02 Sensor Errors
So, I just changed my spark plugs and ignition coils on a 2017 M2 and now I'm getting the following errors:
1B5202- Supply, terminal 15N_1: Short circuit to ground 12B302 - Oxygen sensor heater after catalytic converter 12B102 - Oxygen sensor heater before catalytic converter I'm thinking this is either wiring or an issue with the integrated supply module. Does anyone have a wiring diagram that's actually useful to diagnose this or have any tips on what to try here? |
