P2006 Technical Description
Intake Manifold Runner Control Stuck Closed Bank 1
If you’re seeing the P2006 trouble code in your car, you’re likely wondering what it means and how to fix it.
I’ve encountered this issue before, so I know how to handle it.
In this guide, I’ll explain the meaning, symptoms, causes, and fixes for the P2006 code, so you can get your car back in shape.
Let’s jump right into it.
Key Takeaways
- P2006 means the intake manifold runner control (IMRC) on bank 1 is stuck closed.
- Common symptoms include rough idle, decreased performance, and a check engine light.
- Causes include carbon buildup, faulty IMRC components, and electrical issues.
- Diagnose by inspecting the IMRC system, checking wiring, and testing components.
- Fixes involve cleaning the intake manifold, repairing or replacing faulty parts, and checking for vacuum leaks.
- Clearing the code and a test drive confirms the issue is resolved.

What Does P2006 Trouble Code Mean?
The P2006 trouble code stands for “Intake Manifold Runner Control Stuck Closed Bank 1.”
This code indicates that the intake manifold runner control (IMRC) for bank 1 is stuck in the closed position.
The IMRC system helps control the airflow through the intake manifold. It adjusts the air intake to optimize performance and efficiency.
When the IMRC is functioning properly, it opens and closes the intake manifold runners to manage airflow based on engine speed and load.
When stuck closed, it disrupts this balance, leading to performance issues.
Bank 1 refers to the side of the engine where cylinder 1 is located. In a V-engine, it’s one of the two cylinder banks.
The IMRC system on this bank is not operating as it should, causing the P2006 code to trigger.
This code often means that the flaps in the intake manifold are not moving as required.
This can be due to mechanical issues like carbon buildup, which can cause the flaps to stick. It could also be an electrical issue, such as a faulty IMRC solenoid, actuator, or wiring problem.
When the IMRC is stuck closed, your engine may not get the right amount of air. This can result in a rough idle, reduced power, and increased fuel consumption.
Ignoring this issue can lead to further engine problems and decreased performance over time.
In summary, the P2006 code indicates that the intake manifold runner control system on bank 1 is stuck closed, affecting your engine’s airflow and performance.
Addressing this issue promptly can help maintain your vehicle’s efficiency and prevent further damage.
P2006 Trouble Code Symptoms
If your car has a P2006 trouble code, you might notice several symptoms indicating an issue with the intake manifold runner control. Here are the common signs:
- Rough idle
- Decreased engine performance
- Reduced fuel efficiency
- Check Engine Light (CEL) illuminated
- Hesitation or stumbling during acceleration
- Increased emissions
P2006 Trouble Code Causes
The P2006 trouble code can be triggered by several underlying issues. Here are the common causes:
- Carbon buildup in the intake manifold
- Faulty intake manifold runner control (IMRC) solenoid
- Malfunctioning IMRC actuator
- Broken or disconnected IMRC linkage
- Electrical issues such as damaged wiring or connectors
- Vacuum leaks in the intake manifold system
How To Fix A P2006 Trouble Code
Fixing a P2006 trouble code involves diagnosing the root cause and then performing the necessary repairs. Here’s how to go about it:
1. Scan the Code
Use an OBD-II scanner to confirm the P2006 code. This will help you verify the issue and check for any other related codes.
2. Inspect the IMRC System
Begin by inspecting the intake manifold runner control (IMRC) system for visible issues. Look for broken or disconnected linkages, and check for carbon buildup around the IMRC flaps.
3. Check the IMRC Actuator and Solenoid
Test the IMRC actuator and solenoid to ensure they are functioning correctly. You can use a multimeter to check for proper voltage and resistance.
4. Examine the Wiring and Connectors
Inspect the wiring and connectors associated with the IMRC system. Look for any signs of damage, corrosion, or loose connections. Repair or replace any damaged components.
5. Clean the Intake Manifold
If you find carbon buildup, clean the intake manifold thoroughly. Use an appropriate cleaner to remove carbon deposits from the IMRC flaps and surrounding areas.
6. Test for Vacuum Leaks
Check for vacuum leaks in the intake manifold system. Use a smoke test or spray carburetor cleaner around the manifold to identify any leaks. Repair any found leaks.
7. Replace Faulty Components
If the IMRC solenoid or actuator is faulty, replace them. Make sure to use high-quality parts to ensure long-term reliability.
8. Clear the Code and Test Drive
After making the necessary repairs, use the OBD-II scanner to clear the P2006 code. Then, take your vehicle for a test drive to ensure the issue is resolved and the code does not reappear.
By following these steps, you can effectively diagnose and fix the P2006 trouble code, restoring your vehicle’s performance and efficiency.
Conclusion
Now that you know what the P2006 trouble code means and how to fix it, you’re all set.
