check engine, O2 faults.. 96 318i
I have 2 codes being thrown.. P0136 and P1186
oxygen sensor fault. Bank 1 Circuit 2 I reset the fault with my reader, but it came back after a few km.
I have not yet crawled under the car. but I think there are 2 O2 sensors in the 318, pre and post cat.
which one is heated? which one is bank 1 Circuit 2?
also ... anyone have a line as to where to buy a sensor in Canada.. (toronto)
