OBD2 Diagnostic Trouble Codes

Ever wonder how many Diagnostic Trouble Codes or OBD2 Codes can be set by your engine computer (ECM/PCM)?   Well, below is a list of all the Generic (not manufacture specific) OBD2 Engine Diagnostic Trouble Codes.  Once you have plugged into your vehicle’s on board computer, you can go to alldataDIY for step by step instructions on how to diagnose each OBD2 code that may be stored in the computer.  You can also check for Technical Service Bulletins and Recalls released by the manufacturer.  In addition, you can click here to talk to a mechanic and to get some help on how to diagnose and fix the OBD2 code or codes you may have stored in your engine computer.
Here is a free OBD-2 Automotive Code Encyclopedia and Cross-Reference Guide from amazon.com (Kindle Edition).

Here is a free Automotive Code-to-Flowchart Repair Guide (Ford only, Kindle Edition).

Here is a site I also recommend to get the diagnostic trouble code/circuit description.  (Not manufacturer specific)
