P2015
Intake Manifold Runner Position Sensor/Switch Circuit Range/Performance Bank 1
Intake air / manifold runner
Generic OBD-II
High
What it means
P2015 means the sensor that reports the position of the intake manifold runner (swirl/tumble) flaps on bank 1 is giving an implausible reading. These flaps tune intake airflow for low-speed torque and emissions. A common cause is a worn or broken runner-control actuator or linkage, though a faulty position sensor or its wiring can also set the code.

Can I keep driving? Usually drivable, but you may notice weak low-end power or rough running; have it checked before it worsens.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced low-end power or poor throttle response
- Rough running or hesitation
Common causes
Most likely first
- Broken or worn intake manifold runner control (IMRC) actuator or linkage — common on some enginesLikely
- Faulty runner position sensor or switchCommon
- Wiring or connector fault, including the signal shorted to powerCommon
- Blocked or leaking vacuum hoses (on vacuum-actuated systems)Less often
- Faulty PCM (rare)Less often
How to diagnose & fix
Work through it in order
- Scan for related codes and watch the runner position reading while the actuator cycles.
- Inspect the IMRC actuator and its linkage for a broken or stuck lever.
- Check the position sensor's wiring and connector for damage or a short to power.
- On vacuum-operated systems, verify the vacuum hoses and solenoid.
- Replace the actuator or position sensor as diagnosis indicates, PCM last. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2015?+
Generally yes for short trips, though you may feel reduced power. Get it checked so the intake runners stay working correctly.
Can I just clear P2015?+
It will return once the ECM re-tests the runner position, so the actuator, sensor, or wiring fault must be repaired first.
