Was bedeutet der Fehlercode?

The engine control module (ECM) sends a signal to the turbo control valve that sets the guide vane position, and the position sensor reads back where the vanes are. The code is set when the two positions disagree. The name refers to a stuck high reading, but the code covers any mismatch between requested and measured position.

Mögliche Ursachen

Blocked hoses to the turbocharger and turbo control valve
Faulty vacuum pressure sensor
Faulty turbocharger

Was Sie tun können

1Check the hoses to the turbocharger and turbo control valve, since blocked hoses can give this fault
2Look along the hoses for pinching, kinks and loose connections
3With a diagnostic tool, compare the requested and measured guide vane position in live data with the engine running
4If the fault remains after the hoses are checked, have a workshop check the vacuum pressure sensor and the turbocharger

Symptome, die Sie bemerken können3

Check engine light indicates a fault or behaves abnormally
Text and warning symbol in the display
Driving feels poor or power is lacking

Was der Fehler beeinflussen kann2

Engine power and speed are restricted
Exhaust gas recirculation (EGR) is not controlled
