so my 07 keeps throwing a code for p0155 heater ground issue.
swapped out sensors and from side to side etc. further testing and research shows pin 70 of the pcm should provide ground to bank 2 front sensor. it does not. bank 1 front sensor is getting the ground from the pcm pin 69 like it should, but the pm is not spitting out a ground for the bank 2 sensor, making it throw a code for heater ground.
so my questions is... what does this mean? Is my computer bad?
the car runs like shit unless i turn off the front 02 sensors in the tune.. which i prefer not to do, plus the light stays on regardless
