5 modeliC30 (2007–2013), C30 Electric (2011–2013), C70 (2006–2013), S40 (2004–2013), V50 (2004–2013)
Co oznacza ten kod błędu?
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.
Możliwe przyczyny
- The signal cable is shorted to ground
- A damaged accelerator pedal sensor
Co możesz zrobić
- 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
