P2006: Intake Manifold Runner Control Stuck Closed (Bank 1)

Quick answer: The Bank 1 intake runner control appears stuck more closed or restricted than the PCM commanded.

Drivers also search this fault as intake manifold runner control stuck closed bank 1, IMRC stuck closed bank 1, bank 1 intake runner stuck closed.

Severity: medium Family: powertrain Related paths: 9
Meaning

What P2006 usually means

P2006 means the intake runner system on Bank 1 is not opening as it should. A stuck-closed runner arrangement can choke higher-load airflow, reduce power, and distort the engine's expected air-motion strategy. The root cause may be carbon buildup, a failed actuator, broken linkage, vacuum loss, or a feedback circuit that no longer matches reality.

Fast triage

Start here before chasing parts

  • Scan first: save freeze-frame and pending codes before clearing anything.
  • Confirm the complaint: compare the stored code with current drivability symptoms.
  • Use context: trims, live data, and related codes usually narrow the fault faster than guesswork.
  • Work simplest to hardest: leaks, connectors, maintenance items, and known patterns before expensive components.
Initial checks

What to check first

  • Confirm whether the engine feels especially weak as rpm and load climb.
  • Inspect the runner linkage and actuator for a physically jammed closed position.
  • Check vacuum supply or actuator command before replacing intake components wholesale.
Driving risk

Can you keep driving?

P2006 can make the vehicle feel noticeably flat under load. Short trips are usually possible, but the engine will not perform normally until the runner path opens correctly.

Moderate urgency: This code often allows short-term driving, but the right fix usually comes faster when you diagnose it early instead of waiting for more codes.
Likely causes

Common causes behind this code

  • Runner flaps or shaft binding in a closed or restricted position
  • Actuator unable to open the runner path
  • Vacuum control fault or solenoid issue
  • Broken or disconnected linkage
  • Feedback sensor or wiring issue making the PCM think the runner is closed

Cause phrases often tied to this code: runner stuck closed, carbon buildup, failed IMRC actuator, broken linkage, vacuum problem.

Diagnostic order

Suggested workflow

  1. Command runner operation and verify whether the Bank 1 mechanism opens on demand.
  2. Inspect the runner assembly for binding, broken linkage, or deposit-related restriction.
  3. Test the actuator and its control path, including vacuum or power and ground.
  4. Compare sensor feedback with actual movement where possible.
  5. Verify restored power delivery after repair.
Avoid guesswork

Common mistakes

  • Blaming the MAF or throttle body when the real issue is intake geometry staying closed.
  • Ignoring the mechanical side of the runner system and replacing sensors first.
  • Clearing P2006 without confirming the runner can actually open under command.
Repair path

Practical fix guidance

  • Repair the actuator, linkage, vacuum path, or runner assembly that testing proves faulty.
  • Clean deposits only when they are genuinely limiting movement.
  • Confirm that Bank 1 runner position changes through the expected operating range after repair.

FAQ

Quick questions about P2006

Why can P2006 reduce power more at higher load?

Because a stuck-closed runner can become a real airflow restriction once the engine needs more volume.

Can carbon buildup cause P2006 too?

Yes. Deposits can make runner plates or shafts hang up in either direction.

Does P2006 mean I need a whole intake manifold?

Not automatically. Many cases come down to actuator, linkage, vacuum, or deposit problems.
