P0584 Cruise Control System Intermittent

The OBD2 code P0584 indicates an intermittent issue with the cruise control system, suggesting that the system is experiencing sporadic failures or malfunctions

Definition

The OBD2 code P0584 indicates an intermittent issue with the cruise control system, suggesting that the system is experiencing sporadic failures or malfunctions

Common causes

  • Faulty cruise control switch
  • Damaged wiring or connectors
  • Malfunctioning brake pedal switch
  • Faulty throttle position sensor
  • Issues with the engine control module (ECM)
  • Vacuum leaks in the cruise control system
  • Faulty speed sensor
  • Intermittent electrical connections

Common misdiagnoses

  • Faulty cruise control switch
  • Malfunctioning brake light switch
  • Wiring issues or shorts in the cruise control circuit
  • Defective throttle position sensor
  • Issues with the engine control module (ECM)
  • Problems with the vehicle speed sensor
  • Faulty accelerator pedal position sensor
  • Vacuum leaks in the 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. Sometimes, related codes can provide more context for the issue

  2. 2. Inspect the Cruise Control Switch

    Examine the cruise control switch for any signs of wear, damage, or corrosion. Ensure that it is functioning properly and that there are no stuck buttons

  3. 3. Examine Wiring and Connectors

    Inspect the wiring and connectors associated with the cruise control system. Look for frayed wires, loose connections, or corrosion that could cause intermittent issues

  4. 4. Test the Brake Pedal Switch

    The cruise control system is often disabled when the brake pedal is pressed. Check the brake pedal switch to ensure it is functioning correctly and not intermittently cutting off the cruise control

  5. 5. Check the Throttle Position Sensor (TPS)

    The TPS provides information about the position of the throttle to the engine control module (ECM). If it is malfunctioning, it can affect the cruise control system. Test the TPS for proper operation

  6. 6. Inspect the Vehicle Speed Sensor (VSS)

    The cruise control system relies on the VSS to maintain speed. If the VSS is faulty or sending erratic signals, it can cause the cruise control to behave intermittently

  7. 7. Look for Vacuum Leaks

    If your vehicle uses a vacuum-operated cruise control system, check for any vacuum leaks in the hoses or connections that could affect performance

  8. 8. Check the Fuse

    Inspect the fuse related to the cruise control system. A blown fuse can cause the system to malfunction

  9. 9. Test the Cruise Control Module

    If all other components check out, the cruise control module itself may be faulty. Testing or replacing the module may be necessary

  10. 10. Perform a System Reset

    Sometimes, clearing the code and resetting the system can resolve intermittent issues. After repairs, clear the codes and take the vehicle for a test drive to see if the problem persists. 1

  11. 11. Consult the Service Manual

    Refer to the vehicle's service manual for specific troubleshooting procedures and specifications related to the cruise control system. 1

  12. 12. Seek Professional Help

    If you are unable to diagnose or fix the issue, consider taking the vehicle to a qualified mechanic or dealership for further diagnosis. By following these steps, you should be able to identify the cause of the P0584 code and take appropriate action to resolve the issue
