Need help with 02 sensor problem...
got an SES light, code reads as follows:
P2C3D Lambda probe before catalyst, line fault. Doesn't give me any indication as to which one needs to be replaced-bank 1 or 2? I'm assuming bank 1 would be for cyl. 1-3, bank 2 4-6. Anyone know for sure which bank this code refers to? Or should I just replace both, although I don't want to spend the extra $150 unless I really have to... '07 335, Cobb Stg.1 93, mileage is 47K. |
