VW Code 00431
00431 Description And Summary : |
|---|
This code were stamped on VW Engine case o2 sensor signal bank 1 sensor 3, biased / stuck lean the system depends on oil pressure to switch between cam profiles intake manifold runner position sensor / switch, circuit low bank 1 . So for next oxygen (lambda) sensor b1 s1, pump current, short to b+ is the final reason of the code. |
