P058E stands for "Cruise Control System - Input Signal 'A' Invalid

The OBD2 code P058E indicates that the cruise control system has detected an invalid input signal from one of its sensors or switches, specifically labeled as 'A'

Definition

The OBD2 code P058E indicates that the cruise control system has detected an invalid input signal from one of its sensors or switches, specifically labeled as 'A'

Common causes

  • Faulty cruise control switch
  • Damaged wiring or connectors
  • Malfunctioning throttle position sensor
  • Defective brake pedal switch
  • Issues with the engine control module (ECM)
  • Faulty accelerator pedal position sensor
  • Software glitches in the cruise control system

Common misdiagnoses

  • Faulty cruise control switch
  • Malfunctioning throttle position sensor
  • Defective brake pedal switch
  • Wiring issues or shorts in the cruise control circuit
  • Faulty engine control module (ECM)
  • Issues with the accelerator pedal position sensor
  • Problems with the vehicle speed sensor
  • Incorrectly calibrated cruise control system

Troubleshooting steps

  1. 1. Check for Additional Codes

    Use an OBD-II scanner to check for any other trouble codes that may be present. This can provide more context and help identify related issues

  2. 2. Inspect Wiring and Connectors

    Visually inspect the wiring and connectors associated with the cruise control system. Look for any signs of damage, corrosion, or loose connections that could affect the signal

  3. 3. Test the Cruise Control Switch

    Check the cruise control switch for proper operation. Ensure that it is functioning correctly and that there are no stuck buttons or faulty connections

  4. 4. Examine the Brake Pedal Position Sensor

    The brake pedal position sensor is crucial for the cruise control system. Test the sensor to ensure it is working correctly and that it is sending the proper signals when the brake pedal is pressed

  5. 5. Check the Accelerator Pedal Position Sensor

    Similar to the brake pedal sensor, the accelerator pedal position sensor should be tested to ensure it is functioning correctly. Any issues with this sensor can lead to invalid input signals

  6. 6. Inspect the Cruise Control Module

    If the wiring and sensors appear to be in good condition, the cruise control module itself may be faulty. Check for any signs of damage or malfunction

  7. 7. Perform a System Reset

    Sometimes, clearing the code and resetting the system can resolve temporary issues. Use the OBD-II scanner to clear the code and see if it returns

  8. 8. Check for Software Updates

    In some cases, a software update for the vehicle's engine control unit (ECU) may be necessary. Check with the manufacturer or a qualified technician to see if any updates are available

  9. 9. Consult Technical Service Bulletins (TSBs)

    Look for any TSBs related to the cruise control system for your specific vehicle make and model. Manufacturers may have issued guidance on common issues and fixes

  10. 10. Seek Professional Help

    If the issue persists after performing these steps, it may be best to consult a professional mechanic or technician who has experience with cruise control systems and can perform more in-depth diagnostics. By following these troubleshooting steps, you should be able to identify the cause of the P058E code and take appropriate action to resolve the issue
