P206E code meaning
Intake Manifold Tuning (IMT) Valve Stuck Open (Bank 2)
Powertrain system Generic code P20xx codes Check engine light
What P206E means
Reserved for engines whose second cylinder bank has its own intake manifold tuning valve, the flap that switches plenum volume or runner length for resonance charging. The code says the bank 2 flap was commanded shut but its position feedback still reports it open. No manufacturer documents P206E publicly; the GM and Ford tables checked cover only a single tuning valve, logged as P2070/P2071. By analogy with GM, a fault would be counted once the closed end stop is not reached for several seconds and confirmed on a second trip. CARB lists variable-length intake runner systems as monitored output components. The driver mostly notices a torque dip in one speed band; P206F is the reverse case, P2070 the bank 1 counterpart.
P206E 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 P206E
- Check engine light after two drives (manufacturer-dependent)
- Noticeably less pulling power in one rpm range
- Changed intake sound under acceleration
Common causes of P206E
- Most likelyFlap or shaft of the bank 2 tuning valve gummed up by oil vapour and carbon from crankcase ventilation
- PossibleBank 2 actuator motor or gear worn, cannot drive the flap into the closed stop
- PossibleLinkage between actuator and flap shaft detached or broken
- Less likelyEnd positions not relearned after actuator or manifold replacement
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P206E 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. |
| 6E | The exact fault in that area. |
What to do next
- Note P206E 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 P206E
What does P206E mean?
P206E means "Intake Manifold Tuning (IMT) Valve Stuck Open (Bank 2)". Reserved for engines whose second cylinder bank has its own intake manifold tuning valve, the flap that switches plenum volume or runner length for resonance charging. It is a generic code, so it means the same on every make.
Is it safe to drive with P206E?
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 P206E fail an emissions test?
Yes, it can. P206E 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 P206E 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 P206E 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.
