po154 is stumping me
I've had trouble with the passenger front o2 sensor since I got the car. I just replaced the o2 sensor because the bosch that was in there was spliced into and I know thats bad. Reset my pcm and I get po154-No activity detected bank 2 sensor 1. Now, I beleive my problem is a broken wire somewhere but I don't know where to look or which wire to follow.
I have a narrow band air/fuel gauge which I can hook up to either sensor via clips that were put on the purple wires off the pcm. When I hook the gauge to the passenger side the readings are very sporatic jumping from deep lean, back to full rich with no in between. It does this even when the car isn't running. So confusing.
Any insight on this code?
