Chrysler Repair: Dodge Caravan Fault Codes: translation list, obd ii, dodge caravan

Question
I'm having emissions problems with my Caravan and am looking for a listing of the diagnostic key codes. I see a message for Nov. 30, 2005 in which you interpreted for someone. Are the codes all online somewhere?

Answer
Hi Don,
The codes that can be readout thru about '96 are the obd-I system and they are found at www.allpar.com/fix/codes.html
After that it may or may not be possible to get the codes to readout with the key depending upon the year and model and those are 4 digit codes with the prefix P and are associated with the obd-II system. I can't give you a reference for that list. But let me know what you get and I'll try to give you specific suggestions on how to approach correcting a fault. Tell me the year and engine of van you are working on.
