P2005: Intake Manifold Runner Control Stuck Open (Bank 2)

Quick answer: The PCM sees the Bank 2 intake runner control staying more open than commanded.

Drivers also search this fault as intake manifold runner control stuck open bank 2, IMRC stuck open bank 2, bank 2 intake runner stuck open.

Meaning

What P2005 usually means

P2005 is the Bank 2 version of a stuck-open intake runner fault. It means the module expects Bank 2 runner geometry to change, but the hardware or feedback suggests the runner stays too open instead. That can create a bank-specific idle or torque complaint and can overlap with carbon buildup, vacuum supply issues, or actuator failure.

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

  • Compare Bank 2 runner operation to Bank 1 where applicable.
  • Inspect the linkage and actuator path physically before replacing control electronics.
  • Look for vacuum leaks or cracked hoses if the intake runner system is vacuum-operated.
Driving risk

Can you keep driving?

P2005 is usually manageable short-term, but the engine may feel flat off idle and use more fuel until the runner system is corrected.

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

  • Bank 2 runner plates or linkage binding open
  • Vacuum actuator or solenoid fault
  • Electric runner motor not moving Bank 2 as commanded
  • Position feedback problem on the Bank 2 side
  • Harness or connector issue affecting runner control

Cause phrases often tied to this code: runner flap binding bank 2, vacuum leak IMRC, bank 2 actuator issue, carbon deposits, feedback mismatch.

Diagnostic order

Suggested workflow

  1. Command Bank 2 runner movement and confirm whether the mechanism actually responds.
  2. Inspect for carbon or mechanical interference at the runner shaft and linkage.
  3. Verify vacuum supply or actuator power and ground.
  4. Compare commanded and reported runner position if the PCM exposes that data.
  5. Retest idle stability and low-speed response after repair.
Avoid guesswork

Common mistakes

  • Assuming P2005 is a sensor issue without checking the actual runner hardware.
  • Ignoring bank-to-bank comparison opportunities on V engines.
  • Replacing the whole manifold when only the actuator or linkage fault was proven.
Repair path

Practical fix guidance

  • Repair the specific Bank 2 mechanical, vacuum, or electrical fault found during testing.
  • If deposits are the cause, clean the runner hardware carefully and verify free movement.
  • Confirm that Bank 2 runner behavior follows commands normally before closing the job.

FAQ

Quick questions about P2005

Is P2005 just the Bank 2 version of P2004?

Yes, but the bank-specific hardware and comparison to Bank 1 can speed diagnosis.

Can vacuum problems trigger P2005?

Absolutely, on engines that use vacuum-actuated runner controls.

Will P2005 always cause a noticeable misfire?

Not always. It often causes softer drivability changes like rough idle or weak low-end response instead.
