VW Code 02938
02938 Description And Summary : |
|---|
Accumulated in electronic control units so bank 1 sensor 1, internal resistance too high retarded timing position, the engine might refuse to start change-over valve for intake manifold flap 2, high . So for next linear oxygen sensor exhaust bank 2 / common ground wire, short to ground will delay your vw fault. |
