Co oznacza ten kod błędu?
The code is set when the pulse width modulated (PWM) signal from the accelerator pedal sensor has too low a frequency. The engine control module (ECM) compares the PWM signal with the analogue signal, and the two should follow each other as the pedal moves. The fault may lie in the signal wire, the supply or the sensor itself.
Możliwe przyczyny
- Open circuit in the signal cable
- Signal cable short-circuited to ground
- Signal cable short-circuited to supply voltage
- Power supply cable short-circuited to ground
- Power supply cable short-circuited to supply voltage
- Damaged accelerator pedal position sensor
Co możesz zrobić
- 1Check that the fuses are intact; their locations are in the owner's manual or on the fuse box cover
- 2Make a test drive and note whether hesitation, surging or jerky running occurs, and whether it happens right now
- 3Start the engine and read the pedal movement in live data while pressing the pedal slowly and releasing it; the values should change with the movement
- 4Use a multimeter to check that the supply to the pedal sensor has no open circuit and is not short-circuited to ground or supply voltage
- 5Check the connectors at the pedal sensor and the engine control module for contact resistance and oxidation
- 6Replace the pedal sensor first only if the fault remains and nothing else is found during these checks
Objawy, które możesz zauważyć3
- Yellow warning symbol and a message in the display
- The car lacks power
- The engine hesitates, surges or runs jerkily
