to an office, write a cheque, fill out forms, prove that you didn't steal it, and then get registration.

If not, you text a car-savvy relative and ask them who you contact.

> How do you know when something is broken, and how do you fix/handle that?

You suspect that something is broken if a dashboard light comes on or if the car makes a motion or sound that it didn't used to. Then you Google it, watch some YouTube, read the car's manual, and maybe take it to a mechanic. For most newish cars you can also plug one of these things into a port under the dashboard, pair it with an app on your phone, and listen to the computer telling you what it thinks is wrong with itself.

> How do you choose a mechanic that isn't awful?

I dunno... Ask your friends, and read online reviews? How do you choose, like, a doctor or a lawyer?

> What are the basic parts under the hood, and what do they do?

Depends on the car. Depends on if it's gas or diesel. Probably best to Google your exact model of car once you've picked one.

> What sort of insurance coverage should I get?

If you're in the US, your state probably has a legally mandated minimum amount of insurance. If not, uh, ask someone car-savvy whom you trust.

> Etc.

  • Read your car's manual (or download a pdf if it didn't come with one) to find out about its routine maintenance schedule. Fluids and stuff need to be changed every so-many miles or years, and the specs depend on the model of car.

  • Check your lights, and use a mirror or friend to check that your brake lights work.

  • Check the oil and tyre pressure every week if you drive a lot, every month if you don't.

  • If you haven't committed to a particular model of car, look at this

  • Before you actually purchase a certain car from a certain year, Google around to see if it has a common failure mode. Like Honda Fits are generally great but the 2007 ones have a problem with one of the seals around the door leaking so rain gets in your car.

  • Take someone car-competent with you when you test drive.
u/FF0000it · 3 pointsr/BMW

Go buy a $15 blutooth OBDII reader as well as Dash Command if you have an iPhone, or there's also an equivalent Android app, $9. It'll spit out the actual code thrown, and you can look it up online.

u/jtm141990 · 3 pointsr/GolfGTI

This is a cheap Amazon version of what I use to integrate with my Android phone. If you have a phone that can use the Torque app, download it (the free one works just fine) and connect your phone and the OBDII reader via bluetooth. It will display the code and give you the option to clear it. I do this every once in a while because the O2 sensor in my downpipe trips out every once in a while and throws P0420 at me. If after you clear the code using Torque it comes back, you probably have a problem you need to fix.

u/DrubieDaGuru · 3 pointsr/SubaruForester

I'm glad someone else likes this stuff too!

Yep, I use a cheap bluetooth OBDII adapter like this one and the $5 torque app on my android phone. The free version of torque works well but is limited. Unfortunately, for i-devices you'll need to buy a more expensive one (like obd-link) or get one that communicates to your phone via wifi.

I upload the log to Dropbox and do some quick Python scripts to analyze and plot some things.

I apologize in advance for this long post. None of these are "must gets", but they are what I got for my 2016 Premium forester. I'm posting this for my own future reference as well as to help some people who are wondering what accessories might be good for their new forester. I highly recommend ordering from Jackie from Annapolis Subaru @ 443-837-1422 as she can get you some good prices on the subaru accessories as well as WeatherTech products! I saved on WeatherTech shipping costs (~$20) by ordering through Jackie and the warranty is the same as if I had bought them through their website.

Please note that some of these accessory links are for my specific car year, model and configuration. I have a 2016 Premium forester without eyesight (affects the Covercraft/heatshield sunshade - they also have eyesight compatible sunshades!).

u/KingClam2 · 3 pointsr/Cartalk

OBD2 isn't something for people with expensive cars, just... vehicles in general. It's the way your car tells you what is wrong with it.

big old list of Honda trouble codes

Most stuff that goes wrong in a car, there is a code or set of codes which will tell you what to check/fix/clean/replace

Can read or clear. Can check pending, current, or historic.

Can run KOEO and KOER self tests

>to put on my vehicle.

Not a permanent addition to your vehicle. I mean, you can... but no need to think of it that way.

here ya go, there are some partially defective obd2 adapters out there, but this one is legit Read their item description.

u/darwinopterus · 3 pointsr/femalefashionadvice

I just had to shell out a ton of money for a new window regulator because I shut the door and the window FELL DOWN INTO IT, so I totally feel you on the stress thing. I'm constantly worried something else is going to happen. Last year and the year before I was having problems with my throttle body, and it was entering throttle failure mode while I was driving, so basically the car stopped working while I was on the road. Utterly terrifying. Only happened once on the highway, fortunately. It's fixed now, but I'm still paranoid it's going to happen again.

This won't help now, but you can buy an OBD2 wireless scanner and plug it into your car to get error codes, and there are some pretty good apps out there that will tell you what the codes mean. I have one and it makes me feel less anxious because when I take it in, I can tell them exactly what code I got so they'll be able to pinpoint the issue more quickly.

u/rgoertzen · 3 pointsr/VEDC

I purchased a [BAFX one from Amazon] ( that has worked reliably for me. $22 currently, though this one is Android only. Don't know if that's a problem for you.

u/Complexifier · 3 pointsr/AdviceAnimals

No, the OBD2 scan tool has bluetooth. Your car has a place to plug it in, then you can connect to it using an android phone/tablet with torque.

u/graymulligan · 3 pointsr/motorcycles

So I thought that too, and someone else saved my day so i'll pass it on.

Motoscan. (I don't speak iPhone, but there's a version available)

You'll need a Bluetooth OBD reader, and the conversion cable for BMW's round port.

Plug it in, install the app (you'll need the middle tier to do resets, I think it's 23 bucks), connect, and more service lights. Plus, i's the same OBD reader that will likely fit your car's OBD port, so its handy if you get a trouble code on the car too.

u/LJ-Rubicon · 3 pointsr/MechanicAdvice

Yea, that's 2nd grader level science experiment style, if I'm being honest. There's so many variables and loss of solid testing in the way you did it, that it really shows nothing.

You need to get this (or one like it)

Then get the Torque app

You'll then be able to read actual, real time fuel consumption

u/Flipper303 · 3 pointsr/BmwTech

I'm going to be straight with you. Save 50-100$ and buy yourself a bluetooth scanner. I bought this an installed the app Torque Lite (free) it has saved me so much cash it's not funny. BAFX Products - Wireless Bluetooth OBD2 Scanner

Plug it in, itll pull the codes from your car, you can look them up on forums and boom. Diagnosis for free. I hope this helps!

I've been taken too the cleaners too many times. Those people run a business and need to make money. Some do it honestly, some dont.


u/Snownel · 3 pointsr/CrownVictoria

It's free, see here, you can register as many 3-month trial licenses as you want. It requires an OBD2 reader that plugs in under the dash, I use this. It also requires a laptop with Bluetooth. You can do a lot of diagnostic stuff with Forscan but you can also connect that OBD2 reader to an Android phone if you have one and run apps like Torque.

u/maverickps · 3 pointsr/Libertarian

Spend a few bucks on a code reader:

and the torque app is free:

it can clear the codes too w/o pulling battery cables.

u/JacePriester · 3 pointsr/MechanicAdvice

Oooh oooh, I know this one!

So Matraxia is pretty much right, whatever is cheap, but I'll give you some more info you should know.

Pretty much all of the OBDII scanners out there, at least for consumer use, are based on the ELM327 IC. The ELM defines a serial, text-based protocol as an input, so you (or an app like Torque) give it a series of commands just like it were a modem, and then it handles communicating with your vehicle via several different protocols, all pretty much transparently. That's why one program like Torque can talk to pretty much every vehicle, via the ELM chip's magic.

The thing about that is, the firmware for the ELM chip got leaked a long time ago and there have been unlicensed Chinese copies made ever since. The real ELM has had upgrades since then, and the Chinese version has sort of kept up, but in the knockoffs some things work right and some things don't. They're frequently slower, buggier, or don't support certain commands, compared to the real ELM chips.

So how do you tell which you're getting? Mostly the price. The knockoffs are cheap, like this one:

No way that's a real one. Not for 4 bucks. That said, I have no idea what the cutoff is where you might consider it legit.

Personally, I have this one:

I have sent it a number of commands over the serial terminal to verify that it's a real ELM327 chip and it has passed all of my tests. That said, it could still just be a good knockoff with a lot of the ELM's newer commands implemented. I really don't know for sure.

Either way, works great.

As for gathering data and exporting to excel.. that has nothing to do with the OBDII adapter you get and everything to do with the software you run on your phone. I have no idea of Torque or others support this but it seems like they should.

u/ruscan · 3 pointsr/Volkswagen

Sorry I forgot to respond. What worked well far me was the following:

  • BAFX Bluetooth OBD Scan Tool - $23.99 (I've seen them price it as low as $19.99 though depending on the day, may be worth watching the amazon page for a couple days)

  • Carista Android app - free download but it costs $20 to unlock the feature that actually lets you apply new settings.

    I can vouch for this combination as I was able to successfully use it to configure options (such as windows and fog lights) in my CC. No problems. The only catch is that they claim the BAFX tool only works with Android. I have an Android phone so it's not an issue for me. If you have an iPhone you may have to look for a different tool. Carista actually sells one on Amazon but it's pricier ($40 last time I checked).

    This won't get you the full array of features of a real VAG-COM but it's also $200 cheaper.
u/the4thmatrix · 3 pointsr/FocusST

You cannot make the screen permanent without an OBD II reader, but you can access the splash screen by going into the testing settings of Sync 3 (hold down track forward & eject), bypass the speaker test screen, then press Testing Settings, then change the theme to Ford-ST. When you power down your car it'll show, but upon startup it'll go back to the default Ford-timeless theme.

As far as I know the only way to make the change permanent is to change the hex value in Forscan. I was able to change it with this OBD II reader from Amazon. With that being said, the version of Sync 3 v2.2 going around the internet is not the official release so the one that is finally released to the public may have the ST logo enabled by default.

This. Pick up any Android phone for uber-cheap (just has to have bluetooth and Android 2.0 or higher), buy Torque for $5, and buy one of these adapters for $24 Prime.

u/neilthecellist · 3 pointsr/leaf

Yes, what this person is saying. Download Leaf Spy Pro (yes, it'll cost you a few bucks off Google Play, oh well), and get an OBD (I got this one - ANY Leaf you come across, plug it in, load up Leaf Spy Pro, and look at the top right number in the main screen. Here is an example -- the 50.8% at the top at 67.4% SOC (state of charge) means the car is probably around 75-77% SOH (state of health) -- you don't want to buy a used Leaf like mine with that much battery degradation unless you just won't drive long-distance (my trips to Portland from Hillsboro are very rare, only about once every two weeks, and it's only 35 miles roundtrip).

BTW for anyone wondering from my screenshot, yes, the battery does get that hot. It's 85 F outside right now outside my house, and I just came back from the grocery store. Yes, Leaf Spy Pro does indeed say my battery is at 127 F. One time I came back from Portland and my battery temped at 205 F according to Leaf Spy Pro. This is what us Leaf customers get for buying an EV with no thermal management system...

u/dlesinski · 3 pointsr/Trucks

I bought one on Amazon for like 25 bucks a while back. The app I used with it, Torque, is only available on android. Really good app though. No problems with the scanner itself. Had a good range too.

u/clockworkdiamond · 3 pointsr/WRX

Scan the ODB2 port and see what the code is. From there, you should at least know what sensor is throwing the check light.
I had similar issues that the dealer would just reset, so I got a Bluetooth scanner that I just leave permanently connected. When it goes off, my phone looks the code up and if it is bullshit, I can just reset it myself. I use Torque as the software. Pretty cool to just watch all of your data with it too.

Clean looking model :) congratulations! Love that you have sunroof / moonroof (different countries - different names - same stuff).

Waiting for the interior pictures.

Here are few link where you can find info and parts in case if you will need; searching by VIN number, only the last 7 characters, CE7.... and for parts number for equipment details, with which the car came from factory

Others; using apps

Torque pro or Torque lite - free version to use together with an OBD-II bluetooth scanner for quick diagnostics, are not expensive and can give you some quick info.

Another good app which I tried, a little bit more expensive, is Carly for BMW they have a free lite version as well Carly for BMW Lite only that you will need to have a smartphone which knows USB-OTG and a cable from them (from carly for bmw) adapter search which can be 30€ carly for bmw website

I tried them both, torque and carly, and I would say that they are good enough, can give you informations, faults (errors code) and you can search by error code number to have an idea what can be the issue; as well can clear faults.

Carly for bmw knows coding as a plus, you can configure your car to do other few things, such as automatically locking the doors when going over a certain speed, follow me home lights on time for a certain time, keeping pressed locking button from the key fob to fold the mirrors (+ windows to go up), keeping pressed unlocking button from the key fob for the mirrors to go down; plus other few stuff (can't remember). For a car from the years 2000s is having few nice features.

Take a look at youtube video 5 Series - E39 - Video Handbook (40mins video) and you can learn about them.

You will have to prepare for the future, in case if they will fail, about kit repairs.

In US you have German auto solutions with DIY instructions, tools, kits; very useful stuff.

Since recently I had issues with this hose 11531705223 Radiator Hose which I had it replaced and just blew (snapped) after 1 year when I was going up the mountain, they are know for failing and can leave you stranded; give it an eye inspection.

