Here’s a list of SOME of them: [http://www.obd-codes.com/trouble\_codes/](http://www.obd-codes.com/trouble_codes/)

Take it to a chain-type auto parts store. Most will scan it and read the codes for free. Write down the exact code (as in “P1234”) and you can post it here.

The possible causes is a list 634 pages long. And that is just the most popular ‘P’ codes, not all of them.

The cause is a simple as hooking up a scan tool and retrieving the code. Many auto parts stores will do this for free.
