The engine code P2006 means the control flap on the intake manifold runner is stuck in the closed position
Definition: Intake manifold runner control stuck closed bank 1
The P2006 engine fault code indicates a problem with your car’s intake air process—specifically the manifold runner control flap for engine bank 1. The intake manifold runner control (IMRC) system improves the engine airflow process, which boosts engine performance and efficiency.
, total parts and labor can cost anywhere between $400 and $600.
What can cause the P2006 engine code?
If the P2006 engine code is displayed on your OBD-II, your intake manifold runner control flap for engine bank 1 is probably stuck in the closed position. Other possible causes of this DTC include:
Faulty intake manifold runner control IMRC actuator
The intake manifold runner control actuator harness is open or shorted
You might not see any visible symptoms accompanying the P2006 OBD-II trouble code other than a lit check engine light. You may notice other symptoms including:
Slow or sluggish acceleration
Rough or fluctuating idle
Rich exhaust
Diminished fuel efficiency
Engine surge
If your intake manifold is stuck in the closed position, your car might start easily and accelerate smoothly, but after driving for a few minutes your engine will surge in speed or misfire. That’s due to carbon buildup.
The P2006 engine code affects your car’s driveability and should be dealt with promptly. If left unfixed, a closed intake manifold runner control flap tarnishes your engine’s airflow and fuel mixture leading to performance problems and further damage to your engine.
The P2006 engine code is not a simple fix—only DIY if you have the skills
If you plan to fix the P2006 engine code yourself, it’s important that you properly diagnose the cause of the code before you attempt any repairs. Check the freeze frame data, and then inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connectors’ pins.
Depending on the cause of the engine code, there are a number of repairs you may need to do including:
Wiring harness repair
Electrical connection fixed
Intake manifold runner position and position sensor fixed
Intake manifold runner control solenoid replaced
Intake manifold runner unclogged or replaced
Intake manifold runner control flap replaced
If you are not sure what is causing the P2006 engine code,
If you decide to replace the intake manifold runner at home, you’ll need to follow these steps:
Locate the intake manifold runner control in your engine. You might have to remove a few plastic covers before you see it.
Disconnect the intake manifold runner control. You may need to disconnect the vacuum lines and electrical connections to do this.
Replace the old intake manifold runner control with the new one. To do this you’ll need to unbolt the IMRC from the engine.
After you’ve properly replaced the intake manifold runner control, clear any codes on the engine computer and test drive your car to evaluate its performance.
