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

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/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/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/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/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/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/NightGod · 22 pointsr/Showerthoughts

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

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/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/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/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/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/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/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/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/teckademics · 12 pointsr/cars

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.

  2. Leatherman multitool
  3. Have a car? OBDII scan tool + Torque app for Android
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/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/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/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/breastblessed · 8 pointsr/Android

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/Go0m · 8 pointsr/FiestaST

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.

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:


USB Audio:

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/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/imprl59 · 7 pointsr/MechanicAdvice

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/femaledog · 6 pointsr/subaru

I have this thing:

It works well with my car and torque, but my car is older than your car.

u/CarmelSack · 6 pointsr/FiestaST

u/GreystarOrg · 6 pointsr/volt

I've used Torque (Lite) with this OBD2 reader:

Works pretty well for what I wanted (reading codes). I've not used it for anything other than that though.

u/[deleted] · 6 pointsr/MechanicAdvice

I had to buy mine on Amazon. BAFX products.

It works with Torque. So far I have used it on a 1997 BMW 328i, a 2010 Ford E350, a 2004 Pontaic GTO and a 2008 Mercury Mountaineer. All while running Torque on a Galaxy S4.

u/CoolMcDouche · 6 pointsr/MechanicAdvice

Best $22 I've ever spent. Paired with the Torque Pro app. BAFX Products 34t5 Bluetooth OBDII Scan Tool for Android Devices

u/gewdgewd · 6 pointsr/ft86

Get an OBDII reader and the Torque app and see which code it is. Then look up the code and it'll tell you what happened.

Or a standalone OBDII reader.

u/Korzag · 6 pointsr/autorepair

Look into getting an OBD2 scanner that will connect to your phone. My preliminary research makes me think you can get your mileage from the computer that way. Plus, these things are incredibly handy to have when ever you get a check engine light.

u/alitanveer · 6 pointsr/Frugal

Don't worry bro. I got your back. I've had this for the last two years and it has saved me tons of money and trips to Autozone (mostly for family cars). Torque is also awesome and shows you all kinds of cool data.

u/paracelsus23 · 5 pointsr/AdviceAnimals

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.

u/eclectro · 5 pointsr/Showerthoughts

All scanners are not the same, some are better than others.

This is probably the best BIFL "value buy" scanner that works with all cars with obdII interface.

And the Torque app works great with it too.

u/KungFuSnorlax · 5 pointsr/starterpacks

Go buy this code reader on Amazon and then buy the torque app. For like $26 you can see exactly what's wrong on your car and clear codes. So much easier than taking it in somewhere.

u/bryanchalker · 5 pointsr/volt

Several out there should work fine, but I got this one:

Just remember you will need to install the custom PIDs (requiring the $5 purchase of the Torque Pro) for the Volt/Bolt, in order to use properly.

u/bogseywogsey · 5 pointsr/leaf
u/wzrds3 · 5 pointsr/scion

Do either you or your wife have access to an Android device with Bluetooth? If so, you could pick up one of these and use this app to get the same (if not better) results. I have not done this, but one of my old coworkers has this setup on his toaster.

As far as installation goes, anything with an OBD interface is really simple to connect. The hard part is finding a place to mount the display.

u/Turboedtwo · 4 pointsr/Audi

Easy. I've got this.

u/ElCangrejo · 4 pointsr/Justrolledintotheshop

I have two of these. Work great. I have only used them in Ford vehicles though.

u/offermychester · 4 pointsr/projectcar

Also buy the torque app. If you're curious about what you're engine is doing this is the best 30 bucks you can spend. Reads codes, clears them automatically, tells you when your engines warmed up, will display and log the output of your obd sensors.

u/toaster_knight · 4 pointsr/CherokeeXJ

BAFX Products 34t5 Bluetooth OBDII Scan Tool for Android Devices

I use this adapter for everything with torque. Has never failed to connect and is really fast when watching live data. I use the paid version of torque.

u/Effimero89 · 4 pointsr/Showerthoughts
u/paperwaller · 4 pointsr/Justrolledintotheshop

My friend has this one and it seems to work well enough actually. I'm going to order one for myself right now. I have a magnetic phone mount that goes in my CD slot that works really well due to the layout in my car. I might use a spare phone to run as extra gauges and a music player. You could get a BlueDriver but those are about $100 though I hear they are really awesome. Though honestly for just $10 it can't hurt to at least try it out.