What else can I continue recommending you... uhm...

Take care of it and again, congratulations :)

This is the ODB2 BT I got, works great:

Take a look at this for the L2 charging:

It is super easy to convert your existing L1 "charger" (it's not really a charger) to be both L2 and L1 capable, then you just need a 240v outlet (which is ~$100-$200 for an electrician to install, easy to DIY as well)

I have yet to do any public charging, but just signed up for a ChargePoint account, thanks to the account should work at ChargePoint, Blink, and EVgo station which is 90%+ of public stations. Maybe someone else can comment how well it works and if it's still a good idea to sign up for multiple provider accounts.

They've come down quite a bit, because many now just relay the data via bluetooth to read on your smartphone/tablet. I diagnosed an issue with mine with this $10 Model and a free app.

u/poolecl · 3 pointsr/SubaruForester

If you want to use it with an iPhone, you need WiFi or Bluetooth LE. A "regular" Bluetooth one won't work.

I bought one of these for $35 and a generic WiFi one for about $15. There is a little more support for the WiFi one in more apps, but the Bluetooth one will be a little simpler because you don't have to switch wifi networks.

You may want to get an extension cable, they are tiny so easy to leave connected all the time but really hard to take in and out. If you got some sort of pigtail cable it will probably be easier to disconnect.

So those should be able to tell you the specific codes needing attention as well as an option to clear them if you want. Of course, clearing doesn't do you any good if you don't do anything about the issues, it can very well come back. But once you have the specific codes, look them up online and see if you can pinpoint the possible issue and get it fixed. At the very least, you can know how serious it is.

u/gamebrigada · 3 pointsr/cars

No worries.


You need to start with figuring out why they want you to replace your entire exhaust system. Is it throwing a code? Is it rusted to pieces?


Your car is fitted with 2 Cats, 3 O2 sensors, a resonator and a muffler. The absolute most expensive component will be the first cat, as it is part of the Exhaust Manifold. The cheapest one I could find from a half-reputable source is here at 350$. The rest of the system is pretty much bog standard and can be done by ANY exhaust shop without official parts. They probably also want you to replace the O2 sensors. These are generally expensive items but you are pretty lucky. You should have 3 of them. Upstream, Center and downstream.


If you absolutely have to replace the whole system, do some research for reputable exhaust shops. Just google it and look at reviews. Talk to a shop of your choosing and ask them if you can provide the Exhaust manifold and sensors, and if they would be willing to do the rest. Since after the exhaust manifold, its a bone simple exhaust, a shop with a good welder will be able to throw together an exhaust for you from basic components in less than a day and much cheaper than buying all the pieces separately. Some shops will want to charge you more than 200$ for the second cat. Give them the finger and buy the secondary from RockAuto. At that point its just some pipe bending, a resonator and a muffler. I would be surprised if they want more than 300$. if you include both cats. That puts you at 470$ for the 2 cats, 75$ for all sensor and 300-400$ for the rest. That puts you under 1k$ for the whole system.


The more likely scenario, is that they are just pissed off at a code your car is throwing (Your check engine light should be on in this case), I would start with buying a cheap OBD reader, or going to an OReilly's/AutoZone to get your ECU read and write down the code.

Here's one that will work with an Android Phone.

Here's one that will work with an iPhone.

Once you get the exact code the ECU is throwing, it'll tell you which sensor is unhappy.

Sensor 1: Either bad sensor or engine running poorly.

Sensor 2: Either bad sensor or the cat is not heating up properly.

Sensor 3: Either bad sensor or the cat is not burning up remaining fuel correctly.

From there you should be able to troubleshoot and fix the problem. Since sensors are 25$, I would start with those.


One last thing, did they shove something in your exhaust during the check? Ford's emission systems are ridiculously lenient, and often will not trigger sensor faults even if the cat is in shreds and missing most of its honeycomb. In that case, change your cats and forget about the rest of the system.

CarBridge is a tweak for jailbroken iPhones. It lets you run nearly any app over CarPlay. It also lets you adjust the number of icons on the CarPlay home screen. I just got it up and running tonight so I’m still playing around with it. I wasn’t able to get PS4 Remote Play working but Splashtop works perfectly so I can access my desktop PC from my car stereo, which is awesome. I'm totally going to Photoshop something using Sync 3 haha. YouTube was my primary reason for installing CarBridge but the Xfinity app and VLC also work great. Looking forward to being able to watch live TV and even recordings from my DVR while I’m stuck in traffic.

A few others I tried are weather radar, iMessages that let you actually see the messages, the camera app, and an OBDII app that communicates with my ELM327 Wi-Fi OBDII reader. Now that I know it works I’m going to choose an app that shows gauges (those all cost money) so I can see stuff like oil pressure, boost, voltage, etc. when I’m running the car hard. Oh, and of course, Apollo for Reddit works as it should.

All the apps perform quickly and the image actually looks pretty crisp and detailed in person. These pics aren't doing it justice (had to use my iPad) but I was really impressed by how sharp it was when I used 720 or 1080 resolution in YouTube. I also highly recommend this glass screen protector to improve the look and feel of the screen. It’s like a night and day difference vs the fingerprint magnet plastic factory touchscreen. Much less glare too.

The one downside I noticed is that Sync 3 doesn't support multi-touch but overall I’m really happy with the results. Well worth the $4.99 for CarBridge. Let me know if you can think of any other apps that would be fun to try.

Takes a couple of days of varied driving before this code goes away

u/tralce · 2 pointsr/s10

Your best bet is to get a code reader, if you don't already have one. Here is a cheap one on Amazon. Failing that, your nearest VIP or other auto shop will usually read the code for you for free.

Once you know the diagnostic code it's throwing, you'll have a better idea what happened.

I'm leaning toward it not being a frozen anything; if something froze in the injectors, you have a lot of water in your gas, which would cause problems even when it's not cold out.

Very often rough idle is caused by MAF and O2 sensors. You also might be having issues in the ignition system, so check your plugs, wires, and distributor.

Good luck, and please come back to post more question, or if you found the solution, post that.

u/Kadin2048 · 2 pointsr/nova

The answer to your question as-asked is that VA Tire for $114 is probably having a tech do a diagnostic and give you an estimate, which might or might not take a fair amount of time (some really generic codes, like an evap system one, can require a fair bit of testing to get down to the point where you can generate an estimate). Jiffy Lube is probably just scanning the code, which is only a few seconds of work, and if it happens to turn out to be something they can fix they'll offer to do it, but if it's not they're not going to go any further. JL is not exposing themselves to any risk of spending more than a couple of minutes, therefore they can offer that service for free. So that's the short answer.

I personally don't like JL (see my other comment if you care, it's sort of a YMMV situation), but there's nothing wrong with what they're offering. A free code scan like that -- which you can get at a lot of places, including most auto parts stores (or a buddy with an OBDII scanner, they are pretty cheap now) -- isn't a bad starting point if you've got a trouble light on the dash and need to pass emissions or something. Sometimes the code will tell you pretty much exactly what's going on and what needs to be done, and you can decide from there who you want to have fix it (or even DIY, if you're comfortable with whatever needs to be done). If the scan alone isn't conclusive, then I'd go to a real shop... and probably be prepared to pay a diagnostic fee if I have them diagnose the issue and don't have them then go and fix it; that seems only fair for their time.

Depending on what's going on that's prompting the question, you may want to ask or look at previous questions asking for recommendations of repair shops in N. VA... I don't have anything specifically against VA Tire, but I haven't heard anyone ever say that they were particularly awesome, either, and there are plenty of very well-regarded shops around who I'd probably go to first.

u/Drathus · 2 pointsr/homeautomation

You could try a bluetooth OBD2 dongle. Then pair it to something like a Raspberry Pi inside which could connect to the OBD2, monitor data for engine on, and open the garage door if it's closed and the car is on.

I'd be curious to see what kind of lag there is in the cycle if it's going from a cold disconnect to garage door open, but it should be doable.

Not that I'd risk it myself, but I'm paranoid enough about CO that I've been pondering building an exhaust snorkel for my garage for during winter. =P

u/ThrottleMunky · 2 pointsr/CarAV

>All my LED's are done solid,

Solid? The problem with LEDs is that the computer expects a certain amount of draw and when the draw is low it thinks there is a bulb burned out and you typically get 'fast blink' and doesn't have anything to do with the connection being solid or not. The only way to fix this(properly) is to buy a flasher relay designed for LEDs and these don't work in every vehicle or install resistors(bad way) to bring the draw back up and defeating the purpose of LEDs. So called ODB safe LEDs just have a resistor added into the bulb which makes them very hot and prone to failure/melting lenses. In any case, LED bulbs will not create the problem you are seeing. You are on the right track with the battery sensing circuit. It lessens the life of batteries to overcharge them on a constant basis so newer cars will lower the charge voltage when the battery doesn't need the extra energy in order to extend their life. If you connected an ODB2 sensor, like this one, you will see that even though the battery/amp are only seeing 12v, the ODB2 system will still be seeing 14v(or whatever the alt is producing) and the voltage is being stepped down for battery charging purposes.

u/Okey_Cokey · 2 pointsr/FordFocus

You can search this site, or LKQ's online website to find a Sync 3 Screen and APIM. Junkyards sell them as separate units and for a lot more, so I recommend LKQ's site first; they usually sell them together for one low price. Make sure it is Sync 3 (2016+ Focus) and not Sync 2.


Next, you'll need a new media hub (Part # HU5Z-19A387-A) for Android Auto and Apply CarPlay to work, as well as an adapter plate and wiring harness from 4Dtech. When you have all of these, you can plug the Sync 3 system in and it will work on its own.


You can choose to leave it as such and deal with some of the small bugs it may have, or you can reprogram it to work with your vehicle options. 2012 is the only year where you need to program the APIM for it to recognize the steering wheel controls. To program, you will need this OBDII reader and the FORscan program with a free extended license. With FORscan, you can flash the APIM to enable or disable settings such as the back-up camera--if you do not have one, climate control repeater (where the temperature displays on the sceen), colors and themes, steering wheel controls, etc. Do NOT play around with the hex codes too much or you may brick your APIM. I have a hex code master list I can forward to you via email if you decide to undergo the project. It sounds harder than it actually is. I was able to have it installed and programmed in about an hour.

Sorry, yes, "ELM327". I bought this one - it's for sale from the same seller currently as well (OHP Tools). Apparently there are a lot of knock-offs or cheap versions that don't always work properly but this one seems to be a good version. I've had no issues.

u/cheated_in_math · 2 pointsr/videos
u/Tangent_ · 2 pointsr/BMW

Yeah, 87,000 is close enough that it wouldn't hurt to do the spark plugs now. With that bad vibration/check engine light it's hard to say what might have caused it.

Over the years I've had a few occasions where I've had something similar, but it's been so few and far between that it's usually easiest to chalk up to a computer glitch that's resolved by the restart and not something with a mechanical cause. If it happens again try to read the code. An inexpensive code reading solution is any cheap ELM327 bluetooth OBD II adapter from Amazon (around $10) and the Torque app for an Android phone. A more powerful solution that can give you BMW specific codes and also lets you do lots of coding to customize features in your car is to buy the Carly adapter (Android adapter, iOS adapter) and their app.

They're all DIYable, some with a higher skill level than others of course. If you have a place to do it and can read and follow instructions you can do any job and save lots of money even if you need to buy the tools first. Lots of people are intimidated by it but with just a bit of care it's something anyone can handle. One of the big things I follow that solves the biggest problems new DIYers face is using a torque wrench when tightening fasteners. If you do that you won't need to worry about overtightening anything and breaking off a bolt, or undertightening and having it come out. If you aren't comfortable with it or you can't afford to take the time to do it yourself, a good independent shop will be a much better bet than the dealership.

Here are DIYs for the ones I mentioned:

Spark Plugs (Easy)

Ignition coil removal - Part of spark plug DIY.

Valve cover gasket (Challenging)

Motor Mount (Moderate challenge, but more in the getting to bolts way than complexity) Couldn't find a Youtube video I liked, this has lots of pictures and good step-by-step though. The only thing I would change from their DIY is to use this or similar engine support bar rather than supporting the engine from below.

I'd say the spark plugs and coils are absolutely something you can do yourself but read and watch the DIYs on the motor mounts and VCG carefully before deciding to tackle that. If you see no oil down in the spark plug you likely don't need the VCG anyway, and the motor mounts would just cause you to feel the misfires more and you can actually see it on the tach.

If you go to Amazon and type in "OBD2 scanner" you'll get tons of different results. They have all kinds of scan tools nowadays. The more expensive ones with really advanced features can even cost thousands of dollars and look like freaking Ipads!

But a basic $15 scanner like this is still great to have. It's super simple to use. You plug it into your cars OBDII port (located in the driver's side footwell, usually somewhere near the hood release latch.) Then flip your key to the "on" position (don't turn the engine on, just turn on the ignition such that you can use the car's accessories and unlock the steering column.)

From there you can pull codes as well as erase them. The scanner will come with more detailed instructions but it's pretty self-explanatory. The thing only has 2 buttons so if you can use a computer or cell phone it shouldn't be a challenge.

u/GotMyOrangeCrush · 2 pointsr/MechanicAdvice

Any auto parts store will scan your stored DTCs for free. Step #1 is to determine what DTCs are stored.

