P206F code meaning
Intake Manifold Tuning (IMT) Valve Stuck Closed (Bank 2)
Powertrain system Generic code P20xx codes Check engine light
What P206F means
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.
P206F at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P206F
- Engine feels flat at high rpm
- Check engine light (manufacturer-dependent)
- Barely noticeable at moderate driving
Common causes of P206F
- Most 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
- Less likelyOn vacuum-operated designs a leaking hose or check valve leaves the actuator without vacuum
- Less likelyBroken flap seal or foreign object blocking the flap travel
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P206F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 0 | Area: fuel and air metering and auxiliary emission controls. |
| 6F | The exact fault in that area. |
What to do next
- Note P206F and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P206F
What does P206F mean?
P206F means "Intake Manifold Tuning (IMT) Valve Stuck Closed (Bank 2)". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P206F?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P206F fail an emissions test?
Yes, it can. P206F is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P206F to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P206F clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
