P2005
Intake Manifold Runner Control Stuck Open Bank 2
Fuel & air metering
Generic OBD-II
Low
What it means
P2005 means the intake manifold runner control on bank 2 is stuck in the open position. These runner flaps optimize airflow at different engine speeds, so when one sticks open you may lose a little low-rpm torque and the engine won't pass emissions monitoring. The engine still starts and drives normally — the usual cause is carbon binding or a failed actuator.
Low
Can I keep driving? Safe to keep driving — you may notice slightly weaker low-speed pull, but the engine starts and runs normally; fix it to pass emissions.
Common symptoms
What you'll notice
- Check-engine light on
- Slightly reduced low-rpm power or hesitation
- Possible rough or uneven idle
Common causes
Most likely first
- Intake manifold runner control (IMRC) flaps or linkage stuck open (carbon/binding)Likely
- Failed IMRC actuator or solenoidCommon
- Broken or leaking vacuum hose to the runner actuatorCommon
- Damaged wiring or connector in the IMRC circuitLess often
- Faulty powertrain control module (PCM) — rareLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data to confirm the fault is on bank 2.
- Inspect the runner control flaps and linkage for carbon buildup or sticking; clean or free them.
- Check the vacuum supply and solenoid to the runner actuator.
- Inspect the IMRC wiring and connector for damage or corrosion.
- Replace the actuator or solenoid if it doesn't move to command, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2005?+
Yes — drivability effects are minor. The main issues are failing emissions and a small loss of low-end response.
Can I just clear P2005?+
It returns until the stuck runner or its actuator is repaired.
