2003 Chevy Cavalier 4 cyl Two Wheel Drive Automatic
I have replaced the O2 sensor twice now. Both times I still get the check engine lite. I know that the O2 works but the odb code says the o2 circuit is inactive.
did a fuse go or something? At my wits end on this one.
again here are the odb codes.
p0134 o2 sensor ckt no activity(bank 1 sensor 1)
p0130 o2 sensor circuit malfunction(bank 1 sensor 1)
p0135 o2 sensor heater circuit malfunction(bank 1 sensor 1)
again this is the second new o2 sensor I have installed. (The o2 sensor nearer to the motor.)
