Question about 2000 Dodge Durango
Replaced both o2 sensors, IAC valve and motor, TPS sensors all withing last 60 days. Had code p0171 , but now the light is back on. I found the upstream O2 sensor had came unplugged, now it is back in and I reset the computer. If the light comes back on with same code, what might be the cause?
If the CEL comes back on you probably have a vacuum leak somewhere that is causing the system to run lean. Please let me know if you have any other questions. Thanks for using FixYa!
