I have a 2003 dodge caravan sport 3.8l with 165k on it. The engine light came on with 2 codes, one for the battery p1684 I believe aswell as one for the o2 sensor heater! I just bought it cert, and etest came back perfect 4 days ago! Could it just be a battery?
I had the guy I bought it from put it on his computer and the engine lights went away, but by the end of the day they were back with the same error codes.
This site is great!
have the same problem?
