So I just returned the second defective O2 sensor at autozone, this time I obviously asked for my money back, but I did loose a lot of time going back and forth installing these POS sensors.

Both of them would register 1106 O2s all the time, even with the engine turned off on powrtuner as soon as I connected them....
 


Yeah, we checked that. Actually, I just bought a "TOMCO" one from another store and installed it and it works just fine.
 
fuuuuu now on the way home I got a P0140 no activity from sensor.... the new one is not reporting anything... this is frustrating
 


what is the procedure to test the oxygen sensor wiring? I know I saw a post here about it the other day, but I can't find it again.
 
hop over to gpona and print off the chart for that code and follow the steps and you will figure out the issue.
