P2007 Code: Intake Manifold Runner Stuck Closed (Bank 2)
Is your car struggling to pass people on the highway? Does the engine feel choked when you rev it high? If you have code P2007, one side of your engine is literally asthmatic. The intake flaps on Bank 2 are stuck shut, blocking the airflow needed for peak performance.
What Does P2007 Mean?
P2007 stands for "Intake Manifold Runner Control Stuck Closed Bank 2."
Your engine uses variable intake runners to optimize power. At high RPMs, these flaps should open to let air rush in. P2007 means the computer commanded them to open, but the sensor detected they stayed closed on Bank 2 (the side opposite Cylinder #1).
Since the engine can't breathe deeply, you will experience:
- Significant power loss at highway speeds.
- Hesitation during acceleration.
- Potential engine misfires (due to rich fuel mixture).
🔗 Related Codes: P2006 & P2005
It is very common to see P2007 accompanied by other codes. Knowing the difference helps you pinpoint the broken part:
- Have P2006 too? That means both sides are stuck closed. This usually points to a shared part like a main solenoid or vacuum line. Read our guide on P2006 here.
- Have P2005? That means Bank 2 is stuck Open (opposite of P2007). See why P2005 kills low-end torque here.
Why Is Bank 2 Stuck Closed?
Diagnosing P2007 is often easier than P2006 because it isolates the problem to one side of the engine. The most common causes are:
1. Vacuum Line Failure (Bank 2 specific)
Many systems use vacuum actuators to pull the flaps open. If the specific rubber hose leading to the Bank 2 actuator is cracked, pinched, or disconnected, that side won't open, while Bank 1 might still work fine.
2. Broken Actuator Linkage
This is notorious on Mercedes-Benz and Audi engines. The plastic arm connecting the vacuum motor to the metal flap snaps. The motor moves, but the flap stays shut.
3. Carbon Sludge
On GDI (Direct Injection) engines, carbon buildup can physically glue the flaps shut. If the actuator tries to push them open but can't overcome the resistance, it triggers P2007.
How to Verify the Fault with iCarsoft CR Ultra P
Replacing an intake manifold is expensive and time-consuming. You need to be 100% sure before you start unbolting things. Use the Active Test feature on your scanner.
The "Bank 2" Isolation Test:
- Hook Up: Connect the CR Ultra P and turn the key to ON (Engine Off).
- Select Data: Go to Live Data and select "IMRC Monitor Bank 2" and "IMRC Monitor Bank 1."
- Active Test: Go to the Actuation Test menu. Command the IMRC system to OPEN.
-
Compare:
- If Bank 1 switches to "OPEN" but Bank 2 stays "CLOSED," you have confirmed the electrical signal is good, but the mechanical part on Bank 2 is failed.
- If you hear a vacuum hiss near Bank 2 during the test, you have found a leak.
Isolate the Problem Instantly
Generic scanners can't separate Bank 1 from Bank 2. The iCarsoft CR Ultra P gives you manufacturer-level control to test each actuator individually.
Frequently Asked Questions
Is P2007 expensive to repair?
It depends. If it is just a cracked vacuum hose ($10) or a broken plastic clip ($30), it is cheap. However, if the flaps are seized internally inside the manifold (common on VW/Audi 2.0T), you may need to replace the entire intake manifold assembly ($400-$900).
Will P2007 clear itself?
No. This is a "hard fault." The computer constantly monitors the flap position. Even if you clear the code with a scanner, it will return the moment you rev the engine past 2,500 RPM if the mechanical issue isn't fixed.
Can I use WD-40 to fix stuck runner flaps?
If the sticking is external (on the linkage), yes, a lubricant might help temporarily. But if the sticking is internal due to heavy carbon buildup, WD-40 won't reach it. You will likely need a physical cleaning or walnut blasting.