Edit: For $20 this one looks to be a bit nicer. I'm ordering one for myself right now. Thanks for reminding me. These are really handy tools and just plain fun to play around with.

u/heyawesomepeopl · 4 pointsr/CherokeeXJ

I got this. Works beautifully everytime paired with the Torque Pro app ($5).

u/C-creepy-o · 4 pointsr/Cartalk

This is what I use. I would stay away from the mini blue ones. I hear they have more issues not working on cars. The one above worked on a 99 chevy c1500, a 99 toyota camry, a 2002 protégé 5, a 2012 mazda speed 3, and a 2002 toyota tacoma.

I use torque pro as my app. It reads code plus a whole lot more. There is a version to check out for free as well, however it costs 5 dollars. Torque lite is the name of the free program.

u/sords · 3 pointsr/LifeProTips

More money, but this will give you more flexibility. I learned about these devices from another redditor. With this device, check your own system and turn off your own engine light. I bought it because I plan on buying a used car in a few months and want to plug it into any potential car I am thinking about buying to read the computer

u/AWildAnonHasAppeared · 3 pointsr/cars

This seems to be the best one out there for $25

Everyone is talking about how awesome and essential it is. Mine should be arriving tomorrow too which is awesome. Good luck!

u/RunsWithSporks · 3 pointsr/everymanshouldknow

I got this one for $18 last year. It went up to $24 now. Works well, just plug it into your OBD slot, fire up Torque and pair it with your smart phone (I use a Nexus 7) and that's it. I keep it in my car and since I always have my phone or tablet with me, I can pull readings whenever I need to.

u/Lucky72114 · 3 pointsr/XTerra

I use an OBD2 Bluetooth reader and the Torque app on my phone to check codes for my 2007. I use this scanner, seems to work well
(I had cheaper bluetooth reader before that worked on my 2008 Frontier, but didn't work on my Xterra).

u/g2g079 · 3 pointsr/LifeProTips

I bought this one about 5 years ago. Still working well. You also need an app. I personally bought Torque Pro for $5, but they have a free version as well.

u/randomusename · 3 pointsr/CasualConversation

I've been using this one-
Had mine since 2012, from Amazon. No complaints here, it has worked well for me. But pretty much any one will do. They all use the same chip.

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.

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. Will post link when I find. Btw I know for a fact that there are other apps that work with this scanner. So don't worry if you do not have android.


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/code-sloth · 3 pointsr/cars

Ramps are useless if you want to take the wheels off, so ideally you'd have both ramps and jack/stands. While it should be common sense, it bears saying anyway: Never get under a car that is only supported by jacks. You need to have it secured on jack stands before you can safely get under it. Jacks can and do fall over or tip, and that's how people get crushed.


  • Multimeter

  • Grippy work gloves

  • OBDII scanner to pull error codes and other readings. Such a handy little bugger. I have [this one] because I have an Android phone and tablet.

  • LED work light, plus a smaller flashlight for tighter areas

    Not Really Tools:

  • Shop towels will soak up pretty much everything from paint to oil without falling to pieces. They're really handy.

  • Mechanic soap, because garages are dirty places and washing your hands for ten minutes with weak soap sucks. I like Orange Goo brand.
u/Chizzoink · 3 pointsr/cars

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.

Total cost would be around $50-75 depending on the phone, and then you have an emergency phone, too.

u/TheGuy968 · 3 pointsr/Hyundai

I just ordered one of these and got this app. It tells you quite a bit about the car, speed, coolant temp, you can even run 0-60 times 1/4 miles. Way cheaper than getting an actual gauge.

u/BGTBGT · 3 pointsr/cars

If you have an android you can do this for $28 to any car with an obd2 port.
Buy the bluetooth obd2 reader...

Then download the torque pro app to your phone.

I use the track recorder plugin to see my autocross run speeds and lateral Gs and such.

u/le_suck · 3 pointsr/CrazyIdeas

This is what OBD/OBDII is for. You can buy a bluetooth OBDII adapter for your jailbroken IOS or stock Android device and use a free app to get all the information a mechanic can during a diagnosis.

u/ghatid · 3 pointsr/Cartalk

If you have a smart phone, you can get one of these:

You can use a free app called "Torque" which gets you a lot of good information. There are other cheaper obd2 bluetooth readers, but they have fewer reviews. (I'm sure they're fine). You get more information than a basic cheapo obd2 reader at the same cost.

u/what_democracy · 3 pointsr/Justrolledintotheshop

OBD to bluetooth dongle? Like this?

