Was bedeutet der Fehlercode?

This variant applies to the C30, C30 Electric, C70, S40 and V50. The CEM checks the voltage on the signal wire from the accelerator pedal sensor. If the signal is too low, the code is set. The engine may feel sluggish and the accelerator pedal may not respond.

Mögliche Ursachen

The signal cable is shorted to ground
A damaged accelerator pedal sensor

Was Sie tun können

1With a diagnostic tool, follow the accelerator pedal sensor signal in live data while you slowly press and release the pedal. The value should change evenly
2Check that the connector at the accelerator pedal sensor is seated and not corroded or chafed
3Use a multimeter to check that the signal wire from the sensor is not shorted to ground
4If the wire is intact and the fault remains, replace the accelerator pedal sensor with an identical one
5After the work, clear the code and road-test the car
