P2015 – Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance

Indicates a problem with the position sensing of the intake manifold runner or flap system.

Plain-English Explanation

Many engines use intake manifold runners or flaps to change airflow paths for better torque or efficiency. A position sensor reports flap or runner position back to the ECU. If the sensor signal is out of the expected range, or the mechanism sticks and cannot reach commanded positions, P2015 is stored.

Common Symptoms

  • Check engine light on.
  • Possible loss of low-down torque or responsiveness.
  • On some cars, hesitations or flat spots at certain RPM.

Typical Causes

  • Sticking intake manifold flaps due to carbon or mechanical wear.
  • Broken linkage or stop bracket in the manifold mechanism.
  • Faulty position sensor or wiring.

What To Check First

  1. Perform a visual inspection of the intake manifold actuator and linkages where accessible.
  2. Use a scan tool to run actuator tests if supported and watch position feedback.
  3. Check for technical service bulletins (TSBs) or common fixes for your specific engine.
  4. If the mechanism is known to wear, replacement of the affected parts may be required.
