Chrysler Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I will assist you today. Thefre is no O2 sensor heater relay on that model Pacifica. It is either a wiring issue or PCM (ECM). Now the other thing I have seen is after market (Bosch brand) sensors causing this. Use ONLT OEM Mopar O2 sensors. If you still have the codes returning, then inspect wiring. If ok, then replace the PCM.
I hope that my answer/ information was helpful and if so would you kindly take a moment to rate my service using the just answer star rating system? I would really appreciate it. If you need further assistance, I will still be able to help you out even after you rate me. Thank you! Chris
