I am having an issue with my O2 sensor on my 05 turbo. I got a check engine light and immediately took it a local shop for diag. They said the alt was bad so I R&R'd it. The light would not go away so I called the dealer (The ones who actually did the Alt R&R) and they said my OS sensor was bad and they forgot to tell me. So I bought a new sensor and replaced myself. I reset the codes by pulling the batt cable and then recharged the batt as well. When I hooked it up bingo everything was good. We drove it for a couple of weeks without a hitch then out of the blue the ck engine light was back on. So I re-read the codes and I am getting the same symptoms. Bad O2 sensor heater control circuit. Code P 0032 So with the engine off and the battery cable disconnected I checked the voltage comparing your readings to my own and I have one difference. I am getting ground readings from two of the four pins on the power side of the loom. I cannot tell which pins due to visual restrictions but it seems to be pins one and four. I do not know what the sensor readings are on the sensor side as I have no schematic to reference. As it stands the O2 sensor issue causes the system to shut down the alternator until I turn of the key and restart the car then it will go a few more minutes and then re light the alt light as well. The ck engine light will not go away under any operating circumstances. Please any help will be appreciated. Sincerely Gary 'Seven Ft' Sauer
