Was bedeutet der Fehlercode?

The engine control module (ECM) requests a certain position for the turbo's guide vanes through a turbo control valve, and the position sensor measures where the vanes actually are. The code is set when the requested position does not match the measured one. Even though the code is named stuck low, it is the difference between requested and measured position that counts.

Mögliche Ursachen

Clogged hoses to the turbocharger or turbo control valve
Damaged vacuum pressure sensor
Damaged turbocharger

Was Sie tun können

1Check the hoses to the turbocharger and the turbo control valve for kinks, damage and blockages, since clogged hoses can cause this fault
2Check that the hoses are firmly attached and not pinched or loose
3If you have a diagnostic tool: compare the requested and measured guide vane positions in live data while the engine runs
4If the fault remains after the hoses are checked, have a workshop check the vacuum pressure sensor and the turbocharger

Check engine light comes on or behaves abnormally
Text message and warning symbol in the display
