Code P2123 2010 Ford Fusion Description
The P2123 diagnostic trouble code (DTC) for a 2010 Ford Fusion indicates a problem with the Throttle/Pedal Position Sensor/Switch 'D' Circuit being too high. This sensor is crucial for the proper functioning of the vehicle's electronic throttle control system. The throttle position sensor (TPS) is responsible for monitoring the position of the throttle pedal and sending this information to the engine control module (ECM). The ECM uses this data to determine the appropriate amount of air and fuel to deliver to the engine for optimal performance.
Common Causes of P2123 2010 Ford Fusion
- Faulty throttle position sensor
- Damaged wiring or connectors
- Corrosion in the sensor circuit
- Issues with the ECM
- Electronic interference or shorts in the system
Symptoms of P2123 2010 Ford Fusion
- Rough idling or stalling
- Lack of power or poor acceleration
- Check Engine Light illuminated
- Limp mode activation
- Reduced fuel efficiency
How to Fix P2123 2010 Ford Fusion
- Begin by diagnosing the specific cause of the high voltage reading using a scan tool to pinpoint the issue.
- Inspect the throttle position sensor and its wiring for any signs of damage or corrosion.
- Test the sensor's voltage output and resistance to determine if it is functioning within specifications.
- Replace the throttle position sensor if it is found to be faulty, ensuring proper installation and calibration.
- Clear the DTC and test drive the vehicle to confirm that the issue has been resolved.
Cost to Fix P2123 2010 Ford Fusion
The typical repair costs for addressing a Throttle/Pedal Position Sensor/Switch 'D' Circuit High issue can range from $150 to $300, including parts and labor.
