Has anyone had to deal with a P0151 fault code on the RS5?
O2 sensor 1 on left bank. (B2)
Did a reset when the CEL first came on then I got 3 related faults the second time…
In addition to the P0151 coming back, I got the following:
P2254- Oxygen sensor B2 S1 negative lead open circuit…
P0150 O2 B2 S1- malfunction in circuit.
All wires seem to be intact and all fuses are good. TBH, I do not have an owners manual so I’m not sure which is the exact fuse to check.
You guys think it’s worth getting an owners manual?
Anyway thank you in advance
