Hva betyr feilkoden?
The code is titled signal too low, but it concerns the pulse width modulated (PWM) signal from the accelerator pedal sensor to the engine control module. If that signal is faulty, the code is stored. Causes can be poor contact, breaks or shorts in the wiring, low battery voltage, or a damaged sensor.
Mulige årsaker
- Looseness, contact resistance or oxidation in the connections
- Break in the signal wire
- Signal wire shorted to ground
- Break in the power supply or ground wire
- Low battery voltage
- Damaged accelerator pedal position sensor
Hva du kan gjøre
- 1With the ignition off, check the connector at the accelerator pedal sensor for contact resistance and oxidation
- 2Check the battery's charge and condition, since low voltage can cause the fault
- 3If you have a diagnostic tool, follow the pedal position in live data as you press and release the pedal, and check that the value tracks the movement
- 4Erase the fault code and test drive the car; if it returns, have a workshop check the pedal sensor and the wiring
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
