Co oznacza ten kod błędu?
The accelerator pedal has two sensors. The ECM monitors the power supply to sensor 1, and if that supply is faulty the fault code is set. The engine is then controlled by sensor 2 instead.
Możliwe przyczyny
- Power supply wire short-circuited to system voltage
- Power supply wire short-circuited to ground
- Defective accelerator pedal position sensor
- Defective engine control module
Co możesz zrobić
- 1Switch off the ignition and check the accelerator pedal sensor connector for play, contact resistance and oxidation
- 2With a multimeter, check that the supply wire to sensor 1 is not shorted to ground or to system voltage
- 3If you have a diagnostic tool: check in live data that both pedal sensors show reasonable values and track each other as the pedal is pressed
- 4Because the engine is then controlled by only one sensor, have a workshop correct the fault
Objawy, które możesz zauważyć1
- No noticeable symptoms for the driver
Na co może wpływać usterka1
- The engine is controlled by pedal sensor 2 instead
