P0136 - HO2S Sensor Circuit Malfunction (HO2S-12) The downstream HO2S sensor(s) are continuously checked for maximum and minimum voltages. The test fails when the voltages fail to meet the calibrated limits. Pinched, shorted, and corroded wiring and pins.
Crossed sensor wires.
Exhaust leaks.
Contaminated or damaged sensor.



Where do I look for these pinched, shorted corroded wires. I dont want to buy a new sensor unless I know thats what it is. I have a bassani catback. Is there a sensor in there or is it before the cat. Sorry I dont know much about this exhaust\sensor stuff. Any help would be appreciated. Thanks.

 

I think the wiring harness for the rear O2 sensors runs over the top of the tranny then splits for the one rear O2 on the drivers side and one rear O2 on the pasenger side. Look at the exhaust pipe near the rear of the transmission for the rear sensors.

 

Just buy the 02 Eliminators and say the hell with it.



Thanks,
