Generic gasoline powertrain DTC / Intake manifold runner control

P2006: Intake manifold runner control stuck closed (Bank 1)

The controller detected the Bank 1 intake manifold runner control in a closed position when a different state was expected.

Generic definition
P2004
P2015

Likely cause paths · unconfirmed

A possible intake runner or actuator movement issue

A runner, actuator, linkage, or intake deposit may affect the commanded position; the code does not identify which part is at fault.

  • Record when the warning and any power or idle change occur.
  • Do not move a linkage or remove intake parts.

A possible position sensor or control-circuit issue

A position signal, connector, wiring, or control issue may create a range/performance report.

  • Save companion intake or air-flow codes.
  • Record freeze-frame and any available runner-position data.

Likely causes and repair directions are general, conditional orientation. The SAE citation supports the generic DTC definition only; it does not validate these causes, tests, repairs, or fitment to a particular vehicle.

Conditional likely repairs

A code describes a monitored condition; it does not prove a failed part. Use these directions only after confirming the cause.

If confirmed: A possible intake runner or actuator movement issue

If inspection and commanded-operation tests confirm a runner or actuator movement fault, repair the verified mechanism using the vehicle-specific procedure.

Evidence to confirm

  • The OEM test confirms that actual movement does not match commanded movement.
  • The required position and monitor checks pass after repair.

If confirmed: A possible position sensor or control-circuit issue

If circuit or feedback testing confirms an electrical fault, repair the isolated connector, wiring, or verified sensor cause.

Evidence to confirm

  • Circuit and live-data checks isolate the fault.
  • Commanded and reported positions agree during the prescribed verification.

Guided evidence checks

  1. 01

    Record what happened

    Note when the warning appeared, what the vehicle was doing, and any recent service or change. Do not deliberately recreate an unsafe symptom.

  2. 02

    Make only a safe visual check

    With the engine off and cool, note only obvious external damage or a disconnected plug if it is safely visible. Do not move linkages or reach into the intake.

  3. 03

    Preserve scan-tool evidence

    Qualified technician

    Save the code status, freeze-frame, and available runner-position or command data as displayed.

  4. 04

    Confirm the system path

    Qualified technician

    A qualified technician should compare command and feedback, inspect the actuator/linkage, and test the circuit using OEM information.

Code-specific symptom note

  • Code-specific symptoms are not verified by the cited definition. Record the driver’s actual observations separately.

This generic code reference is not an OEM procedure, does not confirm that a DTC applies to a particular make/model/engine, and is not a repair diagnosis. Follow vehicle-specific service information or consult a qualified technician.
