P206FIntake Manifold Tuning (IMT) Valve Stuck Closed (Bank 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- Here the bank 2 tuning valve ignores an open request: the engine computer asks it to swing to the open end stop, yet the feedback still shows the closed position. The code only makes sense on a V-engine with a separately switched flap per bank, and no manufacturer publishes it; GM and Ford describe a single valve and use P2071 for the stuck-closed case. GM counts that fault when the open position is missing after at least 5 s and sets it as Type B. Electrical faults in the drive circuit belong to P0663 and onward, position sensor faults on bank 2 to P207A to P207E. A flap jammed shut usually costs top-end power more than low-speed torque, so the car may feel flat at higher revs; P206E is the opposite direction.
- What you may notice
- Engine feels flat at high rpm
- Check engine light (manufacturer-dependent)
- Barely noticeable at moderate driving
- Likely causes
- LikelyBank 2 flap seized in its closed position by deposits or a dry shaft bearing
- PossibleBank 2 actuator internally defective, no longer produces the opening torque
- RareOn vacuum-operated designs a leaking hose or check valve leaves the actuator without vacuum
- RareBroken flap seal or foreign object blocking the flap travel
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €60 – €500
