So I just got this 03 Alero, and after sorting out all the bad mechanic work (various fasteners undone, heater bypass line not bolted and disconnected, spark plugs left un-tightened) I got it started up and running. It had a history of overheating, and I fixed all that. Now I'm throwing the P0327 code. I checked for 5 volts at the sensor wire, and nothing. I traced the wire back to the PCM and tapped off the wire there too, and still nothing
Am I looking at a bad PCM, or would there be something causing no voltage at this circuit? I ran a search on these forums, and found one guy had a bad O2 sensor, but I'm not throwing any other code. Ant help is much appreciated