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.

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/Torisen · 3 pointsr/cars

If you have an Android phone get one of THESE and then THIS app for your phone. $29 and you can read your codes and learn a lot more about what your car's doing.

The sensor probably works with iPhone too, but I've never tried it.

Here is an Amazon link to one, they are about $20 for the unit and the app I use (the full version is worth it) is $4.99. It's a fully customizable app with tons of data readouts. You can learn a lot about your car this way without breaking the bank.

u/Bloodhoof · 3 pointsr/leaf

Congratulations on your new Leaf! For anyone who doesn't have a similar device already, definitely plug in one of these and connect it with the LeafSpy app on your phone before your 7 days is up:

You want to be sure the battery is in good condition before you lose your opportunity to return the car. Good luck and enjoy your new Leaf!

u/Downtempo655 · 3 pointsr/prius

For 3800 if the HV battery was truly replaced I'd totally go for it. Buy an obdII scanner from Amazon and download the torque pro app on your phone. Ask the seller if it's okay if you run an obdII scanner first before doing so. Check fault codes ect and also do a hybrid battery test with the Prius doctor app. If all looks well and it checks all the boxes I see no reason not to buy it.

I had an old Saturn once with similar symptoms and it turned out to be the EGR valve - I removed it and cleaned it with carb cleaner and a toothbrush. In my case I was able to diagnose as I had an OBDII scanner and the Torque app for my phone:

Good luck!

I have one of those bluetooth ones and use Torque Pro on my Android phones. I have had no issues.

ODBII tool (there is a small one, I havent tested it)

Torque Pro

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/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/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/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/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)

BAFX Products - Wireless Bluetooth OBD2 / OBDII Diagnostic Car Scanner & Reader Tool for Android Devices - Read / Clear Your Check Engine Light & So Much More!

Then get the Torque app

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

Spoiler, everything is normal

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/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/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/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/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.

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!).

Also, I personally didn't get my windows tinted, but I think that is something that you should seriously consider doing :)

If u get a bluetooth obd 2 sensor and download an app I can check codes and more. Ill find the stuff and edit this

Here is a sensor might need to find another to fit ur car so just an example

The app I use is torque

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.

u/GSnow · 2 pointsr/AskReddit

The app is for my Android phone, and is called "Torque". It's available in the regular Android market. It communicates with the OBD gizmo via Bluetooth.

There are several gizmos that will work with it, but the one I got was called the BAFX ELM 327, and I bought it on Amazon for 24 bucks.

It's universal to the point that if you have an OBDII port, it will work. All cars/trucks manufactured after 1996 have this port, which is located under the dash, right beneath you steering column. It's the one they plug the testing machine into when you go to get your car inspected for emissions.

u/withoutapaddle · 2 pointsr/tdi

This is the one I'm using:

Only issues I've had with it were not being able to read any codes on a Prius, but I kinda assumed that was a hybrid thing. Seems to work well for my VW.

u/Lowley_Worm · 2 pointsr/leaf

I don't have an iPhone so I got this one:

u/Perryn · 2 pointsr/prius

This is the one I've been using on my Gen3. It works well with every Android app I've used with it, including using Carista to remove the reverse beeping. Now it only beeps one time when I first put it into reverse.

u/stealth210 · 2 pointsr/Cartalk

Here's the one I got:

And here's the application I used called Torque for android. This is me testing it out on my tablet:

It also does other things like I said checking for error codes, resetting check engine light, data logging, graphing, etc.

u/aerosquid · 2 pointsr/dataisbeautiful

I have Torque on my android that outputs a similar map. Torque also lets you capture all kinds of data if you have an OBDII reader or even without one it would give you a map like this with speeds and elevation changes etc. Bluetooth readers have gotten cheap, i picked this one up from Amazon ($23.99 w/Prime) and it works really well-

u/DarmokNJelad-Tanagra · 2 pointsr/4Runner

Woah that is cool. I was trying to get my tranny temp too, and bought one of those OBD readers (this one: Unfortunately it doesn't seem to work for Tranny temp... is there any way I could combine your code info with this thing to make it work?

u/einulfr · 2 pointsr/CherokeeXJ

Pair it up with Torque or DashCommand.

u/trendicoff · 2 pointsr/LifeProTips

I used the free version to check the error code and clear them (it was a false positive and it hasn't come back, but it would have prevented me from passing inspection)
The device I used is this one:

u/smoothcicle · 2 pointsr/nexus6

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).

