O2 Heater Poblem, anyone been through this?
I have a 2006 Durango 3.7 With a P0058 Code 2/2 O2 heater High.
I have replaced the O2.
Replaced the PCM with a used unit.
Have continuity on my ground and power, and no shorts.
If i hook up a test light and use the scanner to toggle the heater the light is dim and does not flash i have even tested right at the pcm by opening the harness and cutting the wire a few inches away still same results.
3 used pcm later same issue 8v at %100 duty on the driver, load test ok, continuity and ground ok. Cant find any shorts.
3 pcms with same issue? Not impossible but unlikely.
