Need some help with O2 codes please
I am getting the following codes after Header install (LTs, offroad X-pipe).
P0036,P0056 and also P0141,P0161- HO2S HEATER CONTROL CIRCUIT, both banks sensor2 and O2 HEATER SENSOR both BANKs, SENSOR2.
I am thinking that it has to do with the wiring being burnt going to the rear O2 sensors due the wiring being to close to the headers. Going to get it on a lift tommorow to check. I have also heard to check the O2 Sensor fuse which Ill do now.
Anyone have any additional input on these codes? Anything else to look for.
Should I check the plugs also to make sure they are not fouling? It seems like the car is running funky with the codes on. When I clear them it runs much better, but next time I restart they are back on.

Rear o2 codes will always show up after a header install if not removed. The pcm recognises the higher flow cats as defective.