I use a BAFX adapter, didn't want to pair the first time I used it after updating to M but did on the second try, connected, scanned no problem.

u/commiecat · 2 pointsr/subaru

Here's what I have:

  • OBDII Bluetooth adapter

  • Torque Pro (Torque Lite is the free version)

  • ActiveOBD TQ plug-in (Standalone free version)

    Torque Pro is an Android app that reads the adapter. Pro version has nice features but feel free to test out the free one first.

    ActiveOBD gives some extra Subaru information. Use the standalone app first to see what it does. The plugin I bought is to view the information within Torque.

You may have a failing DI cassette.

First, get one of these:
Plug is in the footwell under the steering wheel.

Pair it with your Android (phone/tablet) running this app to read the engine codes, etc:

A failing DI cassette may not show a code/CEL and exhibit this behavior.

u/eibv · 2 pointsr/raspberry_pi

Maybe 5 years ago. Hardware is negligible now a days. Just check reviews before you buy. I got this one for $18 a few years ago and have never had a problem with it.

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:

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/shark_and_kaya · 2 pointsr/mazda3

I have this it's reliable, cheap, and it works good. It's bit bulky so if you have the correct transmission, you might hit your foot while shifting.

However torque pro app still have log issues and UI is absolute garbage.I wish someone would come up with a better app.

u/Taurik · 2 pointsr/Cartalk

Download Torque on your phone and buy something like this (this is the one I use):

or go to an autoparts store and have them hook up their scan tool and pull the code.

There's really no point in guessing, as it could be anything.

u/vettenyy · 2 pointsr/Trucks

This is the one I bought:

I use it with Torque Pro on Android.

u/nicksvr4 · 2 pointsr/Android

This is the one that was recommended to me. The previous BT and USB ones wouldn't even connect to my Honda Pilot, but this one did without a hitch at all. And those other ones would work sometimes with other cars (Eclipse, Civic, etc)

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/BlackholeZ32 · 2 pointsr/Nissan

This is the one I use. Haven't had any issues with it.

u/MozeeGrad · 2 pointsr/Trucks

I know the boost I was getting because I was using the Torque Android app with this Bluetooth adapter.

The total investment is around $25 for a full scanner with live data. Check it out. It's worth it.

Edit: It will be closer to $29-30 now I guess

u/Trek7553 · 2 pointsr/androidapps

I use this one. It sticks out a little far so I can't leave it plugged in all the time, but it works great. I use Torque Pro for the app.

u/Scgbiker · 2 pointsr/subaru

obd ii bluetooth from amazon- $23. Maybe worth a try to reset on your own and you can read/reset fault codes using Torque Pro app, don't know if it voids warranty. worth reading into.

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/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/weatherjack_ · 2 pointsr/cars

Here check this. Not limited to this one. Check around.

u/nexussloth · 2 pointsr/autorepair

It works with most android scanner apps (I use carista, it's free). it cost me $20 and works great.

EDIT: also, what error code? (eg: p0400)

EDIT x2: Shot a quick question to my buddy who had issues with EGR shit not that long ago. Try replacing the gas cap. He sank about 150 bucks into his car before a new gas cap fixed his issues. It's a cheap place to start.

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.

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

Edit - That's for Android devices, not sure what OS you use, but that's the device you need for something like that.

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/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/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.

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.

I'm looking into getting this one. Well rated, cheap, and it works with the Torque app.

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'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.

This one worked well for me, I bought one of the little blue cheap ones and it caused my ABS compute to go nuts on my toyota and wouldn't work on our ford. This one works fine with both IIRC.

Although I get so much use out (datalogging) of it I might buy one of the nice $70 ones in the future.

u/BrotherAliMazda · 2 pointsr/mazda3

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.

What I used:

u/NotNotMovies · 2 pointsr/350z

This is the exact one I have. Connects to Bluetooth on your phone (only works with Android) and you download whichever app you fancy. I use torque lite to read the codes

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 buy things like this (you can get them cheaper on eBay) which diagnose the fault with your vehicle and tell you what's up. They send the readings to your phone. You want to get the right one for your vehicle. (I don't have one of these yet, but reviews suggest they work pretty well.)

u/chmod777 · 2 pointsr/BMW

invest in an odbii scanner. Like one of these:

u/Sylithis · 2 pointsr/lyftdrivers

Buy a reader like and the torque app on your phone. Figure out the problem by diagnosing yourself and save a lot of money.

u/Polaris2246 · 2 pointsr/subaru Thats the one I bought. Many of the reviews from users say it works great with Subaru. Quite a few of them specifically sited they worked with their 2011 WRX. Thats why I chose that specific adapter.

