Throttle/Pedal Position Sensor/Switch E/F Voltage Correlation

Where it lives

For P2140, start at the sensor the description names.

Check these first

• A mismatch between the throttle position sensor E and F signals
• A dirty or faulty throttle position sensor
• Wiring damage or corrosion in the sensor E or F circuit
• A failed throttle body or pedal assembly
• An ECM calibration fault

What to do next

1. Read the sensor E and F voltages on a scan tool
2. Compare the E and F signals through the full pedal travel
3. Test the E and F circuits for an open or a short
4. Clean the throttle body and check for air leaks
5. Replace the throttle or pedal position sensor if the signals do not track
6. Clear the code and retest
