Throttle/Pedal Position Sensor/Switch E Circuit

Where it lives

For P2125, the circuit described runs through the sensor. The description of P2125 reports a fault at the sensor.

Check these first

• An open in the throttle or pedal position sensor E circuit
• A short in the sensor E circuit
• Corrosion at the sensor E connector
• A failed throttle or pedal position sensor

What to do next

1. Read throttle or pedal position sensor E on a scan tool
2. Test the sensor E circuit for open and short faults
3. Check the sensor E connector for corrosion
4. Check reference voltage and ground at the sensor
5. Replace the sensor E if the circuit tests good
6. Clear the code and retest