If your CEL (check engine light) has been on, then there are DTCs stored. If your CEL was flashing, that means the engine was misfiring, big time. If your CEL is flashing there's a risk of doing engine and/or cat damage ($$$).

If you are determined to troubleshoot and fix it yourself, then a scan tool that does live data will show you what's wrong.

In general, a scan tool will tell you about all your sensors, or TPS (throttle position sensor) O2 sensor, ECT (engine coolant temp), MAP (manifold absolute pressure), etc. And 'live data' means you can see what they are doing when the engine is misfiring.

There are two ways to get a scanner, either a dedicated scanner or with a smarphone app.

  1. Dedicated scanner: Innova makes some easy to use scan tools, about $120 for a Innova 3040e.

  2. Scanner APP: Most scanner 'apps' are $5 and a bluetooth OBDII gizmo is about $20.

Sometimes you can rent/borrow them from AutoZone or Advance Auto Parts but I'd call ahead before making the trip over there. Obviously getting the car there won't be easy.

It could be just a loose sensor cable, vacuum hose or pinched fuel line from the whack your car got. Code reader will give you a really good place to start. Hopefully it's something simple.

u/spunker88 · 2 pointsr/AndroidQuestions

You buy one of these bluetooth OBDII readers and plug it into the port on your car. All cars 1996 and newer have this port. Download the app Torque and connect your phone to the bluetooth reader. You can then view all sorts of data from your car computer and retrieve any check engine codes which you can look up online. You can also clear the code which will turn off the check engine light.
This was a lifesaver for me back in college. I was driving around a car that needed some exhaust work but didn't really have much money to put in it. By checking the code I could tell if it had a problem that needed to be addressed or if it was just something to do with the exhaust system.

This one coupled with the torque pro app ($5) is a popular yet affordable choice:

u/4benny2lava0 · 2 pointsr/internetparents

this guy explains how to look at a car and as a car guy I can say he is very through. Now would be a good time to invest in a OBD (on board diagnostic code reader. This is the one I use. I do not know about any that work for iPhone; if you need; pm me and I can look into finding you one that does not suck.

If you put in your due diligence you know if it can pass inspection and if not what it would take. This all affects your bargaining chips. Do not be afraid of offending the seller with your offer or how they might react. It is your money and you are going to make sure every dollar takes you as far as it can.

Since you do not know how to work on cars I suggest sticking to american and Japanese cars. European cars are designed differently; require different tools and IMO harder to work on. (I am sure they can say the same about american cars)

Anything built before the 08 financial crash stick to Japanese. There are a handful of good american SUV's made before then like the Jeep Cherokee; the one with the 4.0 inline 6. As for Japanese; toyota, honda, & mitsubishi are your best bets.

You are looking not only for something reliable; but something that is not going to cost an arm and a leg and require you to move a mountain trying to fix it. All cars will give you problems. I can fix just about anything outside of the engine and transmission; so that affects what I will buy. I can save a lot of money buying something that needs a days work rather than something working flawlessly right now. When you get in and drive it; it had better feel like the engine and transmission are working flawlessly. Any jerkieness, gear slippage, anything other than that engine and transmission running smooth as butter; walk away. There is nothing cheap and easy about internal engine and transmission work.

One more thing; decide whether you are buying something you want to trade in sell later or something you will run until it is dead. This affects your decision on what to buy right now.

You can call an insurance company and get a ballpark figure of what the car you are looking at will cost. My '04 MDX will cost about the same as the same year Mercedes e320 or toyota 4runner.

So you did your homework and decided what you are buying.

The owner signs the title over to you. You get the car insured, then you take the insurance and title to the local DMV and they will give you a temporary registration and a temporary license plate. Some states will give you a permanent license plate right there.

You take your plate and head back to the car; you put the plate on and start driving. You will probably need to get the car inspected. You head on over to the local inspection station and let them do their thing. If you fail they will tell you exactly why so you know what to do.

If you pass; they give you a sheet of paper saying that you did and you take that back to the DMV and they will issue you a permanent registration.

You can goto an autoparts store and they will read the code for free.

Buy a bluetooth OBD adapter that works with FORScan. This software has ALOT of power and acts like the dealer tools. I reprogrammed my ABS module when I rebuilt my 2014 (replaced module with a used one). Mazda themselves couldnt do it because their software can only writes the software but does not re-write over a module with software already on it.

Very useful tool for check engine lights and general diagnostics. Makes an incredible amount of data available to the home mechanic.

u/bovinitysupreme · 2 pointsr/MechanicAdvice

I'm not /u/gingican but I can provide the comparison:

  1. Generic one that looks like this: -- mine was from Harbor Freight (they don't have it anymore) and was orange but otherwise identical. Fine for pulling standard codes and resetting Check Engine Light.

  2. Scangauge II -- mainly used as a gauge but good for pulling/resetting basic codes and getting freeze frame data. Obviously, can provide a bunch of data (as intended for daily gauge use). With a lot of work (programming XGauge codes) it could get a little more data too.

  3. BAFX bluetooth OBD2 tool is nice. It's just hardware, it works great, but what's really nice is Torque. Torque can store/export sensor data, integrate with GPS data, display all manner of gauges and graphs, etc. My only complaint is I can't access ABS codes (specifically on my GM). Also, bluetooth itself is nice, the device is easily plugged in and no fooling with wires, and I can interface with the phone that I already carry anyway.

u/WebMaka · 2 pointsr/MechanicAdvice

For best (read: accurate) results, make sure your dongle uses a genuine up-to-date ELM327 and not a bootleg knockoff running outdated firmware. (A Chinese company got hold of an older version that didn't have the security bits set right and did a ROM dump to get some of the firmware, which has gone into mass reproduction for the cheap ELM knockoffs. The real ELM, OTOH, has had several firmware revisions since then and isn't missing entire blocks of program code.)

This is the one I have as a spare/quick-and-dirty code checker. It works well, it's pretty accurate compared to my more expensive scanners, and it's a legit ELM327 running new firmware.


There are also new competitors to the ELM327, namely the STN1110, STN1170, STN2120, which claim to offer faster performance and a larger number of supported protocols. However, I have no experience with these as only a scant handful of dongles are using them.

I had the same lights and the car was running fine but I had the p0a93 which is a bad inverter pump generally (it's a cheap $60 for parts and coooant fix).

So I got the wires resoldered up and everything was working again.

If you just need to clear codes then disconnecting and reconnecting the battery will do that for you. If you want a code reader anyway then I bought this code reader that has worked well with the Torque app. Only complaint is that it only updates about every second so horsepower, torque, and 0-60 don't get good readings. No idea if it is the dongle, app, or just what OBDII can do but something to be aware of.

u/sparkie172 · 2 pointsr/subaru

You can go to autozone or wherever they check for you then look up online as code is generic. Each brand has their own specific meaning for the code. Before my cobb I used a Bluetooth obd2 reader 20$ online then used torque app from Android store free version to check and clear codes. It also does some pretty cool stuff for the paid version. The obd2 reader is small which I liked. I had 1 like this.

u/iHateMyUserName2 · 2 pointsr/GolfGTI

To go with the other reply from the Ross-Tech (worker?/user?/employee?) you can use it for that but there's a delay in the reading from a half second to a full second. It's not really all that noticeable unless you're kind of looking for the delay, but I think you'd be much happier with a boost pod.

Edit: also, if you're jailbroken you can use the bluetooth version of the transmitter but if you aren't jailbroken then you have to use the wifi version. Now I've not used the wifi, so I can't speak for how it performs, but I'd imagine that it would actually be better than bluetooth because of the latency (delay) associated with bluetooth as opposed to wifi.

u/OnTheClock_Slackin · 2 pointsr/JeepRenegade

Don;t ignore an engine light, even if it goes away. You can stop by a locak auto parts store (auto zone, reilleys, etc) and they will scan for free in most states. It could be as simple as a loose gas cap or it could be a bigger problem, but if the light is coming on at all there is definitely something wrong. Maybe just a flukey sensor, but if the sensor is flukey then it's not really giving you truthful information about what it should be monitoring. You could also buy an ODB2 bluetiooth scanner tool on amazon for like $18, plug it in, connect to your phone and you can pull the codes yourself to see whats wrong.

u/dreamz7013 · 2 pointsr/Dallas

Like /u/rahtx said, Autozone can help you pull the error code. You can buy this from Amazon and be able to do same thing

u/blandreth94 · 2 pointsr/ToyotaTacoma

This method worked great for my 2015 AC. It should work on 2012ish+ tacos.

You will need a bluetooth or USB OBD adapter. You can get them fairly cheap on amazon however the standard one seems to be the BAFX tool for bluetooth. I then used a simple OBD2 Terminal app (for android, either this one or this one, can't remember I used) to send the commands.

Just be extra careful and make sure you type the commands in exactly as shown.

I am not liable for anything ever.

Edit: FYI: No matter the method, any changes of this nature are automatically reverted when the battery is disconnected.

u/on_the_nightshift · 2 pointsr/saab

My son's first car, bought this year, is an '06 9-3 2.0T as well!

These cars like to throw codes/check engine lights (CELs). Do yourself a favor and order one of these and buy "Torque Pro" from the Google Play/Apple app store. You'll have less than $30 in it all together, and it gives you some nice tools besides just the ability to read and reset codes.

As someone else said, google for any issues you have, they have likely been answered. Might as well make an account on saabcentral and saabnet. Lots of good info and knowledgeable people on those sites.

When (not if) you have to replace the coils, make sure you buy the right ones. ONLY the ones with the correct markings will work correctly. There are LOTS on the market that say they are correct, but aren't. Here's one that I know works (my son's car has 4 new ones). If you sign up for Advance's "SpeedPerks" membership (free), you'll get discounts, money back, etc. Order this stuff online, even if you're picking it up in store. Their website sometimes even has $40 off $100! Usually at least 20-30% off.

Anyways, I hope this helps, and feel free to ask any questions!

u/Chalmun · 2 pointsr/Cartalk

Definitely. I have this one with Torque and it works great. There are different ones and prices (I got this one for ~$14) The scanners you have just give you an error code, these give you so much more information. Plus the live data readouts with the engine running are just fun to watch.

u/MyD0gNeedsaJ0b · 2 pointsr/JeepRenegade

Get one of these. Download an OBD app. The apps I've used will bring up specific codes and read out faults.

I will add that this may not be rock solid advice as I've heard of some newer vehicles freaking out and requiring their software to be reinstalled. If it Renegade, I wouldn't hesitate to give it a shot in your circumstances.

You may be thinking "This isn't good advice because I want to know now" and don't want to wait for shipping. I still recommend ordering one even if you explore other avenues. I bought this exact unit and it has paid for itself multiple times just in fuel savings of driving to a AutoZone/dealership.

Wish you luck and hope the best for you and your Renegade!

u/bmorocks · 2 pointsr/MechanicAdvice

I agree here. I bought my Bluetooth dongle from Amazon and use the Torque app, which is available only for Android. I do use the paid version, however, and it works wonderfully.

Beware of some of the cheap-o Bluetooth adapters on eBay as some might not be able to work with the CANBUS protocol. Just make sure the eBay seller has a decent return policy if you do buy on there.

The app + Bluetooth adapter combination works great for me. It makes it easy to look up codes and save them. If you want more information for a code than just a quick one line description, the app takes you to a website that displays more information about it. It's pretty slick, cheap, and more handy than some of the regular OBDII scanners with the built-in screens.

u/themangeraaad · 2 pointsr/motorcycles

For anyone looking to do this be sure to read the reviews. I know that some of the cheap Bluetooth adapters don't work with every make of car (or I've read that this is the case, at least with fords).

That being said there are some that work pretty universally... Just do some research before clicking "buy" on the first adapter you find.

Edit - Just got back to my computer and could look it up. This is the specific Bluetooth OBDII adapter I've got which so far has worked fine on Ford, GM, Dodge (Jeep), VW, and probably a couple other makes:

I was gonna ask what brand but you said you've tried multiple ones ("blue EBay"...I'm guessing a generic, no-brand). Are they all those cheap adapters (sub $10) that seem to often give users problems? Torque's dev cautioned against them but mainly because they didn't always play nice with certain vehicle manufacturers iirc.

I'm stumped, sounds like you've done all the obvious troubleshooting to verify it's not the adapter itself unless all the adapters you tried have the same problem (why I asked which ones).

There should be a stored code from the airbag light which would help with figuring out what's causing it. You won't get it with a scanner that only pulls CEL codes. A dealer could get it, or you could something like this. I have one and I was able to get ABS codes from it.

Good luck with the blend doors. I almost wish our Jeeps had the Takata airbag issue because then I'd have the dealer replace the blend doors, heater core, and a/c evap while they had the dash off to do the airbags. Just so I wouldn't have to worry about them.

As for the shifting, sounds like a clutch issue.

u/guitarinjustin · 2 pointsr/cars

If you have a smartphone I would recommend a wireless OBII scanner!. I can't speak for this particular model, but mostly they're all cheap and do an OK job.

I would get some sort of universal emergency kit, such as a JustinCase! or something similar. You will probably never use it, but it is great to have when you do need it. It's also small and compact so it won't take up much space. You can also fit a few more basic tools in this bag if you wished.