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.

u/drgncabe · 2 pointsr/MechanicAdvice

I'd get a code scanner. You can get bluetooth ones from Amazon for $30 (I use this one by BAFX) and use them with Torque if you have android (or if you have a laptop with bluetooth, there's a few applications that work).

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/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.

u/metalsippycup · 2 pointsr/AskLosAngeles

What year is the Van? If it has an OBD2 port, you can purchase this OBD2 Bluetooth Scan Tool and get the app called Torque Pro and follow this video to check emission monitors on your van. You can check your monitor readiness and can go in to get it tested when all monitors are ready. Or you can use the scan tool and app to diagnose what is causing the problem. Might be a lazy O2 sensor.

u/frettsurfer38 · 2 pointsr/MINI

Another thing you could do is to pick up a bluetooth OBD II plugin and download Torque on your phone (android only I think). You can check the fault code there and it will give you the exact code and some other great information that would serve you well before you buy the car.

All in all, its about a $35 investment, plus you can use it elsewhere.

u/loualbano · 2 pointsr/cars

I had bad luck with those little blue ones. They're good because they are small, but for some reason mine couldn't talk to a few cars I tried it on. A friend had a similar experience.

That one is a bit more, but it's worked every time I used it and seems to connect to BT quicker.

Now you're making me wonder if BMWs require a special device. The one I have is this one from Amazon. It works via bluetooth through an app called Torque. It might not work on your car, but we can give it a shot. Is it drivable?

u/bobpaul · 1 pointr/tdi

I use a bluetooth ODB2 module and Torque on my phone. Not only does my dash speedometer report as much as 5mph slower than GPS measures, but when Torque reads the speedometer value directly from the CANbus it gets the same value my GPS shows.

The car knows how fast it's going, but the damn dash display fudges the number so I think I'm driving faster than I really am!

u/jag89 · 1 pointr/nissanleaf

yes exactly $130 for 60 months. I'm really hoping the dealership will work with me on this.
this is the OBD2 reader i just bought.

Don't know about best, because I only have one.

BAFX Products - Bluetooth OBD2. $24 shipped from Amazon -

I don't use it for realtime stats, mostly to precheck before getting a smog check.

I dabbled a little bit with the realtime stats, and seems to be working as intended.

u/JamesIncandenza · 1 pointr/Cartalk

Thermostat on an 06 impala isn't hard, but make sure you buy a [funnel] ( to [burp] ( the system, because you get tons of air in it afterward. You can't do it without it, and you'll overheat if you don't do it right.

Also make sure the replacement has the pin hole up top when you put it back in, otherwise you'll get air trapped in it.

You should consider getting a [scanner] ( which will tell you what the codes are. You can usually figure out the fix from there

u/chubbysumo · 1 pointr/Justrolledintotheshop

>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.

u/Tb0ne · 1 pointr/Cartalk

The check engine light does work.

I used One of these to get the fault codes. Still could be a slowly dying sensor though. Anyway to be sure other than just replace it?

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.

What are you trying to do with it?

u/Pronto295 · 1 pointr/MechanicAdvice

It's this one

Unit is 20 bucks, the app I use is 5, it's sort of a halfway point between an old-school handheld reader and a proper diagnostic sweet. Shows me a lot of live data on top of code reading. I'm sure if I had a newer vehicle it would show me more.

u/rmg22893 · 1 pointr/GolfGTI

This is what I have for my general diagnostics (reading CEL codes, etc). Pairs to your phone (Android in my case, don't know if the one I linked works with Apple) and you can pull up all sorts of info on your vehicle.

u/stealer0517 · 1 pointr/UnethicalLifeProTips

I think bluetooth adapters are a bit more than the $5 the person above said. I got mine for $20 and it works great with the high speed mode in torque. I'm sure you can find a china special for $5-10.

u/Quillava · 1 pointr/volt

Can't say much about ios compatibility, but I ended up getting this one - BAFX Products 34t5 Bluetooth OBDII Scan Tool for Android Devices - for my Android phone. 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/da9ve · 1 pointr/saab

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.

u/vhalember · 1 pointr/Dodge

Good advice.

He could go with an app like Torque for Android $5, and buy this from amazon for $24.

