Was bedeutet der Fehlercode?

The code concerns the adjustment of the position sensor for the turbo guide vanes. It is the learned limit for the open position that is outside what is permitted, and the engine control module (ECM) checks it with the engine running. The code can be a knock-on fault from another turbo fault, in which case that fault is traced first. The cause can also be a damaged turbocharger.

Mögliche Ursachen

Knock-on fault from a fault detected by another trouble code test for the turbo and/or turbo control
Troubleshoot according to another trouble code
Damaged turbocharger

Was Sie tun können

1Deal with other turbo fault codes first, since this code may depend on them.
2Check that the connectors at the position sensor are secure and free from corrosion.
3Have a workshop check the adjustment of the position sensor with diagnostic equipment, as adjustment needs workshop equipment.
4If the adjustment is in order, have a workshop check the turbocharger.