I would also recommend having an envelope with your insurance, registration, and possibly a photocopy of your license(I forget my wallet often and it's nice to have a copy just in case). You can laminate these if you so wish. You wont lose your important stuff and it wont get ruined either!

I would also recommend doing your own maintenance on your car. You get to learn a little more how it works and best of all you save money! Youtube has many videos on basic car maintenance. If you ever do more complex work I would recommend picking up a Haynes or Chilton repair manual for your vehicle.

I went from literally knowing nothing about cars to rebuilding engines. I'm not a mechanic and don't make any money from this. I just value being able to fix something myself. It takes time, but a great way to get started is to learn how engines work on youtube or whatever. Once you have a general understanding of how an engine works you can diagnose problems much more easily.

All cars from the mid-90s and up have OBD 2. All the device does is essentially act as a translator to the car's OBD 2 and your device.®-Wireless-Scanner-Adapter-iPhone/dp/B00B3K2X4M

You can use either a laptop or smartphone/tablet. Don't know if that specific reader above will work, but that's the type of device.

Edit: if you do go the smartphone/tablet route it goes without saying that the included CD won't work. You need to download an OBD 2 reader app. A good one is DashCommand, and it's $10 in the App Store.

Edit 2: Here it is in action. 2 minutes, top.

Don't let the wires deter you. It looks like he has that permanently mounted and those are power and audio cables. The OBD reader is still operating wirelessly.

I hear ya, but I think I covered this angle in my OP.

I've got a lot more experience as a mechanic than as a cellular salesman, what you just said there is the sort of horseshit sales pitch that's as shallow as 'pay us extra, cuz money' that corporate is always trying to push. I don't blame you, and I feel a little bad for telling you this because disabusing you of the nonsense that they've fed you will make your job harder, but there's nearly 0 real utility to it that can't be done with the phone people are already paying for.. which is why carriers love to sell them, it's high margin value added frivolousness.

This is a better diagnostic tool than any connected hokum being sold by carriers and it's ~$10. With a free or ~$5 app, there's a lot of information and help at your fingertips that can be read or shared.

>You may not want a tablet with a data plan, but a single mom without WiFi may want to give her kids one, or a college kid who needs something to take notes or draw on the go, small time YouTuber, etc.

Like I said, I don't represent everyone, but a lot of that doesn't resemble what you find in many areas. YMMV, but it can be a tall order and I don't feel like OP is lying to us.

In the interim, if you are so inclined, you could buy a cheaper OBDII sensor with an app on your phone that will allow you to monitor the temps.

One like this:

Though that is for android phones, I know Iphones are a little more picky.

It connects via bluetooth and shows you all the measurements by your ECM, it also reads and clears check engine codes.

I've owned two wifi models, a chinese one and a good plx devices kiwi and the first was maddening and rarely worked correctly, and the second sometimes required extra resetting.

now that ios supports bluetooth, its all easy peasy.

You need an iphone that supports bluetooth 4.0.

For codes yourself a favor spend $20 on this OBD II Reader. There is a free app and you don't have to go down to borrow an OBD II from the auto parts store, it's super slick, tells you fuel trims, throttle position, a bunch of other things in real time, and allows you to clear fault codes.

u/nostinkinbadges · 2 pointsr/CherokeeXJ

Look at this one:

You have 4 options for that product, so you get to decide whether you need WiFi for iPhone, or Bluetooth for Android. WiFi will actually work with Android, but not the other way around. I personally prefer the BT+Android because that still leaves you connected to the data network (WiFi or LTE). To use WiFi with iPhone you have to do ad-hoc network connection to the OBD2 interface, which cuts you off from doing any kind of Google or forum search when you are connected.

Edit: my bad, only 3 options for the interface, the fourth is the extension cable. This adapter is small enough that you will not notice it getting in the way, unlike the one I had before it. The low-power standby version is probably there because it is easy to forget the thing is plugged in, and after a few days it can mooch enough juice from your battery to give you trouble. WiFi is really bad about that, BT not as much.

u/jakjar · 2 pointsr/Volkswagen

Agreed, but FYI buying a Carista and changing the throttle coding from "Gradual" to "Direct Throttle Response" helped a TOOOOON with making acceleration more linear. Unfortunately it sounds like "turbo lag" is a very real thing on a lot of new cars out there, though.

u/patriotdad1776 · 2 pointsr/jailbreak

I have an XR on 12.4
I use this to scan vehicle codes all day. You can't use a cheap ELM 327 blue android one, gotta use a newer one like this.

u/RW63 · 2 pointsr/prius

I have a Carista and didn't use my free trial until there was a code I really wanted to get more info about. (It gives "regular" codes without a subscription, but some of the more Toyota-specific, you have to get a subscription for it to display the last couple of digits, but it comes with a month free trial that you activate when you need it. Some of the other scanners may be different, but based upon a recommendation, it's the one I chose)

There are two batteries in a Prius. There's a 12v that boots the computer and whatnot. If that hasn't been replaced, it may be soon due (and replacing it could possibly get you a little better gas mileage), but it's only a couple of hundred bucks from an auto parts store and you may not need to replace it any time soon.

There's also the big hybrid or traction battery for the electric motor. ChrisFix has an excellent video about replacing it yourself, if that's something you'd like to do. Everybody will tell you it's cheaper to buy one from someone other than a dealer, but luckily I haven't had to do it and my older Prius has around 197k.

Of course, some people have had to replace them much earlier -- this forum or could be a source of more info -- but I'd say the majority of people have had not. I've noticed a lot of Prii on the market around 116k to 130k. I believe it's because the battery warranty runs out at 100k, everywhere but California, where they require the same battery to be warrantied for 150k. And again, knock on wood, I have one pushing 200k.

u/omega884 · 2 pointsr/Miata

Yeah, so this sounds a lot like my 99. Never threw a code for the bad O2 sensor, but would throw the cat code. You could be getting the cat code either because your cat is actually shot (although I'm not sure if that would be the cause of the bucking when cold) or because the front (and possibly rear) O2 sensors are shot, causing the computer to think your cat is shot. If you were having misfires, it's definitely possible your front O2 sensor is dying. An OBD-II sensor will be really helpful here if you don't want to pay a mechanic to troubleshoot it. I use this one and while their app works, I prefer OBD Fusion, which also has an O2 sensors monitor that will show you the self test information from the computer for those as well.

u/theservman · 2 pointsr/Subaru_Crosstrek

u/fangorn0 · 2 pointsr/nissanfrontier

You can get a bluetooth-enabled OBD II scanner on Amazon, like this one, and then use a smartphone app like Torque Pro (Android) or OBD Fusion (iOS) to gain access to all sorts of information that the computer has but isn't displayed.

This car has ~140k miles and the majority of things under the hood seem to be original. The last owner kept a pretty good record of routine maintenance. They were not the type to take the car to the dealership for repairs or maintenance, but everything that I have changed lately (plugs, wires, PCV valve, serpentine belt) were all Motorcraft, which makes me think that most of it is original.

I did order an OBDII scan tool which should be here in a couple days, so hopefully that will be of some help. Most of my previous cars were older and I didn't have any use for that sort of thing.

I suspect the app is the less of your worries - just find one that works on your OS. The hardware is the bigger concern. I bought this one a few months ago:

... and it's been A-OK in both my '04 Saab 9-3 and my '05 Subaru Outback, running the free version of Torque on a Note 3/Android. The whole reason I bought it in the first place is that I had a check engine light for no obvious reason on the Saab, and neither of the first two auto parts stores I took it to were able to even get a code from it when they gave me the 'free OBDII read' try - both got connection errors. (So I ended up paying a garage to do some diagnostics, and it turned out the actual error was a single cylinder misfire - no big deal, and not worth the $ it cost to find it out.) Point being, the BAFX never had a problem getting a read on the Saab where two different models of wired readers used by professional auto parts stores failed.

Using it with the myGreenVolt works without any issues. There's a ton of similar products on amazon that look like the same thing but re-labelled as iphone compatible.

I started off buying a cheap $8 one that didn't work at all and had to return, so I would suggest looking at something in the $20 range like this one. The only downside is that my knees are constantly bumping into it when I drive, because of how much it sticks out under the steering wheel.

u/betterusername · 1 pointr/Audi

Ross tech makes a great cable with software (Windows) included, but they go from $$$ to $$$$$. You can buy a cheap OBDII bluetooth interface like this one (works pretty well) and an app like Torque pro or Carista (expensive monthly subscription required for anything beyond actually OBD2 protocol codes), but it's not as full featured as Ross Tech's.

You can also look on something like AudiZine for someone near you, or take it to any Audi specialty shop.

>Some Chinese piece, not sure myself

There is your number one problem. Should have gotten a decent OBD2 reader. I spent $25 on the bafx one, and skipped the cheap ELM127 ones, and I am happy I did. This looks more like an issue with the reader itself not being able to interpret the readout correctly(like from a wrong interface spec). Have you checked "hide unsupported sensors" in the options of Torque? Are there any other fault codes besides P0420, and what car is it? Also, with the adapter plugged in, go to the "adapter status" page, and scroll down to see what sensors that the computer reports are supported. see what those "bank1" sensors relate to.

Edit: they usually related to the pre and post cat O2 sensors, now that I think about it. See my other post as well.

I'm not familiar with wireless scanners but I would be curious if the added cost is worth the convenience.

Poking around on Amazon some more might find you a better price tool with less features.

If you don't mind the plug-in tools I would highly recommend - I bought one to troubleshoot a recurring CEL and was pretty happy with the price/ease of use. The Autel tool only reads and clears codes; you'll have to google the actual code to figure out what it is. Good luck!

u/SilverHerfer · 1 pointr/MechanicAdvice

Speaking as a non professional, who was once in your position, I would do a couple of things:

Buy the Chilton or Haynes manual for your car. Some will buy the actual shop manual from the factory but it is more expensive.

Check to see if there is an on line owners forum for your specific make and model. I belong to at least 1 owners group for each of my cars. There is little you will face that someone there hasn't seen, fixed, and provided details with pictures. The older the car, the more likely someone has already figured it out.

This sub. You've already found it so that's a good start.

YouTube. Full of instructions and videos on how to fix and replace stuff. You'll find just about everything there. A lot of garages will put out some really professional looking video's in hopes you'll buy the parts from them. I learned how to replace the control arms, ball joints, and end links on my Ranger and Explorer, the struts on my Toyota Previa, and the motor mounts on my Focus, all through YouTube videos.

I also couldn't live without a good OBDII reader. I use the BlueDriver (but there are others like it). For every code it finds, it gives you access to a pre written report, by ASE certified mechanics, on the top reasons for and best potential fixes of, that code.

And most importantly, you need a shitty car to work on. Mine was an old Chrysler also.

I purchased a OBDII Scan Tool and check the system every so often to see if any new issues come up. Now that I have the tool the dealership will no longer be able to fool me by resetting the system.

I was fortunate to have an opportunity to learn how to work on cars when I was younger. While I never had any desire to be a full time mechanic, I hate paying shops more. Newer cars while complex, they still can be done by the DIY mechanic. A good two way scanner will go a long ways. For $100, I recommend the blue driver as a good one way scanner.

u/jewski1 · 1 pointr/MechanicAdvice

I’m currently in a similar situation with a car worth less (and we still owe more on the loan) than what the potential repair is. By some dumb luck I had the thought to look through the paperwork from when my husband bought the car and he had freaking bought mechanical breakdown coverage!!! So I’m breathing a sigh of relief atm. But as for you, the code thrown by the car is not always indicative of what exactly is wrong. For example my car was throwing an engine code (p0172) and multiple engine cylinders misfiring, but in actuality the turbocharger had gone bad (still an expensive fix, but less than an engine repair). Trans tune and slip fluid, may help in the immediate future, but after that the problem will still persist, its a temporary solution if it even works. To clear the codes you can buy your own OBDII reader and just plug it into the car and clear the codes if you really wish. This one I know for a fact allows you to clear codes, but you might be able to shop around and find another cheaper one that will suffice. As a suggestion, some mechanics will buy cars that need work because they are able to fix them and then sell them for more money. It’s just an option and would put some money in your pocket to buy a new car if you can’t afford this repair.

Edit- wanted to add to the part about codes not being exactly what’s wrong. They still correlate to the mechanical failure. The engine code of p0172 is that the system is too rich in bank 1. This means not enough air and too much fuel is flowing into the combustion chambers. So it makes sense that since the turbo is not functioning, enough air would not be getting mixed in with the fuel.

Edit 2- hastily wrote my first edit and apparently irked some people off :) fixed my mistake.

u/johnzabroski · 1 pointr/csharp

I know that's how you feel, but what would you do if you didn't feel that way?

I'd be interested in helping you, if you're interested in pursuing this (I even have a potential business idea on how I'd use this data). Certain luxury manufacturers also let you use the ODB interface to manage advanced settings that are otherwise unavailable.

