P2007 — Intake Manifold Runner Control Stuck Closed Bank 2

Manufacturer-specificPowertrain (engine & transmission)

P2007 indicates that the powertrain control module (PCM) has detected the intake manifold runner control (IMRC) for bank 2 is stuck in the closed position. This affects airflow into the engine, potentially reducing performance and efficiency.

Symptoms

What causes it — most likely first

1. Faulty intake manifold runner control actuator

The actuator motor or mechanism may fail due to wear, corrosion, or electrical issues, preventing it from opening the runner.

2. Stuck or binding intake manifold runner

Carbon buildup, debris, or mechanical wear can cause the runner flap or valve to seize in the closed position.

3. Wiring or connector issues

Damaged, corroded, or loose wiring or connectors between the PCM and the IMRC actuator can disrupt signal or power delivery.

4. Vacuum leak or failed vacuum supply

If the system uses vacuum actuation, a leak or failed vacuum line can prevent the runner from opening properly.

5. Faulty intake manifold runner position sensor

A failed or misaligned position sensor may send incorrect feedback to the PCM, triggering the code.

6. PCM software or control issue (rare)

While uncommon, a PCM software glitch or internal fault could incorrectly flag the IMRC as stuck closed. This is a last-resort diagnosis.

How it's diagnosed

  1. Retrieve and confirm the P2007 code using an OBD-II scanner, checking for related codes (e.g., vacuum or electrical issues).
  2. Visually inspect the IMRC actuator, runner mechanism, and linkage for signs of binding, corrosion, or damage. Manually test runner movement if accessible.
  3. Check wiring and connectors between the PCM and IMRC actuator for damage, corrosion, or loose connections. Test for proper voltage and ground signals.
  4. If the system uses vacuum actuation, inspect vacuum lines for leaks, blockages, or failed components (e.g., solenoids, diaphragms).
  5. Test the IMRC actuator and position sensor using a multimeter or scan tool to verify proper operation and feedback signals.
  6. If all other components check out, consider PCM testing or reflashing, but only after ruling out mechanical and electrical causes.

Frequently asked

Is the PCM usually the cause of P2007?

No. While the PCM monitors the IMRC system, the code is almost always caused by a mechanical or electrical failure in the actuator, runner, or wiring. PCM replacement is rarely necessary.

Can I drive with P2007?

You can drive short distances, but prolonged driving may reduce performance, fuel efficiency, and increase emissions. Address the issue promptly to avoid potential engine strain.

Why does the runner get stuck closed?

Common reasons include carbon buildup, debris, or wear in the runner mechanism, or failure of the actuator motor or vacuum system that controls it.

Will cleaning the runner fix P2007?

If the runner is stuck due to carbon or debris, cleaning may resolve the issue. However, if the actuator or linkage is damaged, cleaning alone won’t fix the problem.
