P2010 — Intake Manifold Runner Control Circuit High Bank 1

Manufacturer-specificPowertrain (engine & transmission)

The engine computer has detected that the voltage signal from the Intake Manifold Runner Control (IMRC) circuit on Bank 1 is higher than the expected range. This typically indicates an electrical fault in the actuator or a mechanical failure preventing the runners from moving to the commanded position.

Symptoms

What causes it — most likely first

1. Failed IMRC Actuator

Internal electrical failure or a short circuit within the actuator motor or solenoid.

2. Broken Linkage or Vacuum Line

A snapped plastic linkage or ruptured vacuum hose prevents the runners from moving, causing a position mismatch.

3. Wiring Harness Damage

Frayed, melted, or chafed wires causing a short to a power source (circuit high).

4. Corroded Connectors

Moisture or debris in the electrical connector creating high resistance or intermittent connectivity.

5. Faulty Engine Control Module (PCM)

An internal failure in the PCM's driver circuit for the IMRC system.

How it's diagnosed

  1. Perform a visual inspection of the IMRC linkages and vacuum lines for breaks or disconnections.
  2. Verify the physical operation of the runners by manually attempting to move the linkage (if accessible).
  3. Check the electrical connector for corrosion or loose pins.
  4. Use a multimeter to test the actuator's resistance and ensure the wiring is not shorted to voltage.
  5. Utilize a bidirectional scan tool to command the IMRC actuator and observe its response.
  6. Test the signal voltage at the PCM connector to determine if the fault is in the actuator or the computer.

Frequently asked

Can a broken plastic piece cause this electrical code?

Yes. If the mechanical linkage breaks, the actuator may move beyond its intended range or fail to reach the target position, leading the PCM to trigger a circuit high code.

Is it safe to drive with a P2010 code?

The vehicle is generally drivable, but engine performance will be suboptimal across certain RPM ranges, and fuel economy will likely decrease.

Should I replace the PCM to fix this issue?

No. It is very uncommon for the PCM to be the cause of a P2010 code; the issue is almost always located in the actuator, the linkage, or the wiring.