I searched GitHub for "ODBLink" (a popular scanner tool) to see what scripts/programs users have wrote, and found a Python program with a reference to a useful spreadsheet for how we could get started:

# Thanks to Brian Batista for the use of the CANBUS guide spreadsheet.

So, I searched Google for "canbus spreadsheet", and found this Google Spreadsheet: CANBUS Fleunze SE (top non-ad search result)

Similarly, for Ford Mustang cars, I did some digging and found Ford has opensourced their OpenXC tool:

>While UDS is a closed protocol, researchers at Ford have been working on creating an open platform for interfacing with vehicles. The result is the OpenXC Platform. OpenXC provides a protocol to read data from Ford vehicles over CAN.
>To use it, you’ll need a vehicle interface. A chipKIT can be used with Ford’s open source firmware. Alternatively, you can buy a prebuilt solution from CrossChasm. Once the vehicle interface is up and running, you can access data from the Android and Python APIs. We’ve featured a few OpenXC hacks on Hackaday in the past.
>It’s great to see an automotive manufacturer embracing open source, and hopefully Ford continues to work on the platform. That being said, the OpenXC protocol is read only, and limited to a fairly small set of messages.

The conventional wisdom on is "If you're working on a Lexus or Toyota, nothing can beat Toyota Techstream." However, Carista comes close. Carista focuses on hidden features ("dealer-only settings") like daytime running lights. They provide similar "dealer-only settings" for other makes and models.

I personally use an expensive ODB-II reader, because:

    >What are ENHANCED diagnostics?
    >All vehicles with an OBD2 port are required to output basic information when the Check Engine Light comes on. However, a lot of important information (such as ABS, Airbag, Climate Control, etc.) is left behind by other scan tools and code readers. [...] BlueDriver gives you the complete set of diagnostics on a wide range of manufacturers.

    However, the downside to BlueDriver is:

  1. Earlier versions of BlueDriver didn't require a PIN for the Software to authenticate with the Hardware component, so anybody could intercept your Bluetooth traffic and execute a man-in-the-middle attack and potentially kill you. (Read: Really, really don't buy an old, used version of BlueDriver Sensor). Note: This problem only exists in Bluetooth-based ODB-II Sensors.

    >Bluetooth pairing is incredibly simple — sometimes too simple for its own good. Without a four-digit PIN to offer a bare minimum of protection, anyone within a 30-foot range could connect to BlueDriver dongle. If the dongle is not currently connected to a phone, the process will be trivial, and even if the dongle is connected, it's sometimes possible to prioritize a new connection over an existing one.

  2. BlueDriver Sensor (Hardware) only works with the BlueDriver App (Software). I haven't tried snooping on their bluetooth data stream, but I suspect there is an authentication token the Software sends to the Hardware to allow bidirectional communication over bluetooth.
  3. If you're looking for an ODB-II reader to bring to salvage/auction, you might prefer one with a dongle, as it doesn't require a pairing step and will begin reading codes immediately.

    In terms of "fun projects", I was thinking it'd be cool to use ODB-II Mode 6 and visualize, in real-time, Scotty Kilmer's "How to Get Your Car to Pass the Emissions Test (Life Hack)".
u/onrivertime · 1 pointr/Jeeps

These lights should be throwing an OBSII code. Have you had the codes read? Ideally, get it read with a reader that outputs the enhanced codes (ABS, AC, etc.) You can do it yourself with one of these (and mine has paid for itself x 8 so far). Faulty wheel speed sensors can cause all sorts of problems, for example

I'd be nice to configure it to go directly to the Torque app, but unfortunately, I have not found a way to do that with the MeMOPad. It'd probably be possible if it were rooted, but I haven't found a root method for it yet.

u/Faptain_Hand_Solo · 1 pointr/Nexus7

Here's the diagram I made up when I was doing the wiring

It wasn't too hard. I basically bought the plug for my car's existing wiring harness and wired the amp to that, used RCA cables to hook the amp ( up to the DAC (

On the other side, I got this cable: and cut off the male USB end, which I wired to a step-down ( on one side and the 12v switched power on the other side. Then I just plugged in the tablet to the micro USB and the DAC to the female USB.

I don't have any pictures of the piece of wood method, but basically, once I pulled out my old headunit, there was a hole in the dash. I stuck the amp and DAC into the hole and cut a piece of wood big enough to cover the hole with a hole through it for the power wire to pass through for the tablet. The tablet itself is sandwiched between that piece of wood and the plastic bevel of the dash with a bit of foam padding.

I'm not a hardware hacker, and had never done any car audio, and I had no problems figuring it out. (though I did kill my battery a couple tiems because I had the amp hooked up to the regular 12V line instead of the switched line, so it stayed on and drained the battery till I got that sorted)

I didn't bother with FM radio since I never listened to it anyway. I can't say I regret it, though I do wish that somewhere in there, I had an aux line so I could hook up a phone easily, but that's only so my wife could play stuff off of her iPhone.

Night driving is fine, but that might depend on your car. I just use the auto brightness, and I have a solid black background for the tablet, so if it's too bright, I can just minimize the app, though I don't usually have to do that. During the day, it's bright enough to see fine, but that may depend on your car layout.. in mine, there's no glare because the screen is vertical in the center of the dash.

Finally, I also have a blutooth OBD2 reader ( hooked up which displays some gauges for stuff like MAF, RPMs, Gas usage, etc.

There is no way to speculate about either of them without actually looking at the car. If you can call the dealer and get them to post a picture of the charging port, that's the best way. And whatever you do, make sure to double-check it yourself before signing anything.

Be wary of the really inexpensive ones. A lot of manufacturers have been keeping the model# and Amazon listing the same, but changing to a cheaper, less compatible chipset. In your link, people in 2015 and earlier say it work with Leaf. Some from in 2016-2018 say it doesn't.

Clean your O2 and MAP sensor. Next guess would be something related to the fuel/air system. Buy an OBDII reader off amazon for a few bucks and read the code when you get it next. You can leave these plugged in and access it on the side of the road through your phone.

Last guess would be limp mode, but I really doubt it and if I'm not mistaken this limits you to 4500.

  • edit - limp mode is 3000. You're in limp mode. Check your coolant level and if it's low, get a compression test and scope the cylinders.

  • Check all wiring harness connections for a solid connection. Also check that sensors are free of carbon buildup.

  • Check the engine oil level

  • Make sure to always tighten the gas cap 3 clicks. This can throw the car in limp if it is not tightened correctly.

I use an OTG adapter for the OBD2-USB cable, that website sells them for $5 extra (Amazon also has this Carly kit: but I've only bought the one from the site I linked you too, and I know for sure they test them before they ship it). It allows you to plug that cable into a tablet or phone with micro-USB. I think it's Android only, so it won't work with an iPhone. You plug in the cable to the obd2 port, then plug it into your android device, then hit connect in the app.

I think I had saved this one: -- I had another Bluetooth dongle I used to use with another app but I misplaced it during a move a while back. That one worked with an app called Dashcommander but not sure about Carly. I ended up getting the cable instead of another one because I wasn't sure if the MHD app would work via Bluetooth.

u/wegngis · 1 pointr/Cartalk

It's super easy to change an O2 sensor, but make sure the sensor is actually bad. Often times people will change the sensor because it's giving a bad reading, but in reality the sensor is just fine and it's reporting a faulty condition elsewhere. I'd suggest getting your own code reader and investigate.

u/martianyam · 1 pointr/vandwellers

Nothing crazy really... You would just have to maintain the vehicle on a different schedule meaning oil changes and filter changes should be done sooner than usual, keeping the vehicle at idle wears the life of the oil a bit faster... And just generally get in there and check that you are good on all gaskets, seals, belts, vacuum hoses, check ur plugs and such. Probably not a bad idea to flush ur coolant with new if it's really old.
And generaly keep an eye on oil pressure and your temp gauge so you can catch it if something is gone wrong and shut the engine off...

I used to wake up and turn my engine on for heat then go back to bed for an hour or two every morning without an issue... I used this wifi obd scanner

Paired to my phone so I could see the temps and such without leaving my bed again. Also it's nice to have so you can read and erase codes and have a better idea of what's going on with your vehicle if something is wrong... And on long drives I would use it on data logging mode to catch any issues and adjust my driving to get optimal mpgs.

u/r_golan_trevize · 1 pointr/projectcar

Distributor cap? A 1998 Mustang GT should have a 4.6L Mod motor with distributorless ignition and coilpacks. Bad misfire under load is usually ignition related. Double check everything - sometimes those plug wires don't want to seat snuggly with those long boots. Try to keep the wires from draping on bare metal and touching each other too much too.

Do you have a OBDII scanner? A cheap wifi/bluetooth scanner and a halfway decent OBDII app on your phone will give you access to the Mode $06 data which will show you misfire counts on each cylinder even if it's not throwing a code yet. I use this little guy and OBD Fusion on my phone - if you've got an android phone/tablet you can use a Bluetooth adapter instead which frees up your wifi to google stuff while you're connected.

BTW, the Ford computers are pretty conservative about throwing misfire codes or even flashing the CEL during an active misfire - I've had a really obvious and unmistakable misfire not blink the CEL or set a code in my Mustang (it was a bad wire) while my GMC Sierra will flash and set codes for misfires you can't even feel.

Get an OBD adapter to use with your smartphone. For example, a Veepeak with OBDFusion.

That combo will be far more helpful than any generic scan tool.

To me, it sounds like a vacuum leak. If that's the case, you'll need to do a smoke test. You can take the car to a shop to have a smoke test done, or you can do it yourself with a cheap fluid transfer pump, some rubber glove, and a cigar:

If it's not a vacuum leak, the most likely culprits are o2 sensor, fuel pump, or MAF sensor.

Pro-tip: Check engine lights are usually pretty easily repaired, but can indicate serious malfunctions inside your engine, and can cause all sorts of cascading problems down the line.

Since 1996, the OBD-II Interface has been standardized and is required in every vehicle sold in the US. So if you have a car in America, made after 1996 - you can do the following:

You can get one of these and an app on iOS/Android, and monitor all sorts of sensor information from your engine, as well as check and clear check engine light codes! It's very cool, and is something I use to monitor the health and performance of my engine on a daily basis.

This is great for easy stuff, but if you're getting codes for something serious like a cylinder misfire you'll have to take it to the dealer or put down a few thousand for the Mazda interface computer.

I've got this this. Can I do it with this thing?

u/LemonyFreshizzle · 1 pointr/cars

No problem, if you are quite worried I recommend that you purchase a Bluetooth OBDII scanner. They pair directly to Android phones and show you exactly what your engine is doing at all times through apps like Torque. They are cheap too, around $20. Your call though as I am 99.9% certain the variation is 100% normal. I spoke to a mechanic at work about the vibration and he says that he has a fairly simple test. If the car vibrates while in park or in gear at a red light, it may be the fault of the transmission mounts. If it stops or gets less noticeable when put in neutral, it may be the engine mounts. There are many other possibilities like timing chains being off but as I said before, hard to tell without physically seeing the vehicle. Here's a link to the OBDII tool if interested. Hope you get everything sorted out!

After rewatching the video, meltedsurfwax may be on to something. Sounds almost like loose trim. Didn't see videos before due to being on mobile.

u/ucancallmevicky · 1 pointr/AskReddit

invest in a cheap OBDII scanner like this one and an application like Torque. With the two you can read and then google fault codes when you get a check engine light. With that knowledge going into the shop you can see if your mechanic is giving you an honest diagnosis

(for the record that is not the OBD Scanned I own, just the one that came up first on Amazon I make no recommendation on that make/model)

u/RayBrower · 1 pointr/CherokeeXJ

Also reccomend Torque pro but I bought this adapter.

u/HittingSmoke · 1 pointr/prius

Sounds like overpriced horse shit to me.

This is $10 (compared to $100 for the BlueDriver) and it works with Dr Prius, Hybrid Assistant, Torque, etc.

> What Makes BlueDriver Different

> >More Codes

> >Read all the codes the other scan tools read and the ones they don't.

Huh? Codes the other scan tools don't? The car turns on your check engine light and reports an alphanumeric error code. There are no codes that scan tools don't read that I've ever heard of. Different cars have different sensors exposed. For example, in the Prius you can read tons of information about the HV system through an ODBII port. You don't need an expensive ODBII reader for this. Torque has PID databases for Priuses that will allow you to read all of these "hidden" sensors and apps like Dr. Prius are made specifically to interface with them.

>> Get the Confirmed Fix

>> No more Googling for unreliable fixes that waste your time and money. Using the same Identifix database professional shops use, BlueDriver will match your vehicle's issue to a verified fix from a database of over 30 million solutions.

This is pretty laughably stupid. Mechanics use the internet, too. Calling Google results unreliable wastes of time and money is ridiculous hyperbole.

Pretty much all the benefits of this thing are software features that can be had from any dongle with the right software. It seems like they're comparing this thing to traditional ODBII reading units instead of other BT units with various app pairings.

I keep a dongle from installed for metrics and I keep the above Veepak dongle around for more advanced troubleshooting. I've been making heavy use of it over the last week as I finally suffered my first battery failure. I can't think of any reason I'd spend $100 on that BlueDriver thing.

u/fuckwindows420 · 1 pointr/raspberry_pi

u/jakkarth · 1 pointr/overlanding

How do these compare to something like this and a phone app like Torque?

u/footluvr688 · 1 pointr/abarth

No problem. If for some reason you still can't get a code to come up, here is a link to the reader I use. I use it in combination with the app Torque. It has been able to read codes on all the Abarth/VW/ and Acuras I've used it on.

u/pug_nuts · 1 pointr/mazda

Yes. Any $20 OBD reader.

