05 grand prix and bad sensor

[dub shiesty]

So my check engine light came on and the man from autozone said that my 02 sensor is bad. I would think that with the car only being this old that wouldn't be the case. However if that is the case is there a way to determine which one is the faulty one. Gas milage hasnt seem to take a hit as well. Any help is appreciated.

The code will tell you what sensor it is. It is either an issue with the wiring or the sensor, probably just the sensor.

ok, thanks for the reply. Is it common for sensors to go soon.

your car is almost 6 years old. Yeah gm has had a lot of problems with 02 sensors.
