Hva betyr feilkoden?
The throttle unit (ETM) has detected that the PWM signal from the accelerator pedal sensor lacks signal changes for a period of time. The engine control module (ECM) then stores the code. It can be set together with other fault codes, and the root cause may be among them.
Mulige årsaker
- Power supply to the pedal sensor is missing
- Signal cable short-circuited to voltage
- Signal cable short-circuited to ground
- Open circuit in the signal cable
- Loose connections
- Defective accelerator pedal sensor
Hva du kan gjøre
- 1Read off whether other fault codes for the accelerator pedal signal are stored, such as ECM-9520 or ECM-951F, and troubleshoot those first if so
- 2Check the connector at the accelerator pedal sensor and the engine control module for loose connections and oxidation
- 3Use a multimeter to check that the signal cable from the accelerator pedal sensor has no open circuit and is not short-circuited to ground or voltage
- 4Check that the accelerator pedal sensor receives power from its supply and that the battery is well charged
- 5Erase the fault code and test drive. If it returns, have a workshop check the accelerator pedal sensor, and ask whether upgraded software is available for the car
Symptomer du kan merke4
- The idle is uneven
- The car jerks during engine braking
- Throttle response is very poor
- Top speed is reduced
Hva feilen kan påvirke3
- The throttle closes when braking, and pedal input is ignored while the brake is pressed
- Throttle motor control is switched off, the throttle moves to its mechanical stop position and engine speed is controlled by fuel cut-off
- Uneven idle in this state is due to the reconfiguration and should not be mistaken for a driveability fault that was there before
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
