P2013 Intake Manifold Runner Control Circuit High Bank 2

The OBD2 code P2013 indicates that there is a high voltage signal detected in the intake manifold runner control circuit for bank 2, which may affect the engine's performance and efficiency

Definition

The OBD2 code P2013 indicates that there is a high voltage signal detected in the intake manifold runner control circuit for bank 2, which may affect the engine's performance and efficiency

Common causes

  • Faulty intake manifold runner control (IMRC) actuator
  • Damaged or frayed wiring in the IMRC circuit
  • Poor electrical connections or corroded connectors
  • Failed IMRC position sensor
  • Vacuum leaks in the intake manifold
  • Faulty engine control module (ECM)
  • Blocked or restricted intake manifold runners

Common misdiagnoses

  • Faulty intake manifold runner control valve
  • Vacuum leaks
  • Throttle body issues
  • Mass air flow sensor problems
  • Wiring or connector issues
  • Engine control module (ECM) faults
  • Fuel delivery problems
  • EGR system malfunctions

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 the Wiring and Connectors

    Visually inspect the wiring and connectors associated with the intake manifold runner control system. Look for

  3. 3. Damaged, frayed, or corroded wires

  4. 4. Loose or disconnected connectors

  5. 5. Signs of moisture or dirt in the connectors

  6. 6. Test the IMRC Actuator

    The IMRC actuator is responsible for controlling the intake manifold runners. Test the actuator for proper operation

  7. 7. Use a multimeter to check the resistance of the actuator

  8. 8. If the actuator is not functioning correctly, it may need to be replaced

  9. 9. Check the Voltage Supply

    Use a multimeter to check the voltage supply to the IMRC actuator

  10. 10. Ensure that the voltage is within the manufacturer's specifications

  11. 11. If the voltage is too high, trace the circuit back to the ECM to identify any issues

  12. 12. Inspect the Intake Manifold

    Check the intake manifold for any obstructions or damage that could affect the operation of the runners

  13. 13. Ensure that the runners are moving freely and are not stuck in one position

  14. 14. Test the ECM

    If all other components check out, the issue may lie with the ECM itself. Testing the ECM can be complex and may require specialized equipment or professional assistance

  15. 15. Clear the Codes and Test Drive

    After performing repairs or replacements, clear the trouble codes using the OBD-II scanner

  16. 16. Take the vehicle for a test drive to see if the code returns

  17. 17. Consult Repair Manual

    Refer to the vehicle's repair manual for specific diagnostic procedures and specifications related to the IMRC system for your make and model

  18. 18. Seek Professional Help

    If you are unable to resolve the issue after performing these steps, consider seeking help from a qualified mechanic or automotive technician. By following these troubleshooting steps, you should be able to identify and resolve the issue related to the P2013 code
