How to read CEL codes

[ColoTruckCar]

Hi All, just bought an '05 Turbo 5spd with 180k. Engine has had a lot of work done to it. Stock. CEL just came on. I'm wondering how to get the trouble code from the computer (without going to dealer)? Need an OBD-II reader, right? I've heard of people downloading iPhone apps and buying a cable on eBay that will allow you to diagnose. Is this a good route? Or should I just take it to local auto parts store (O'reilley/Advance/Checker) and see if they'll check it for free? Thanks!

You can get the ODB 2 Blue Tooth adapter from Amazon for 25 and an ap for 5. Or take it to one of the part stores you mentioned for free.

Hey Hocrest, Have you got the bluetooth reader and android app?? I have been trying to find reviews on it but everyone I find they all seem to be mutes... lol.

I got this one, http://www.amazon.com/dp/B005NLCGF8/ref ... 6pb1EKAYQQ from Amazon.

I have a few of the free android aps. Just search for OBD and try them out to find one you like.

I am using the Torque app. on a droid 4 and I really like it. I use a PLX devices Kiwi bluetooth adapter with absolutely no problems. I have tried a few of the $35 generic ebay bluetooth to OBD II adapters and they have all worked flawlessly also.

Ok, good to know! BTW, do the bluetooth / phone integration readers and apps you guys are using offer any functional benefit over just a basic $20 corded handheld like this?:

Those hand held corded ones will work fine for reading and clearing codes. The Bluetooth adapters with the phone apps do have a lot more features and functions. Not only can you read the code but it links you to a web page to look up what the code actually means. You can also pick parameters and datalog them, then email the logs. You can use it as a digital dashboard and select what information you want to view and set it up on the screen as a gauge to view them real time with displayed max/ min values as well. There are several other neat features also. Torque has a track recorder add on that uses the phones camera to record video, then overlays GPS maps and OBD data as well onto the video. it is pretty neat.
