OBDII Chrysler Code Definitions.

Be sure to double check the codes. Anything P1000 to P1999 or P3000 to P3400 will be Manufacturer specific and may not match the ones listed here. Check specific manufacturer pages on the site, as some of them, we list the OBD2 codes on those pages for those specific vehicles.
