P2006
Intake Manifold Runner Control Stuck Closed Bank 1
Fuel & air metering
Generic OBD-II
Medium
What it means
P2006 means the intake manifold runner flaps on bank 1 are stuck closed. These flaps change intake airflow to optimize power across the rev range, so when they stick you typically get reduced power or sluggish response in part of the range rather than a no-start. The engine still runs and starts normally.
Medium
Can I keep driving? Drivable, but expect reduced power or sluggish response in part of the rev range; not urgent, though it should be fixed.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced power or sluggish acceleration
- Rough idle or hesitation
- Slight drop in fuel economy
Common causes
Most likely first
- Intake manifold runner flaps or linkage seized in the closed positionLikely
- Faulty intake manifold runner control (IMRC) actuator or solenoidCommon
- Carbon buildup jamming the runner flapsCommon
- Damaged or disconnected vacuum hose to the actuatorLess often
- Wiring or connector fault, or a faulty PCM (rare)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the IMRC wiring, connector, and vacuum lines.
- Actuate the runner control (by hand or scan tool) to confirm the flaps move freely.
- Clean carbon from the runner flaps and linkage if they are sticking.
- Replace the IMRC actuator or solenoid if it does not move the flaps.
- Clear the code and re-test; the PCM is only a last resort after wiring is verified.
FAQ
Quick answers
Is it safe to drive with P2006?+
Yes — it mainly affects power in part of the rev range and won't leave you stranded, but fix it to restore full performance and economy.
Can I just clear P2006?+
It returns until the stuck runner or its actuator is repaired; clearing alone won't free the flaps.
