What Does P2006 Mean?
The intake manifold runner control valve for Bank 1 is stuck in the closed position. This prevents the valve from opening to optimize airflow at higher engine speeds.
Common Causes
35%
Carbon buildup preventing valve from opening
30%
Failed or seized runner control actuator
20%
Broken actuator linkage or mechanical obstruction
10%
Faulty position sensor providing incorrect feedback
5%
Wiring short circuit or PCM malfunction
Diagnostic Steps
1
Step 1: Inspect Bank 1 runner control valve for carbon deposits, physical binding, or mechanical damage
2
Step 2: Attempt to manually move runner control valve to check for freedom of movement
3
Step 3: Use bi-directional controls to command actuator open while monitoring position sensor feedback
4
Step 4: Test actuator motor or solenoid for proper voltage supply and ground when commanded
5
Step 5: Clean or replace runner control valve if carbon buildup is excessive
Estimated Repair Cost
$150 - $800
Parts + labor, varies by vehicle and location
The intake manifold runner control valve for Bank 1 is stuck in the closed position. This prevents the valve from opening to optimize airflow at higher engine speeds.
The most common cause of P2006 (Intake Manifold Runner Control Stuck Closed Bank 1) is: Carbon buildup preventing valve from opening
Typical repair costs for P2006 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle is safe to drive but may experience reduced high-RPM power, hesitation during acceleration, and decreased fuel economy. Low-speed operation typically unaffected.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2006 to identify the root cause.
