P2006: Intake Manifold Runner Control Stuck Closed (Bank 1)
Severity: Medium Drive gently and get it diagnosed soon.
What does P2006 mean?
The bank 1 intake runners remain in the closed position when the controller expects them to open. Restricted runner movement can limit airflow as engine demand rises and cause hesitation under acceleration.
Generic OBD-II definition: Intake Manifold Runner Control Stuck Closed (Bank 1). Confirm applicability in your vehicle service information.
Common causes
- Carbon buildup binding the flaps
- Failed actuator or vacuum control
- Loose linkage or inaccurate runner feedback
Symptoms
- Hesitation under load
- Loss of power
- Surging or poor economy
Diagnostic focus
A stuck-closed result is different from the stuck-open condition in P2004. Check where movement stops and whether the actuator receives its command before deciding the manifold is at fault.
Can I keep driving with P2006?
Severity: Medium Drive gently and get it diagnosed soon.
If the check engine light is flashing or the car runs badly, stop driving and have it checked.
Typical fixes
- Inspect linkage and actuator control
- Check for carbon binding using the engine procedure
- Verify actual runner movement before replacing the manifold