I bought this one awhile back and it is all I use now. Much more convenient than the corded ones. And whatever app you use will probably give you the code information instead of having to look it up, as well.

u/6_ft_4 · 1 pointr/Cartalk

I got this one and paired it with the torque pro app. Works great. Can't go wrong for under $20 total.

u/LittleRudeDude · 1 pointr/MINI

No problem. I actually bought an Android tablet for the Torque app...assuming you're using an Apple device?

The reason I got the Android device was because with Apple, you can only use Wifi OBD2's. The Bluetooth has too many restrictions for the OBD2 connection to work. But Android works.

For the Bluetooth connection, I'm honestly not sure how many devices you can have connected at once, and I don't want to give you a wrong answer. Sorry.

Here is the sensor I got:

u/RedNorseman · 1 pointr/Cartalk

He's saying some people can be dishonest when they sell vehicles.

Just because there are the only two codes posted in the ad doesn't mean those are the only codes the trucks computer is posting. Without an ODB-II reader you can't verify that, you have to take the sellers word for it. If you own/buy/rent one you can verify for yourself.

It's cheap insurance to bring one with you and verify. You can buy one that hooks up to your phone for about 20$ from amazon and use an application like Torque on your phone to read the information directly to your phone. You can also buy one that doesn't hook up to your phone for about the same price.

Some automotive stores will even let you rent one with a deposit.

u/corporaterebel · 1 pointr/Cartalk

Check Amazon: OBDII scanner. Here is one for $15 that will probably do the job

You need to learn about cars because your actual life and well being depends on it: literally, figuratively, financially and physically. It is the most expensive and dangerous thing that you will own. If you don't think your car is important: try getting by in life without one.

u/growls · 1 pointr/AdviceAnimals

You can buy a code reader really cheap on Amazon. The one I linked, I use all the time, works well.

In my experience though, some codes don't stayed stored forever. So depending on when the light when off, from the time you get it hooked up to a scanner, the code could be gone.

For 14 bucks though, never wonder again!

u/drummwill · 1 pointr/Audi

get a obd unit for a couple bucks, cheap way to quickly determine what's wrong with the car

sometimes it could be just a blown fuse and that might fix it quickly

u/G_Mero · 1 pointr/Showerthoughts

It's already included in most continental cars. (I don't know much outside of continentals)

u/CCLoveMe · 1 pointr/cars

I bought this one that works great. You can also download the free app – torque from googleplay, or if you want to get more data about your car, you can choose to download other app but that may be cost a little money

u/snickerzz · 1 pointr/bloomington

If you have an android phone, these are great. They pair to your phone and give code read out and ability to reset the light if its just a glitch. You have to have an app on your phone, some are free, but one of the best is only is $5.00 (torque pro). I'm not sure about iphone stuff. (edit: its also nice to have an idea what's wrong before going to a repair person.)

u/amd_kenobi · 1 pointr/CherokeeXJ

Try cleaning your throttle body and run a can of Seafoam in a half tank of gas and see if that helps. Also you might get one of these Blue Tooth OBD2 readers that you can use with smartphone apps like Torque. You can check error codes and watch realtime data from many of the sensors on your engine.

you can, or even lower around a quarter if you want. It will take time to work its way into the fuel system, so you're going to want to go through at least 1/8 of a tank, or more. Or try a full tank like this, every highway run leave it in a lower gear to get the cat cooking hot.

You can clear a check engine code with one of those $20 WiFi or Bluetooth OBDII code readers and an app. Not sure if it can clear the other lights but it’s worth a try.

Forscan is a software you install on a laptop/phone, and use an OBD adapter to change settings within the Ford software.

It sounds crazy, but it’s insane how easy it is. You can change literally any setting on the car, as well as add features. I added the digital speedometer, and tire pressure monitor to screen in the middle of the gauges.

Let me know if you need help with it. Forscan is free, and OBD adapters are like $20-30 on Amazon. I would recommend the OHP ELM27 adapter.

A lot of people use a bluetooth version, I just didn't want to have to worry about the BT connection dropping in the middle of a "write" and have it mess something up.

Make sure you request your ForScan software license as soon as you order your device, it takes about a day to get approved.

I got the Anzo's and the LED grill lights from Amazon.

These are the H7 LEDs I used. (You can't reuse stock H11s) They're unbranded versions of the Oracle's that Stage3 sells, but for about half the price.

u/SilverShrimp0 · 1 pointr/nashville

Well, the failed cat code means your oxygen sensors are probably working fine now. Here's what I would try. Get a ~$20 OBD2 code scanner from Amazon, and an ~$8 can of SeaFoam (from Wal-Mart, Kroger, or an auto parts store). Get your gas tank to about 3/4 full. Pour in the sea foam and use the scanner to clear the codes. Drive for awhile and use the scanner to check whether your sensors read as ready. I think you can have up to 2 sensors not ready with a vehicle model year prior to 2001. Once they're ready, if your check engine light is off, you'll be able to take it through inspection and pass.

u/melikeum · 1 pointr/BMW

u/BrownNote · 1 pointr/Jeep

It can be really useful for any lights that come on. If you see yourself fiddling with your own cars in the future and have a bit of disposable income you could get a nice high quality one like this which will do everything you need, or you could get something as simple as this one to take care of most of your needs. Autel is a good brand, I also have a bluetooth one that connects to any app on your phone (or computer) which can also be convenient, and depending on the app can be useful giving you real-time data.

Note that for this issue specifically, you'd need the former one I linked as the airbag system (SRS) and ABS system run on a specialiszed part of the system and can't be read by normal code readers. So if you just figure you won't do much you could get the $15 reader for quick troubleshooting and take it to Autozone like you're doing for when big things come up.

It's an OBDII port. You can plug one of these in to read Diagnostic Trouble Codes.

u/thesandiegan · 1 pointr/AskMechanics

This is probably the most basic of basic scanners, it will allow you to read and clear codes but wont provide any further diagnostics, you can scan the code which will usually start with a P0*** and then you can research the code via internet about the cause and possible solution. Most codes are very vague on very big systems. Also take with a grain of salt that the code found could may say one thing, but be caused by something else seemingly not related to the code. Its a starting point for diagnostics.

I seriously recommend buying your own code reader. Amazon has them for as little as $16 right now. With a little Google research, you are much better armed with information if you need to go to a shop to get your car fixed. Here is an example:

If they quoted you $3200 its probably a professional scan tool, those can read anything going on in the cars computers and even take control of stuff too. If you just want to see what's causing the check engine light and of the above 3 would work.

this last one is more expensive, but it can read obd2, abs, and air bag codes. Pretty much everything the big $3k unit does.

u/GardenGnomeOfEden · 1 pointr/AdviceAnimals

You should get an OBDII diagnostic tool. I bought this one. You plug it in under your dashboard and it gives you a code which you can look up to see what is wrong with your car. It also gives you the option to cancel the check engine light.

u/jrbless · 1 pointr/tasker

A simpler option is to tie things to a bluetooth device that is always in the car, and is only turned on when the car is turned on. There are bluetooth car kits available. Another option (if you don't want a car kit) is to get a bluetooth ELM327 adapter like this It plugs into the ODBII port on the car. If you install an app like Torque you can read the information from your car computer as well - helpful if the "check engine" light comes on.

u/psyki · 1 pointr/BmwTech

Unlikely. The check engine light comes on for a variety of reasons but fuel economy and tire pressure is not one of them, not directly at least. What is causing the check engine light to come on may indirectly affect your fuel economy but it definitely won't come on just because the mileage has gone down or the tire pressure sensor light is on.

Get one of these ($13) and any one of the myriad programs for your phone that will read your codes. Torque is excellent if you have Android, and there is a free version.

u/hellfire1394 · 1 pointr/MechanicAdvice

I don't know how air bubbles get trapped at the bottom of the radiator and I never serviced coolant before. I have this obd2 scanner and it only reads coolant temperature from ECT #1 unless in a freeze-frame report where both #1 and #2 are recorded. Is there an app that can monitor both sensor temperature?

u/Snapchat_trap · 1 pointr/starterpacks

Alright I'll rephrase myself, Most modern cars should not have plastic being sucked into the engine block. That is pretty much the only way plastic is going to get onto that sensor that was installed correctly since it's placed right at the exit of the header, or in the header if the engineers felt the need to use more than one upstream sensor (depends on engine). If that is the case than there most definitely is either a hole in the tubing after the filter (What I said previously), there's a hole in your exhaust (But since exhaust has positive pressure I find it unlikely that plastic would get into any holes) Or your intake filter is installed incorrectly/not installed.

Since you know a lot about cars I'll assume you have an obd2 sensor, but if not you can pick one up on amazon for around 10-20$

An OBD2 will be able to tell you if your mass airflow sensor is malfunctioning because it will be getting readings from that sensor, You should definitely check that before replacing the ECU.

Also on most Duramax engine (I only have experience with the Focus and the Fiesta ST but this is true with most vehicles) the upstream O2 sensor is both easy to get to and easy to test, you won't need to jack up your car, just pop the hood.

For those who do not know, about 95+% of the bluetooth OBDII dongles on the market are based on the ELM327 chip or a clone of it:

ELM sells the chip to a manufacturer for not very cheap who then turns it into a finished product like:

The clones generally work fine almost all of the time, but the updated genuine ELM chip covers more edge cases. You can tell the clones from the real ones pretty easily (the price and construction are a dead giveaway). So if you decide to get a clone, there's no need to waste money - ebay is much better than amazon for this purpose:

OBD2 scanners are cheap these days. I use the one I linked to with an app called Torque. Very handy.

u/thehair · 1 pointr/subaru

i just bought this one off amazon but it's for android only. I'm assuming you're using an iphone though? I honestly don't know that much about app radio units, All i know is the dashcommand app is listed on pioneers website for app radio. I believe for dashcommand on iphone you need a wifi obd 2 dongle (same idea as the one i linked to, only wifi).

u/Monkeybomber · 1 pointr/Jeep

Did you have any sort of headwind? If your coolant gauge was normal than I would doubt it was really an engine issue, and cause you have a manual we can rule out transmission fluid breakdown as well.

If you want to get precise measurements of your coolant temps, you can use a bluetooth obd2 coupled with your cell phone to get real time data.

u/WombatWithFedora · 1 pointr/XTerra

I use this one I bought off Amazon:


Some of the cheaper ones are not compatible with all of the OBD2 protocols, which is probably why the one you got doesn't work with your XTerra, but this one complains to be compatible with all OBD2 vehicles 1996 and newer. I have used it with a 2000 Cavalier, 2002 Mustang, 2005 XTerra, 2007 Camry, 2012 Tacoma, and 2015 Versa successfully so that is most likely true.

u/GabrielsTrumpet · 1 pointr/ChevySonic

you should get a cheap bluetooth ODBII sensor like this one:

Then you can read the codes causing the check engine light yourself and you could post em here and maybe someone can help

u/mynameismurph · 1 pointr/Jeep

Good tip.

OP this is the cheap one I have:

Pair that with torque pro lite and you'll be able to get all the diagnostic data off the bus.

I recommend everyone have one on hand. My 2017 has thrown a few CELs since I bought it. Very useful tool to get started on fixes.

u/Zmodem · 1 pointr/FordDiesels

100% agreed!

I bought the BAFX (Android or Windows mobile device only), Amazon link here, alongside the Torque Pro app. Can't go wrong, and gets me all that I need for diagnostic :)

Very good info, buddy!

u/Dumbquestionsplz · 1 pointr/MechanicAdvice

Option 1: Buy one of These, plug it into your car, and check for stored engine light codes.

When the light comes on again, plug it in, and see what set off the light.

Option 2:Go to autozone and have them do the same as option 1

Option 3: Go to a different mechanic and have them check.

You could have any number of issues. My personal car has a P0138 that randomly comes on when it feels like it and that’s not the gas cap at all.

It's the 4-cylinder. The original parts were Denso, but I'm pretty confident that I got the correct Dorman parts. It's a '99 Camry LE L4. EGR Valve, Modulator, VSV. None of the vacuum hose in the VSV/EGR/Modulator system is clogged. I actually checked the 5 or 6 hoses while I was replacing everything. I also sprayed some Gumout Carb Cleaner into into the intake when I took the EGR off. Cleaned the EGR pipe too.

This is the scanner I'm using. I'm also using the Torque app on my phone. As you can see, it offers some nice monitoring. I glanced at that Vacuum Boost graph while I was driving and I think I remember it sitting at around 15 when I was idling and dropping to 3 or 4 once I got going. I didn't check out the O2 graphs though. I'll log some graphs tomorrow and do some real testing.

Thanks so much for your awesome response. Troubleshooting this has been so frustrating and you've given me something to do.

u/mastiii · 1 pointr/yaris

I got new wheel covers like this for mine. There are a ton of options ranging from $25-45.

An OBDII scanner is kinda useful and you can use it with your phone to display info that the Yaris doesn't. Things like MPG, tachometer, etc.

I don't know if this will be useful but I'll throw it out there: wifi hotspot for your car for $20/month. More info here.

