12B104 Code
No idea when this code popped up. If it was when I installed my downpipe then it's been there for a veeery long time. Always assumed the CEL was only because of catless but after clearing that with bm3 and it stayed on, I found my problem out. Description reads:
12B104 lambda probe heating before catalytic converter, control cable disruption. I assume my pre cat sensor is damaged? https://www.bootmod3.net/log?id=60b0...729b2a0badd0e7 here are some logs of city driving with I believe one pull. |
