P206EIntake Manifold Tuning (IMT) Valve Stuck Open (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
- 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.
- What you may notice
- Check engine light after two drives (manufacturer-dependent)
- Noticeably less pulling power in one rpm range
- Changed intake sound under acceleration
- Likely causes
- 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
- RareEnd positions not relearned after actuator or manifold replacement
- 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
