Was bedeutet der Fehlercode?
The current to the first phase of the throttle motor is outside its normal range, which the engine control module has registered. The second phase then takes over throttle control, and engine output is limited. The fault can lie in the connectors, the motor wiring or the throttle module.
Mögliche Ursachen
- Contact resistance in the connections
- Open or short circuit to ground or supply voltage in the throttle motor signal wires
- Defective throttle module
Was Sie tun können
- 1Check the connectors to the throttle motor and its control unit for contact resistance and oxidation
- 2Have a workshop measure the resistance of the throttle motor and replace the motor if needed
- 3Clear the code and road test to see whether it returns
- 4If nothing is found, the fault may be intermittent or the throttle motor may be defective, which a workshop should check
