The error Code P2006 signals a common issue: the variable tumble control system (VTCS) shutter valve is stuck in the closed position. For DIY mechanics, especially those who’ve worked on their intake manifold, this problem is often encountered. This code typically points to a small, fragile plastic component within the VTCS mechanism. While dealerships might suggest a costly intake manifold replacement, a simple, free fix exists. This guide provides a step-by-step solution to clear the P2006 code without spending any money.
To begin this repair, you’ll need to access the VTCS actuator area. Start by removing the engine cover. For easier access, removing the top mount intercooler (TMIC) and intake is advisable, though not strictly mandatory.
You will then see a mounting plate secured with two wiring harnesses. While disconnecting these harnesses can provide more room, it’s possible to complete the repair using long-handled tools like screwdrivers, ratchets with extensions, and pliers.
Locate the two 8mm bolts holding the mounting plate. The first bolt is clearly visible on top.
The second 8mm bolt is positioned on the right side of the head.
Once the plate is removed, you’ll be able to see the likely culprit: the broken plastic piece of the VTCS actuator.
The VTCS sensor, responsible for triggering the P2006 code, is attached with two Phillips head screws. Remove only the top screw.
After removing the top screw, gently bend the entire sensor bracket forward. It should bend easily. Position it directly on top of the actuator plunger so it’s consistently depressed.
Now, whenever the actuator moves, the sensor can move freely, resolving the stuck valve signal.
Reinstall the mounting plate and components in reverse order. This simple bend effectively bypasses the broken plastic piece, resolving the P2006 code and saving you the expense of a new intake manifold. Enjoy driving without the check engine light!
