P2011: Intake Manifold Runner Control Circuit Low (Bank 2)

Quick answer: The Bank 2 intake runner control circuit is reading lower than expected.

Drivers also search this fault as intake manifold runner control circuit low bank 2, IMRC circuit low bank 2, bank 2 runner control low input.

Severity: medium Family: powertrain Related paths: 6
Meaning

What P2011 usually means

P2011 means the Bank 2 runner control circuit is being pulled low or cannot maintain the expected control voltage. The practical causes mirror other low-circuit faults: shorted wiring, an overloaded actuator, corrosion causing voltage drop, or a control-side issue that collapses the signal whenever the PCM tries to move the runner system.

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

  • Inspect for rubbed-through Bank 2 harness sections and contamination at the connector.
  • Measure actuator resistance and compare it to the healthy bank if possible.
  • Verify the circuit issue before assuming the intake manifold is mechanically at fault.
Driving risk

Can you keep driving?

P2011 often leaves the engine driveable, but the Bank 2 runner will usually default to a poor compromise position until the circuit fault is fixed.

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.
Symptoms

Common symptoms

Likely causes

Common causes behind this code

  • Bank 2 control circuit shorted to ground
  • Bank 2 actuator or solenoid internally shorted
  • Voltage drop from corroded or loose terminals
  • Harness damage causing intermittent low signal
  • PCM driver issue once external causes are ruled out

Cause phrases often tied to this code: short to ground bank 2, low control voltage, actuator overload, connector contamination, Bank 2 circuit fault.

Diagnostic order

Suggested workflow

  1. Measure Bank 2 circuit voltage during command events.
  2. Inspect the harness and connector for short-to-ground or heavy voltage-drop conditions.
  3. Test the actuator for low resistance or abnormal current draw.
  4. Repair the low-voltage cause and recheck runner control.
  5. Confirm stable Bank 2 operation on a repeat test drive.
Avoid guesswork

Common mistakes

  • Replacing the manifold when a shorted actuator or harness fault was the real issue.
  • Ignoring connector contamination in hot, oily engine bays.
  • Skipping bank comparison that could isolate the fault quickly.
Repair path

Practical fix guidance

  • Repair the short, voltage-drop source, or failed Bank 2 actuator found in testing.
  • Re-secure and protect the harness after repair.
  • Verify Bank 2 runner control now follows commands without low-circuit recurrence.

FAQ

Quick questions about P2011

Can a shorted actuator set P2011?

Yes. A component that draws too much current can pull the Bank 2 control circuit low.

Why compare to Bank 1?

Because the healthy side often tells you whether voltage, resistance, and command behavior look normal.

Is P2011 a mechanical runner-stuck code?

No. It is primarily an electrical low-circuit code, even though a stuck runner can still coexist.
