2002 Chevy Cavalier 4 cyl Two Wheel Drive Automatic
I just installed a new o2 sensor "for the 2nd time" the one nearer the motor, now I am getting all type of odbII codes. "And the track off light now comes on where before only the engine light was on"
o2 circuit no activity (bank 1 sensor 1)
o2 circuit malfunction (bank 1 sensor 1)
o2 heater circuit malfunction (bank 1 sensor 1).
my question is how can I fix this?
have the same problem?
