Intake Manifold Runner Control Stuck Closed Bank 2
The P2007 code indicates that the intake manifold runner control (IMRC) system for bank 2 is stuck in the closed position. This system uses flaps or valves inside the intake manifold to optimize airflow at different engine speeds. When stuck closed, airflow is restricted, reducing engine performance and fuel efficiency. The issue is often caused by carbon buildup, a faulty actuator, or a broken linkage.
01. Most Common Causes
- Carbon buildup on the intake manifold runner flaps
- Faulty IMRC actuator or motor
- Broken or stuck linkage/rod
- Wiring or connector issues to the actuator
02. Symptoms You Will Notice
- Check Engine Light on
- Reduced engine power and acceleration
- Poor fuel economy
- Rough idle or hesitation
03. Step-by-Step Diagnosis
Step 1: Scan for codes and verify P2007 is present.
Step 2: Visually inspect the IMRC actuator and linkage for damage or binding.
Step 3: Use a scan tool to command the IMRC open/closed and observe actuator movement.
Step 4: Check wiring and connectors for corrosion or breaks.
Step 5: Remove intake manifold to inspect flaps for carbon buildup if necessary.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive for extended periods as it can cause reduced performance and potential engine damage due to improper air-fuel mixture.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, depending on whether cleaning or replacement of the intake manifold or actuator is needed.
