2013 35xi 02 sensor fuse location
after replacing the DP with a test pipe and reinstalling everything, mhd tuned, i had a CEL.
its not cause the test pipe, its either a faulty sensor or a fuse for the o2 sensor heater from what my research is telling me. that said, having a real hard time finding WHICH fuse it is, in the glovebox or rear cargo. all the diagrams i have seen just dont mark which ones they are. see attached for error code. 12B104 - Oxygen sensor heating before catalytic converter, activation: Line Disconnection. I have double checked the plugs for up and down stream, everything is def connected/seated properly. tia!!!
