O2 Sensor Heater Issue All 4 Bad at Once?
For my first post in the forums... THANK YOU. I bought this 2012 knowing it had the CEL on and a few issues. Replaced all 4 O2 sensors anyway. Fought with the codes as stated above as well. Just now pulled open the plug to see a minor black smudge on the pin. Cleaned it, dielectric and put it...- rangeboss
