P2116 Throttle/Pedal Position Sensor "E" Minimum Stop Performance

The OBD2 code P2116 indicates that the throttle or pedal position sensor "E" is not functioning correctly, specifically that it is not reaching the minimum stop position as expected, which can affect engine performance...

Definition

The OBD2 code P2116 indicates that the throttle or pedal position sensor "E" is not functioning correctly, specifically that it is not reaching the minimum stop position as expected, which can affect engine performance and throttle response

Common causes

  • Faulty throttle position sensor (TPS)
  • Damaged wiring or connectors
  • Throttle body issues
  • Faulty accelerator pedal position sensor
  • Software or calibration issues
  • Vacuum leaks
  • Malfunctioning engine control module (ECM)

Common misdiagnoses

  • Throttle body issues
  • Accelerator pedal position sensor failure
  • Wiring or connector problems
  • Engine control module (ECM) failure
  • Vacuum leaks
  • Mass air flow sensor issues
  • Fuel delivery problems
  • Ignition system faults

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other trouble codes that may be present. Addressing related codes can help in diagnosing the issue more effectively

  2. 2. Inspect Throttle Body and Pedal Position Sensor

    Visually inspect the throttle body and the pedal position sensor for any signs of damage, dirt, or carbon buildup. Clean the throttle body if necessary

  3. 3. Ensure that the throttle plate moves freely and is not sticking

  4. 4. Check Electrical Connections

    Inspect the wiring and connectors associated with the throttle body and pedal position sensor for any signs of damage, corrosion, or loose connections

  5. 5. Ensure that all connectors are securely attached

  6. 6. Test the Throttle Position Sensor (TPS)

    Use a multimeter to test the throttle position sensor for proper voltage and resistance readings according to the manufacturer's specifications

  7. 7. Check for smooth voltage changes as the throttle is opened and closed

  8. 8. Check the Accelerator Pedal Position Sensor

    Similar to the TPS, test the accelerator pedal position sensor for proper operation and voltage readings

  9. 9. Ensure that the sensor is calibrated correctly

  10. 10. Inspect the Throttle Actuator

    If applicable, check the throttle actuator for proper operation. This may involve testing the actuator's response to commands from the ECM

  11. 11. Check for Vacuum Leaks

    Inspect the intake system for any vacuum leaks that could affect throttle performance. A vacuum leak can cause erratic engine behavior

  12. 12. Perform a Throttle Body Relearn Procedure

    After cleaning or replacing components, perform a throttle body relearn procedure as specified by the vehicle manufacturer. This allows the ECM to recalibrate the throttle position

  13. 13. Check for Software Updates

    Verify if there are any software updates available for the ECM that may address known issues related to throttle control

  14. 14. Test Drive the Vehicle

    After performing the necessary repairs, clear the trouble codes and take the vehicle for a test drive to see if the code returns.1

  15. 15. Consult Repair Manual

    If the issue persists, consult the vehicle's repair manual for specific diagnostic procedures and specifications related to the throttle/pedal position sensors.1

  16. 16. Seek Professional Help

    If you are unable to resolve the issue after following these steps, consider seeking assistance from a qualified mechanic or automotive technician. By following these troubleshooting steps, you can systematically identify and address the underlying cause of the P2116 code
