P2114 Throttle/Pedal Position Sensor "C" Minimum Stop Performance

The OBD2 code P2114 indicates that the throttle or pedal position sensor "C" is not reaching its minimum stop position as expected, which can affect engine performance and throttle response

Definition

The OBD2 code P2114 indicates that the throttle or pedal position sensor "C" is not reaching its minimum stop position as expected, which can affect engine performance and throttle response

Common causes

  • Faulty throttle body
  • Malfunctioning throttle position sensor (TPS)
  • Wiring issues or damaged connectors
  • Vacuum leaks
  • Faulty accelerator pedal position sensor
  • Software issues or calibration problems
  • Dirty or carbon-coated throttle body
  • Electrical shorts or open circuits in the throttle control system

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 any related codes can help narrow down the issue

  2. 2. Inspect Throttle Body

    Examine the throttle body for any signs of dirt, carbon buildup, or physical damage. A dirty throttle body can affect the sensor's performance

  3. 3. Check Throttle Position Sensor (TPS)

    Inspect the throttle position sensor and its wiring for any signs of damage, corrosion, or loose connections. Ensure that the sensor is functioning correctly

  4. 4. Inspect Pedal Position Sensor

    Similar to the TPS, check the pedal position sensor for proper operation and any signs of damage or poor connections

  5. 5. Wiring and Connectors

    Inspect all wiring and connectors related to the throttle and pedal position sensors. Look for frayed wires, broken connectors, or poor grounding

  6. 6. Test Voltage and Ground

    Use a multimeter to check the voltage and ground at the throttle and pedal position sensors. Ensure that they are receiving the correct voltage and that the ground connections are solid

  7. 7. Check for Mechanical Issues

    Ensure that there are no mechanical issues preventing the throttle from closing properly. This includes checking for binding or obstruction in the throttle linkage

  8. 8. Reset the ECU

    After performing any repairs or adjustments, clear the trouble codes using the OBD-II scanner and take the vehicle for a test drive to see if the code returns

  9. 9. Inspect the Accelerator Pedal Assembly

    If the issue persists, inspect the accelerator pedal assembly for any faults or misalignment

  10. 10. Check for Software Updates

    In some cases, a software update for the vehicle's ECU may be necessary to resolve the issue. Check with the manufacturer for any available updates. 1

  11. 11. Consult Technical Service Bulletins (TSBs)

    Look for any TSBs related to the P2114 code for your specific vehicle make and model. Manufacturers may have issued guidance on common issues and fixes. 1

  12. 12. Professional Diagnosis

    If the problem persists after performing the above steps, consider seeking help from a professional mechanic or dealership for a more in-depth diagnosis. By following these troubleshooting steps, you can identify and potentially resolve the issue related to the P2114 code