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.

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/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/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.

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).

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/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/SlinkyAvenger · 1 pointr/batonrouge

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.

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.

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!

Right, I'm saying that I can do all of this already with the cheap hardware on the market (example).

This is the code reader if in the future you're interested or working on another car. The app was free and I seriously love it. Code readers that a garage use are expensive because you're paying for a powerful handheld computer, but most of us already have powerful handheld computers!

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.

I do the same thing. Torque is awesome!

edit: I use a less expensive adapter without any issues.

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.
u/ZirbMonkey · 1 pointr/MechanicAdvice

I just got This one off Amazon

It cost $'23 instead of $'13, but the reviews are higher because it seems to work on more cars with less problems than the $'13 version the other guy recommended. It comes with laptop software, but also works completely with the Android "Torque Pro" app.

u/Ron-Swanson-Mustache · 1 pointr/AdviceAnimals

I bought this and then this app. Total was $25 for an OBD II scanner that resets some codes as well can display cool and useful realtime gauges to Android devices about all kinds of your car's performance readings.

I see there are other cheaper ones now, but I've used these 2 and know they work great together.

Third or fourth 12V battery, not the hybrid battery, right?

And I'd be looking for something like this? I unfortunately have an old iPhone, so finding an app would be difficult for me, but finding a friend to help out wouldn't be impossible.

u/rocketmonkee · 1 pointr/MINI

I bought this one back in May, and I haven't had any problems with it. I use it with the Torque Pro app, and it's able to pull all kinds of real-time data from the reader. It's not as fancy as some of the more expensive models so it might give you a generic code every now and then, but for the money it's not bad at all.

I don't know if there will be any adverse effects with the manic tune.

That led me to do some google searching. Looks like I could buy this $23 bluetooth adapter and keep track of a lot of information in realtime on my phone with this $5 app. Awesome.

u/dsmaxwell · 1 pointr/Cartalk Buy something similar to this, this is one of the more expensive models, others can be found all over much cheaper. If you have an android or Apple phone then you can connect your car to your phone to get readouts on all kinds of stuff that your car's computer is doing. It seriously is the single most useful diagnostic tool you can have, it might take some trial and error to figure out how to work it if you never have before, but it's pretty straightforward for the most part. It's really all about the app you get. As for a fire risk, it depends on what the problem actually is. If you see smoke, turn it off!

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...

u/N3O9Pr · 1 pointr/MechanicAdvice

Hmmm...any ODB2 reader should connect to the ecu and read the code.

I bought this one in Amazon, but you need an Android. Works great and I can get live data in my 2011 Lancer ES

u/renterjack · 1 pointr/Volkswagen

i bought this thing below (there are others as well). combined with a free android app. you can check codes as well as all sorts of engine info. coolant temp, timing advance, voltage, intake temp, intake flow rate, and alot more. ive found it very handy.

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/_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/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.'

u/D0gDay · 1 pointr/cars


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/sabertooth66 · 1 pointr/jetta

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.

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.

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/Honey_Bunches · 1 pointr/MechanicAdvice

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.

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/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.

I would replace them, it's easy, you can do it in your driveway, you can get the socket you need at an autoparts store for $5. Then you KNOW you're not having a legit issue. My CEL comes on from time to time complaining about o2 slow response or heater issues I use torque on my android and this blue tooth odb2 reader and reset the CEL, if it comes back, then I look into it. I make sure none of the wires on the sensor are broken or have their insulation rubbed off, make sure they haven't come loose and that they are in fact, plugged in :)

Also, when you do replace, use NTK not bosch! The bosch are known to go out early and the NTKs are same as OEM

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:

Bluetooth OBD2 scanners are really cheap now. My fiancé (big car guy who does all of our mechanic stuff) just bought this one. He said usually transmission fluid is brown when it’s old and he’s never heard of it being gray, unless metal is in it. It would be worth the $22 for the scanner to find out what’s going on ¯\_(ツ)_/¯

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.

This is the one I'm looking at. Apparently it isn't AS bad as the 5 dollar chinesium circuits one, but the still aren't in any way a replacement for a proper scanner. I'm also looking at getting two OBDII to ethernet and or USB cables. Might be more functional.

You can buy a Bluetooth OBDII reader for about $21 from Amazon here and it works with the Torque Pro app for $5 on your phone.

Do motorcycles use OBDII ports?

It wouldn't use the Pi but it's cheap and simple solution.

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.

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.

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?
