Code P2123 MINI Description
The diagnostic trouble code P2123 for MINI indicates an issue with the Throttle/Pedal Position Sensor/Switch 'D' Circuit being too high. This sensor is responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM) to adjust the engine's performance accordingly. When the circuit voltage is detected to be higher than normal, it can lead to incorrect throttle responses and potentially affect the vehicle's drivability.
Common Causes of P2123 MINI
- Faulty throttle position sensor
- Wiring or connector issues
- Corrosion or damage to sensor components
- ECM malfunction
- Mechanical issues affecting the throttle system
Symptoms of P2123 MINI
- Erratic throttle responses
- Reduced engine power
- Poor fuel efficiency
- Stalling or difficulty accelerating
How to Fix P2123 MINI
- Begin by diagnosing the specific cause of the high circuit voltage, using a scan tool to read the code and inspecting the sensor and related components.
- Check the wiring harness and connectors for any signs of damage or corrosion, repairing or replacing them as needed.
- Test the throttle position sensor's functionality and replace it if it is found to be faulty.
- Clear the trouble code from the ECM's memory and perform a test drive to ensure the issue has been resolved.
- If the problem persists, further diagnostics may be required to identify any underlying mechanical issues affecting the throttle system.
Cost to Fix P2123 MINI
The cost of repairing the throttle/pedal position sensor/switch 'D' circuit high code can vary depending on the specific cause of the issue and the labor rates at the auto repair shop. In general, you can expect to pay anywhere from $150 to $400 for parts and labor.
