Was bedeutet der Fehlercode?

The engine control module has registered a signal that is too high from the turbocharger control valve circuit, which is most often caused by the signal wire touching supply voltage. The valve controls boost pressure, so the fault can affect engine running and limit output.

Mögliche Ursachen

Short circuit to supply voltage in the signal wire
Damaged turbocharger control valve

Was Sie tun können

1With the ignition off, unplug the turbo control valve connector and check the contacts for looseness and oxidation
2With the ignition on and the connector unplugged, use a multimeter on the signal wire; voltage there indicates a short to supply voltage
3If you have a diagnostic tool, activate the turbo control valve and listen for a click from the valve
4Have a workshop check and replace the turbo control valve if the wiring is sound