Cleaning your car also spruces it up too. Enjoy your Yaris!

Problem is just its a tight fit but ive used it in my 92 crown Vic, my 09 Pontiac G6, my friends Volkswagen Rabbit and a bunch of others. Just if you get any reader like this be sure not to leave it plugged in while you drive. If it causes problems on the CANBUS you'll watch your car go into full seizure mode.

You could also buy an ob2 just to have and use an App Torque is what I use and it will tell you what's wrong. Sometimes it the gas cap or it could be a sensor. Don't let all those lights freak you out.

Here is a link

You don't have to get that one there is alot of options but its always nice to have one laying around.

u/DuckDuckYoga · 1 pointr/Justrolledintotheshop

Maybe you could use a bluetooth OBDII scanner

u/red359 · 1 pointr/Hyundai

It sounds like the car is putting itself into a limp mode or safety mode due to the computer thinking there is a problem. There may be an actual problem, or perhaps a sensor has failed and is falsely reporting an engine overheating issue or fuel flow issue. (I'm just speculating, there are many possible issues here).

Check the car parts stores and local mechanics in your area, there should be a few that will check the on-board computer for free to see if any issues are getting logged.

You can check it yourself if you get a scanner like this that pairs with a smartphone or tablet.

u/Inconspicuous_User · 1 pointr/CherokeeXJ

My bad, the BAFX is a good, simple, inexpensive OBD dongle and it looks like I spoke prematurely about it dying, lol (key on is important, Doh!)...


I'm still wondering if the increased speeds of the OBDLink MX+ may be worth it though as well as the increased data pids for my Toyota.

u/poke826 · 1 pointr/nissanleaf

I bought the dongle on Amazon (link). I used it with LeadSpy a few times before making my decision. The state of health when up quite a bit when the firmware was updated. I checked it a few times after that and it went up and down very slightly - not enough to matter. I did end up buying out the lease. I'm happy with the decision. I might have splurged on a Model 3 if it was $35K at the time. It would be nice to have a car I could use for road trips but the Leaf is great for commuting.

The OBDII tool is here:

The Android software I bought is called Carista:

Carista works with several OBDII readers but not all, the above one works, I know from personal experience.

The main reason I bought Carista is it allows you to customize a bunch of hidden features on your car, like disabling horn beep when you lock doors, enabling you to open and close windows with key remote, turning on/off daytime running lights & disabling the feature that auto re-locks doors if you unlock the car and don't open any doors within a certain time frame . It just happens to be able to clear that airbag code too.

That, a magnet and sock, a VIN checking website subscription, a friend and a flashlight are the best tools to check on a used car.

Flashlight to inspect crevices.

Friend to start the car from cold while you inspect the color of the exhaust. Then, shift in and out of first and reverse to see if the engine is stable. Then, the friend depresses the clutch, and you listen for chatter. Then a few WoT and you look and listen.

Magnet goes in the sock and you touch it to suspect areas. If it falls, there was rust repair (or it's a plastic panel. Haha).

The reader will scan for any fault codes that currently exist. It will not look for old codes, but it'll tell you if its a O2 sensor or misfire.

A VIN checking website subscription like AutoCheck or CarFax to check if there have ever been accidents or if there's a healthy service record. For that matter, demand all the service records. If they don't have them, don't believe anything they say, and imagine that the vehicle has never had service.

I say all of this as a guy who got fucked each time he bought a used car. My GTI had a hidden accident I could have found with a magnet. My wife's Passat was a lemon (legally. It failed six times under the previous owner), but it wasn't revealed at the time of purchase, and we didn't check the VIN. And more. Three more. Which accounts for five of the five used vehicles I've bought.

u/G-wow · 1 pointr/aww

Response as a whole, for the 'non-believers' the cooling, heating and engine is all linked. If you're engine just started up and you're pulling heat away from it before it can build up enough heat to reach optimal'll take longer to heat. You don't want to over heat your engine either, which yes the cooling system is in place to aid with that but it will only go so far. For example if you're driving around slow, not much wind is hitting it or you're sitting idle for extended periods of time, turn your heat up, open the windows if needed. This way more heat can be removed from the engine since there is no significant airflow from the front end of the car.

That's one source which explains how the systems are 'linked' or related. I've come across many in the past that can confirm, the reason being why I've had to look at this up is, my thermostat recently got stuck open a little, I haven't had time to change it as it's too cold to work in the garage (Chicago). My car warms up fine, significantly faster when I don't turn the heat (blower) on as once I turn it on, high enough, before the engine is at optimal temperature I can actually see the coolant temperature drop (the temp gauge on your instrument panel is actually measuring this) So when the thermostat is stuck (in my case, not fully stuck open but partially) the higher the speeds (more airflow) the lower my cooling temperature drops. I can be at optimal (center) temperature on the local roads, get on the expressway and the coolant temperature will actually drop to the quarter mark if I'm on the expressway long enough, if I turn the heater off while on the expressway it will be higher than the quarter mark. Until I change my thermostat it'll just continue to over cool the engine a little.

Side tip, for anyone diagnosing issues on their car and need a obdii reader, I find the one from amazon, when I bought it was $24, connects to my android device via Bluetooth (sorry, this one is not ios compatible, last I checked) and gives me fault codes if there is a check engine light on and live readings of my car's readings directly from the ECU; coolant temp, rpms, o2 voltages, a/f ratios, etc.

Oh the app is called 'torque.'

While I'm at it, here's the obdii reader from amazon - BAFX Products - Bluetooth OBD2 scan tool - For check engine light & diagnostics - Android ONLY

u/_A_z_i_n_g_ · 1 pointr/Cartalk

Buy this:

When it arrives, dowload Torque Lite, plug in the scanner to your OBD2 port(usually somewhere under the steering wheel, you can look up where exactly it is in your car). Once you plug it in, turn the car on(just on battery is fine), pair the scanner to your phone, and start the app. Then, in the app, load the logged fault codes. Look 'em up and you'll know exactly what's up with your engine. Then go get that stuff fixed

Edit: also, until you do this, drive the car as little as possible, since you don't know what's wrong with the engine.
Hope this helps!

u/fictionthatspulp · 1 pointr/ft86

You can find the ELM327 on ebay for little as 3 Dollars. However, cheaper readers run into issues with J1850 & CAN protocols which can get annoying. I personally use a BAFX Products 34T5 and a cable with switchable power so im not stuck draining battery or needing to remove the reader. The Pixel XL should have no issues in the slightest with torque or DashCommand.

Shameless self promotion.... I recently made a video on both the BAFX reader install (if you wanna call it that lol) and a comparison video between Torque and DashCommand.

u/renterjack · 1 pointr/Volkswagen

u/phantom_eight · 1 pointr/Albany

Sorry for writing you another long book...

I asked my wife if she thought it was loud and she shrugged her shoulders at me... lol. It's slightly louder than my Corolla, but I don't think it's that bad at all. Unfortunately it can be quite subjective. Small cars will always be louder and the manufacturers tend to skimp on sound insulation for the smaller lower priced cars. Also tires can make quite a difference in road noise, but an entire Reddit post/argument can be devoted to that....

As far as gas mileage, we both drive like asses... which means we inherently get worse gas milage than normal people... I did hook up one of these and paired it with an Android App on my phone. It reported that that we were getting 30-34mpg when doing about 80mph on the Thruway. Not sure about averages, but it gets good gas milage. My wife has the 2010 and it's a bit stripped down, not sure if the newer 2014 models display all the fancy info like mpg, range, avg speed and whatnot in the dash...

I've also been thinking about this for a while. If you haven't been exposed to Toyota's you'll find that they are a little simpler than American cars. If you just want to get from point A to point B without a hassle you won't care, but the Ford Fiesta might feel "nicer" inside and have a few more bells and whistles... to each their own. If you decide to look at a Yaris, you might want to test drive one at Lia and then say you'll come back and/or that you are continuing to look at other brands/models as you try to decide what you want. That way you won't be driving far to find out that you perhaps might hate the Yaris. Then if you do decide to check out Prestige... it won't be your first rodeo either.

Also, there is one weird thing about Prestige that I wanted to share with you... the two times I've test driven a car with them the dude always rode with me on the test drive and we always took the same short route around the dealership. I've test drive quite a few cars and they are the only dealer that I've known that didn't toss me the keys and said "have fun see ya when you get back". Then again I'm a talker if you haven't noticed and we are usually shooting the shit the whole time anyway... I also never cared to resist and ask to take the car out alone or to take a different route, they might just say "Sure!" if you ask. The last purchase was my 4th Toyota so I'm familiar with them and really am just looking to abuse the car as much as possible to expose any mechanical BS with brakes, suspension, engine, and transmission. I straight up warned them both times as we left that I was going to:

  1. Floor it at least once.
  2. Force the car to downshift under duress/hard acceleration such as up the hill leading behind and away from the dealership
  3. Throw the car back and forth left to right like a race car during a caution.
  4. Get up to 65ish at the crest of the hill just before the dealership and then get hard in the brakes going down the hill back towards the dealership (dude practically shat himself both times even though I said I was going to get hard in the brakes, but they get it... their cool)

    I will say that the next time I do a test drive with them, I'm going to ask to take it out to RT 299 over to the Thruway exit so I can get it up to 65-70. I had an isolated issue with one of my wheels with my last purchase from them. I didn't notice until I got on the highway and even then it took me a few days of driving to work to notice the issue and then a couple more to decide if I was just crazy or if there was actually something wrong with the wheel. Of course they fixed it for free.

    One other thing... Make sure the car you're looking at has All Season Tires. With my last, I made the mistake of buying a car with good tires... but I didn't pay attention to type of tire on the car. It had practically brand new summer sport tires and only realized it when it drove like shit in the winter. So now I have two sets of tires... but it's ok, I swap them out which extends the life of both sets. The previous owner could have been from another part of the country (cars are bought at auction and shipped around) or perhaps they swapped snow and summer tires and just sold it in the summer...

    Sorry for the book again...

Thanks for the advice!

I didn't know about the Torque app until yesterday. What do you use for your bluetooth adapter? I was considering this one. There's another one that costs about $90 but the reviews for it aren't any better than for this cheaper one. It's basically a serial<->bluetooth converter so shouldn't be too complicated (or expensive). A generic serial<->bluetooth component costs less than $20, so I think that $90 one is probably a rip off.

u/jd101506 · 1 pointr/saab

I have the stock dp for now, and a BSR 2.5in stainless. Car sounds almost stock at idle and under throttle it sounds a little more grunty. Pretty nice.

DICs tend to crack, and the cores in them suffer afterwards. I mean, it's a piece of composite plastic that is sitting on the head of your turbocharged engine... it will get up past 80c on hot days so you gotta expect some damage. It's a great piece of technology as it allows knock control and other engine adjustments RIGHT at the plugs, but it's poorly designed considering where it sits and how it sits there. It's the number 1 thing that can leave you stranded while driving. I've been lucky and have only had one go bad in over 60k of T7 driving (two different t7 cars) but it's a total gamble. Sometimes they will drop within 10k, sometimes within 100k. I've been very lucky considering I only got a CEL from an extra knock sensor. Highly recommend and OBDII reader. Just to pull the code. If you have an android phone ge the torque app and a bluetooth adapter. You can monitor engine health with it and check/clear CELs.

I drive a 00 9-5 LPT that I have converted to be an aero. Turbo, up-pipe, exhaust, brakes, clutch, and a few other mods. Flashed a 00 Aero bin and then the e85 map.

There are a few benefits of the tune. First and foremost being the diagnostics. if you push both the -/+ at the same time on the SID you can access diagnostics. This is activated in T7 Suite and is included in my e85 package. Look here for an example of what kinda data can be displayed:

Things of note:

  • amul = fueling information,
  • tair = intake temps (Important for tuning and IC info),
  • meng = engine torque in nM,
  • teng = engine temp,
  • mair and mreq = mair is air actually delivered, and mreq is the requested air. This is SUPER important to find boost leaks.
  • miss = engine misfires and there's another value for knocks

    Other benefits are the ability to run e85 if you want to. We dont' have any around here, but traveling you may run across one. The increase is hp and torque is an absolute benefit. I find my idle and temps are lower with this tune. Also it evens out the power delivery vastly. Very nice torque curve. You can see the graph here: Top image is stage 1, stock is below. I also find that my throttle response and low end power (Where I usually drive the car) is far better. I'm not a racer, so I tend to stay 2-4k and there's a decent amount of torque there to move me around town.

    Reasons for tuning are my own, but the diagnostics and power increase were the main ones. Having a fun DD helps too.

Get an OASIS report (w/ VIN) from the local Ford dealer to let you know what she has been through (at least while under warranty)

\> there was an exhaust smell when stopped at lights

I have no exhaust or muffler on my 6.0 and don't smell any exhaust when stopped, so that is curious.

I would recommend buying an OBDII scanner from Amazon ($20) if you don't have one (regardless if you follow through with this truck or not it is great to have for all of your other vehicles). They make them with Bluetooth so you can download an app (Torque Pro) for your phone and check/clear codes as well as live data monitoring. It's what a lot of us Ford guys do until we get a tuner that monitors data.

Here is a video that shows what I'm talking about.

