The throttle pedal position sensor is responsible for communicating the position of the throttle pedal to the ECM, which in turn adjusts the engine's performance accordingly.
Common Causes of P1123 MINI
- Faulty throttle pedal position sensor
- Damaged wiring or connectors in the sensor circuit
- ECM malfunction
- Corrosion or contamination in the sensor circuit
- Mechanical issues with the throttle system
