Was bedeutet der Fehlercode?

The ECM tracks where the compressor bypass valve sits and compares that actual position with the requested value. The code is stored when the difference between them is too large, while the engine is running and compressor control is active. The result is reduced performance at low engine speeds.

Mögliche Ursachen

Compressor bypass valve is sticking or has jammed
Compressor bypass valve is damaged

Was Sie tun können

1Read and note the code, clear it and road test to see whether it returns
2Look for dirt or sticking at the bypass valve
3Check that the wiring to the valve is intact and that the connector is fully engaged
4If you have diagnostic equipment, read the valve position in live data and compare it with throttle input; the position should follow the throttle smoothly
5If the fault remains, have a workshop check or replace the bypass valve

Symptome, die Sie bemerken können3

The engine hesitates, surges or runs unevenly, especially when slowing down
