A few questions for those mechanically minded types on here. Just changed the O2 sensor on our 04' GT wagon, the one behind the turbo, reached from under the hood. Took the car back to the dealer to have the ECU error codes cleared and they tell me the O2 sensor is faulty?? So now they tell me the O2 sensor at the back is faulty and I've changed the wrong one. All my research pointed at the front one. Anyway my questions are;
- how many O2 sensors does the 2004 GT have?
- where are they located (I'm familiar with the one under the hood obviously)
- can they be interchanged - ie - can the front one be moved to the rear. I would be surprised if they were different but who knows.
Thanks in advance for any advice/info etc....
Regards, Matt.
