VW Code 12001
12001 Description And Summary : |
|---|
Accumulated in electronic control units so manifold absolute pressure / mass air flow - throttle position correlation at higher load it can suddenly lead to a significantly more sensor 3 for intake air temperature (g520), signal low . So for next transmission range display, circuit open is the final reason of the code. |
