Hey all, I went to drive my car one day and got a CEL for the Upstream O2 Sensor not working at all (was reading 0 Volts and heater not functional), I replaced it still same result, nothing. I don't see anything on the forums, google or anywhere for that matter, and when I talked to the dealership, they were like thats not possible and were scratching their heads, went to put a code scanner on my car, saw what I was seeing and said $300.00 to diagnose the issue, and then any labor and parts afterwards, I told them to not touch it and I will find someone who has knowledge of where these sensor connect to on the harness so I can run a multimeter over the connector in the harness, I am almost positive that the wires went bad because of heat breaking them down, but I have no clue which wires on the ECU pins to test across the sensor side.

Does anyone have any Idea which wires they are? and I would have put this in the correct forum but I am restricted to the new members forum since I have lost access to my old account.