That way you can go on another test drive while monitoring the PIDs. Let the truck warm up (180+ F for both oil and coolant) and then hop on the freeway and set the cruise control at 55 mph. Keep it there (on flat ground) for about 15 minutes and monitor the difference between those two temperatures. If they get above 15 degrees apart the truck has a failed oil cooler.

Check the degas bottle and oil for any obvious signs of head gasket issues. Make sure the coolant in that degas bottle is clean (free from particulate) and not milky - likewise with the oil.

Injectors are the other finicky devil with these trucks. When you click the truck onto the on position, keep the door open and listen to the injectors clatter as the spool valves open and close. This is most telling on a bone-cold engine that hasn't been started that day. Those things should clatter fast and evenly. If they start slowly clattering and ramp up their speed as they clatter that could indicate sludge/stiction gauming up the spool valves which leads to contribution issues. Another app called Car Gauge Pro allows you to do a "buzz test" to check for bad injectors by individually buzzing each injector to let you listen. Here is an awesome video that shows how to do that.

I wish I would have known those tips before I bought my baby. Good on you for being far less impulsive than me. With 20 minutes of SUPER easy tests, you can give yourself a really good idea of what kind of shape the truck is in.

Head gasket, oil cooler, and injectors are the big three to keep on your radar with 6.0s. If those are all working properly and the 282k miles doesn't scare you I'd go for it - that's just my 2 cents though.

You better post a picture of that baby if you end up pulling the trigger.

In MPG? Not sure honestly, my gas gauge is inconsistent and I haven't driven it long distance in a few weeks. Though if you believe the gauge, 45 miles (40 highway) cost about a quarter tank, about 8.5 gallons. So that'd be roughly 5MPG but like I said, I don't know how much I trust it given how I only had a quarter tank to start with.

I was going to order this to have a look, would you recommend it, or a different one?

Sort of glad to hear that my goof probably isn't what caused it, and if it's just that emissions thing I won't bother for now since it got inspected in November last year, still plenty of time. But as soon as I'm done typing this I'll hit up AutoZone and see if they'll read my code. Where would I go about finding out what the code means?

Edit: P0137, O2 Sensor. I don't need an inspection sticker until September, so I'm no longer worried. I'll fix it when I get the chance. Thanks for the help!

Since I haven't seen anybody address your data logging question, I highly suggest the Torque app available on android paired with a $25 OBDII reader from amazon. Plus then you don't have to pay $50-$250 on a scanner tool. I've got mine setup to start logging as soon as it connects to my car every time i start it up.

u/mimetic-polyalloy · 1 pointr/androidapps

You should ask what the advantages of that one vs this one are. Mine is a third of the price and posits with my phone, laptop, and tablet running a few different programs.

u/janesmb · 1 pointr/androidapps

Bought 3 before I got one to work on my 02 Grand Prix. GM doesn't work with them all. Of course NONE of the products info tell you this.
Bought the BAFX which worked.

Always check the Kelley Blue Book value.

You may also want to look online for common issues that the vehicle has.

Make sure the check engine light isn't on, and that they haven't disconnected the battery recently (since this is a quick way to clear any trouble codes detected by the car. You should do that with a scan tool, but you can also look for other less definitive clues (like the radio presets being reset).

A scan tool is definitely worth investing in. I personally purchased this bluetooth one, and have some apps on my Android phone to connect to it. If you have an Apple phone, you will have to look elsewhere, or carry a bluetooth capable laptop to check on the sensors.

If you do notice any issues, it's sometimes worth asking the seller if they will be willing to fix it, or if they will be willing to lower the asking price to compensate. If it's something like the battery not charging, the alternator may be bad, but that's something relatively cheap. If the transmission is fucked, you'll be looking at a serious repair bill in the thousands. At that point, however, the seller will probably be interested in finding a sucker elsewhere.

Finally, find out why the seller is selling their car, and how long they've been trying to sell it. If it's been on the market for weeks, that's usually a bad sign - decent cheap college kid cars get snapped up quick.

u/squad_dad · 1 pointr/cars

If I buy one like this, can I leave it plugged in all the time? I have one currently that I have to plug in and unplug every time I want to use it. Not that that's a huge issue - it's right in front of the gas pedal - but if I can find a small form-factor one I wouldn't mind leaving it connected at all times.

u/lncogneato · 1 pointr/northcounty

You can buy a cheap Bluetooth OBDII adapter (which is worth every penny as a diagnostic tool regardless - for about $20 you'll never have to wonder why your check engine light is on again) and use Torque or a similar app on your phone to check your emissions readiness. If your vehicle is a Ford/Lincoln/Mercury I can also very much recommend the ForScan Lite app.

u/boomjay · 1 pointr/BmwTech

I don't think you understood my question - Bank 1 and Bank 2 each have 2 sensors - B1S1 (Bank 1 Sensor 1 - Upstream), B1S2 (Downstream), B2S1 and B2S2.

You need to replace B1SX - What's the X? You should find that out, rather than replacing both (which are about $100 a piece).

If it's a code that's being thrown, you should buy a cheap OBD2 scanner and download Torque (Android) or CarDoctor (iPhone) or another OBD2 app on your phone to read the codes. If you have an iPhone, they usually only support WiFi enabled devices, while Android phones support Bluetooth. I got this ( and it works great, but I have an android.

You can read out what the code is, and it will probably tell you which bank and sensor is throwing it as well (maybe not, but if he narrowed it down to that bank, its worth a shot).

BAFX Products Bluetooth Diagnostic OBDII Reader / Scanner for Android Devices:

u/Metal_Links · 1 pointr/personalfinance

If you have an android phone get a Blutooth OBD 2 reader:
and then download:
to view codes, it will even tell you what the code means, you do not have to get the paid one.

If you don't have an Android just get a handheld scanner.

u/LineBreakBot · 1 pointr/personalfinance

You might have incorrectly formatted line breaks. To create a line break, either put two spaces at the end of the line or put an extra blank line in-between lines. (See Reddit's page on commenting for more information.)

I have attempted to automatically reformat your text with fixed line breaks.

Buy an OBD2 Bluetooth code reader and download the App. Find and research trouble codes for you check engine light. You can often fix issues yourself or ensure you're not overcharged or lied to. Google and youtube is your friend.

u/nycska · 1 pointr/Honda

this one was recommended to me when I got mine, and it has been great.

u/theantnest · 1 pointr/dubai

Best tip for people buying a used car.

Buy one of these:

Put the Torque app on any Android device with bluetooth - iOS devices not supported, because Apple.

Plug the reader into the vehicle's diagnostic port (usually just under the steering wheel), start the Torque app, start the vehicle, then run the Torque test and read faults from the vehicles computer. Take it for a test drive with the app running and the test continuously refreshing.

Will cost you 100AED for the dongle and the app, and from there you can easily run the same test they're going to charge you for at the garage, instantly, on every vehicle you go look at.

Also, as a vehicle owner, the tool is invaluable to have, if and when you have car troubles in the future. Even if you aren't mechanically inclined, you will still know what your vehicles fault is before you even take it to a mechanic.

u/littlfay · 1 pointr/ChevyTrucks

usually those don't work, I bought one just like it thinking hey its cheap, but I ended up buying this one and it has worked flawlessly

u/thisamericanlab801 · 1 pointr/prius

I just purchased one on Amazon last night and it should be here tomorrow. Is there a specific monitor I should get or is any genereic one acceptable?

This is the one that I purchased.

u/TomT12 · 1 pointr/cars

Exactly. I am just a basic DIY mechanic so I didn't really want to spend that kind of money on a scan tool. The torque app is $5 dollars. I bought [this] ( OBDII reader as well. So far it has done everything I have needed. Ill link the app as well, it can really do quite a lot of things.

u/aking14 · 1 pointr/MechanicAdvice

I have this one from Amazon paired with the Torque app on my Nexus 5. Works great.

u/ginjah__ninjah · 1 pointr/f150

this one It's worked pretty good so far for being so cheap.

u/m6877 · 1 pointr/fordfusion

I have used this on my 07 SE 2.3L and my 17 SE 2.5L that gave me all sorts of useful info using ODB Car Doctor Free.

u/wavebro · 1 pointr/WTF

You need this.
Look up Torque on the Play Store.

They are more realiable OBD adapters. Just bought mine last week. So much data.

u/chloroform_vacation · 1 pointr/Android

Oh ok... I found this but I'm not able to purchase it from Europe, sadly. The only other "reputable" option is this, but the LX is $50. You think it's worth it?

All other bluetooth knockoffs have a problem of not even connecting, so I'm not sure if it's worth the trouble.

Thanks for the advice!

u/Tokume · 1 pointr/camaro

I was borrowing the GoPro Hero3+ from my friend who rode with me. I used Torque for my first run, but didn't bother recording the stats on the others since I was just trying to have fun. I use a Bluetooth BAFX ODB II reader with my phone, and it works well.

He also mounts his phone on his windshield an app called SoloStorm to record data from ODB II and external GPS. App also acts as a dash cam which is nice considering that the GoPro was acting up and didn't auto start and record any of his runs unfortunately. In theory it was supposed to trigger the GoPro, but we were having connection issues with it that day, so we started this video manually before the lap.

I didn't edit the video itself except to trim off what wasn't part of the run. Just used iMovie since it was available.

u/shukoroshi · 1 pointr/prius

Lucky you! Now that I've got a branch new hybrid battery, I'm on the hunt for a low mileage Gen 2 Prius. 🤣 At 185k I'm starting to run into more nagging high-mileage issues now.

If you have an Android phone, there's a great app called Dr. Prius that can help you do some diagnostics/health monitoring on the battery. It can help you determine if the battery is on the way out. All you need is a bluetooth OBD adapter and the phone. This is the model I've been using for about 6 years now -

u/thelethalpotato · 1 pointr/Cartalk

You can get one of these from Amazon and connect to an app called Torque on your phone to pull live data.

u/Static_Awesome · 1 pointr/Justrolledintotheshop

Yeah, I know it's a small chance. But sometimes you'll see a description of a problem and go "THAT'S EXACTLY IT!".

Oh? Well -that- I can help out with, for under $30! Setup is mainly bluetooth pairing and turning on the app, worked instantly for me. App decodes codes or looks them up for you, too!
Here's an adapter:

And here's the app to use it ($5):

Itunes (I haven't used this, but have heard the name recommended before):

Alternative iTunes(again, not an apple user, but heard good things):

u/America_Owns · 1 pointr/everymanshouldknow

Early last summer I bought a $1650 car with over 200k miles and have done a lot of work on it because of that...I knew what I was buying. This video taught me that O2 sensors aren't always the easy fix. I found a major vacuum leak that solved my problem. And, with this OBDII reader and the TorquePro App, free version available too, I found out that my O2 sensors are totally fine.

u/Return_Foo_Bar · 1 pointr/CarHacking

I haven't tried yet as the OBD2 Tool arrives sometime today.

Here it is.

u/barnyardman · 0 pointsr/Showerthoughts
u/cosalich · 0 pointsr/funny

A friendly reminder that just about any repair for any vehicle is available on youtube. Give your symptoms a google or post in /r/cartalk. Maybe pick up a cheap OBDII scanner.

I have zero training in person on how to fix cars. Everything I know came from youtube. I now do all of my own repairs. Even if you have to buy tools, the total cost comes out cheaper. When I started doing my own repair work, I didn't know the difference between an intake and a spark plug; if I can do it, you can do it.

u/EC_CO · 0 pointsr/MechanicAdvice

either really expensive and you can read almost anything, or cheaper and you can read most things. not much in between. for under $30 you can do the Torq App and an OBDII bluetooth module and see if this does what you need.

u/xxile · 0 pointsr/verizon

What features of Hum do you value?

Want to read OBDII data on your phone? There's a non-subscription device for that:

Want the Bluetooth speaker? There's loads of non-subscription devices for that.

For me, tracking car data is something that Verizon doesn't need to be involved in.

u/Bjord · 0 pointsr/Hamilton

You could pop one of these guys in your car and see if it spits out any codes that you can lookup yourself

but it's not a full proper diagnostic like a professional would provide, of course. Nifty tool for $20 still.

u/D0esANyoneREadTHese · 0 pointsr/Justrolledintotheshop

Eleven bucks, no real excuse.

u/calcium · -1 pointsr/financialindependence

Here's my suggestion if you want to pass emissions but don't want to repair your car. Go online and get yourself an ODB2 scanner for less than $20. Then when you pull up to the smog place next time, plug it in and clear all the codes on your car and then run the emissions test.

As long as the light doesn't come on during the test, you should be good to go and could pass your test. You can also go somewhere like AutoZone and have them check the code on your car for free to see what it is.

u/jamie79512 · -1 pointsr/whatisthisthing

Possibly a wireless diagnostic tool like this one?

I didn't see you initially mentioned that it won't turn over without it, which isn't the case with these diagnostic tools AFAIK.

u/stiv2k · -2 pointsr/MechanicAdvice

Make sure you get a genuine adapter. I have one from a company called BAFX products. The first one I ordered from newegg turned out to be a counterfeit and it would not work. It didn't mess up my car or anything, it just didn't work. I had to buy another one from Amazon which was a genuine product and it works flawlessly.

EDIT: ok who's the wise guy downvoting me?
