Definition

The OBD2 code P058C indicates a problem with the range or performance of the cruise control or accelerator pedal position sensor 'A', suggesting that the sensor is not functioning correctly or is out of its expected range

Common causes

  • Faulty accelerator pedal position sensor
  • Damaged wiring or connectors in the accelerator pedal circuit
  • Malfunctioning cruise control module
  • Issues with the throttle body or throttle position sensor
  • Vacuum leaks in the intake system
  • Software issues in the engine control module (ECM)
  • Faulty brake pedal position sensor
  • Electrical interference or shorts in the circuit

Common misdiagnoses

  • Throttle position sensor issues
  • Accelerator pedal position sensor failure
  • Cruise control module malfunction
  • Wiring or connector problems
  • Engine control module (ECM) faults
  • Vacuum leaks
  • Faulty brake pedal switch
  • Transmission issues
  • Misadjusted throttle body
  • Software glitches in the vehicle's computer system

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other related trouble codes. Sometimes, multiple codes can provide more context for the issue

  2. 2. Inspect Wiring and Connectors

    Visually inspect the wiring and connectors associated with the accelerator pedal position sensor and cruise control system. Look for signs of damage, corrosion, or loose connections

  3. 3. Test the Accelerator Pedal Position Sensor

  4. 4. Use a multimeter to test the resistance and voltage output of the accelerator pedal position sensor. Compare the readings to the specifications in the vehicle's service manual

  5. 5. Check for smooth operation throughout the entire range of motion

  6. 6. Check the Cruise Control System

  7. 7. Ensure that the cruise control system is functioning properly. Check the cruise control switch and any related components for faults

  8. 8. Verify that the cruise control module is receiving the correct signals from the accelerator pedal position sensor

  9. 9. Inspect the Throttle Body

  10. 10. Check the throttle body for any obstructions or carbon buildup that could affect its operation

  11. 11. Ensure that the throttle position sensor (TPS) is functioning correctly, as it can impact the cruise control system

  12. 12. Look for Vacuum Leaks

    Inspect the intake system for any vacuum leaks that could affect engine performance and the operation of the cruise control system

  13. 13. Check for Software Updates

    Sometimes, manufacturers release software updates for the engine control module (ECM) that can resolve issues related to sensor performance. Check with the dealership for any available updates

  14. 14. Clear the Codes and Test Drive

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

  15. 15. Consult a Professional

    If the issue persists after performing these steps, it may be necessary to consult a professional mechanic or technician who has experience with your specific vehicle make and model. By following these troubleshooting steps, you can identify and potentially resolve the issue related to the P058C code
