Was bedeutet der Fehlercode?

The engine control module checks the control signal to the cam profile valves on the intake side, bank 1, and controls the variable cam profiles. The code is set when the control signal is too low, and it is tested with the ignition on. It is a general fault with no more specific description.

Mögliche Ursachen

Dirty or damaged cam profile solenoid
Signal wire shorted to ground

Was Sie tun können

1Read the code, clear it and road test the car to see whether it returns
2Use a multimeter to check that the signal wire to the solenoid is not shorted to ground
3Check the connector at the solenoid for loose or corroded parts
4Have a workshop clean the cam profile solenoid, since metal casting residue in the oil can make it stick
5If you have a diagnostic tool: read the fault status once the diagnosis is complete, where it should show that no fault is found
6If the fault returns: have a workshop replace the cam profile solenoid if it still malfunctions after two cleanings
