My wife's '99 (4-cyl, auto) camry has the dreaded Check Engine Light. OBD-II codes are P0125/P1135. A web search said try changing the front oxygen sensor.
Haynes said the resistance of the oxygen sensor heater wire should be a few ohms. My sensor says it's an open circuit (wire burned out?)
So I'm pretty sure I really do need a new oxygen sensor.
Now... is it an Oxygen Sensor or an Air Fuel Ratio Sensor?
Dealer wants $222 for it (Air Fuel Ratio Sensor). AutoZone wants about $115 for it (front Oxygen Sensor, Bosch)
I'm in California, and I'll need the California one, of course.
Now I hear that there's a Generic Bosch one, I just have to cut the wires and re-splice. (about $76 at Kragen)
What color goes to which wire? Can anyone post a wiring diagram for me?
Thanks,
Michael
