P2017 Intake Manifold Runner Position Sensor/Switch Circuit High Bank 1

The OBD2 code P2017 indicates that the intake manifold runner position sensor or switch circuit for bank 1 is reading a high voltage signal, which may suggest a malfunction in the sensor or its circuit

Definition

The OBD2 code P2017 indicates that the intake manifold runner position sensor or switch circuit for bank 1 is reading a high voltage signal, which may suggest a malfunction in the sensor or its circuit

Common causes

  • Faulty intake manifold runner position sensor
  • Wiring issues (shorts, open circuits, or damaged connectors)
  • Faulty intake manifold runner control (IMRC) actuator
  • Vacuum leaks
  • Faulty engine control module (ECM)
  • Carbon buildup in the intake manifold
  • Poor electrical connections

Common misdiagnoses

  • Faulty intake manifold
  • Vacuum leaks
  • Throttle body issues
  • Mass air flow sensor problems
  • Engine control module (ECM) failure
  • Wiring or connector issues
  • Other sensor malfunctions (e.g., camshaft or crankshaft position sensors)

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 all 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 position sensor. Look for signs of damage, corrosion, or loose connections

  3. 3. Ensure that the connectors are securely attached and that there are no broken wires

  4. 4. Test the Intake Manifold Runner Position Sensor

    Use a multimeter to test the resistance and voltage output of the intake manifold runner position sensor. Compare the readings to the specifications provided in the vehicle’s service manual

  5. 5. If the sensor is out of specification, it may need to be replaced

  6. 6. Check the Intake Manifold Runner Control Mechanism

    Inspect the intake manifold runner control (IMRC) mechanism for proper operation. This may involve checking for any obstructions or mechanical failures in the system

  7. 7. Ensure that the runners are moving freely and that there are no blockages

  8. 8. Inspect the Vacuum Lines

    If the intake manifold runner system relies on vacuum, check for any leaks or damaged vacuum lines that could affect the operation of the system

  9. 9. Check for Intake Manifold Leaks

    Inspect the intake manifold for any signs of leaks, which could affect the performance of the intake runner system

  10. 10. Clear the Codes and Test Drive

    After performing the above checks and repairs, clear the trouble codes using the OBD-II scanner

  11. 11. Take the vehicle for a test drive to see if the code returns. Monitor the performance of the engine and the intake manifold runner system

  12. 12. Consult Technical Service Bulletins (TSBs)

    Check for any TSBs related to the P2017 code for your specific vehicle make and model. Manufacturers may have issued updates or fixes for known issues

  13. 13. Professional Diagnosis

    If the issue persists after performing the above steps, consider seeking help from a professional mechanic. They may have specialized tools and knowledge to diagnose the problem more accurately.Conclusion By following these troubleshooting steps, you can systematically identify and resolve the issue related to the P2017 code. Always refer to your vehicle's service manual for specific details and specifications related to your make and model
