Hva betyr feilkoden?
The code is titled signal too high, but it concerns the pulse width modulated (PWM) signal from the accelerator pedal sensor to the engine control module. The code is stored when that signal is faulty, most often because the signal wire touches supply voltage. The throttle response can then feel weak.
Mulige årsaker
- Signal wire shorted to supply voltage
- Damaged accelerator pedal position sensor
Hva du kan gjøre
- 1With the ignition off, check the pedal sensor connector for contact resistance and oxidation
- 2With the ignition on and the connector unplugged, use a multimeter on the signal wire; voltage there indicates a short to supply voltage
- 3If you have a diagnostic tool, read the pedal position in live data with the pedal released and pressed, and check that the value changes smoothly
- 4If the wiring is sound and the fault remains, have a workshop replace the accelerator pedal sensor
Symptomer du kan merke2
- Car feels weak or performs poorly
- Warning symbol and text message in the display
Hva feilen kan påvirke1
- The analog accelerator pedal signal is used instead, if it is working correctly
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
