When a Ford vehicle is having issues with the throttle pedal position sensor, the diagnostic code P2128 shows up. This code means that there is a high circuit voltage in the throttle/pedal position sensor/switch E circuit. This can be caused by a circuit short to voltage, or a damaged accelerator pedal position (APP) sensor. To diagnose the problem, readings from the APP2 sensor PID may be taken. Although the code P2128 can be a daunting experience for car owners, there are a few simple solutions to remedy the issue.
Causes and Solutions for Ford Code P2128
| Cause | Solution |
|---|---|
| Circuit short to voltage | Check the wiring and replace any damaged parts |
| Damaged APP sensor | Replace the APP sensor |
| Throttle/Pedal Position Sensor/Switch E Circuit High | Check the readings from the APP2 sensor PID |
| Related Service Bulletins | Check the related service bulletins for further diagnosis |
Circuit Short to Voltage
When the Ford code P2128 is triggered due to a circuit short to voltage, the first step is to check the wiring and replace any damaged parts. This can help to ensure that the wiring is free from corrosion and that the electrical connection is in good condition. Additionally, it is important to make sure that the voltage is within the specified range for the circuit.
Damaged APP Sensor
If the cause of the Ford code P2128 is due to a damaged APP sensor, it is necessary to replace the sensor. This can help to resolve the issue and ensure that the vehicle is running correctly. Additionally, it is important to make sure that the readings from the APP2 sensor PID are within the specified range.
Throttle/Pedal Position Sensor/Switch E Circuit High
When the throttle/pedal position sensor/switch E circuit is high, it is important to check the readings from the APP2 sensor PID. This can help to identify any issues with the sensor and ensure that it is functioning correctly. Additionally, it is important to check the related service bulletins for further diagnosis.
Conclusion
In conclusion, Ford code P2128 is a common diagnostic code that can be caused by a circuit short to voltage, a damaged APP sensor, or a high throttle/pedal position sensor/switch E circuit. To diagnose the issue, it is important to check the wiring, the voltage, the readings from the APP2 sensor PID, and any related service bulletins. By properly diagnosing the issue and taking the necessary steps to repair it, drivers can ensure that their Ford vehicles are running correctly and free from any issues caused by Ford Code P2128.
