P207BIntake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Range/Performance (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
- On bank 2, the valve feedback is electrically valid yet does not match what the flap should be doing, for instance it changes too slowly, sticks at an intermediate value or disagrees with the commanded state. No manufacturer documents P207B. The closest documented logic is GM's bank 1 code P2076, which fails the actuator learn sweep when the reported position lingers inside the 5-35 % band for five seconds, or when learning restarts ten times in one key cycle. A plausibility code like this often points at mechanics rather than electrics: a flap that binds or a slipping coupling falsifies the movement profile even with an intact sensor. Compare with P206E/P206F, which judge the end positions of the same flap.
- What you may notice
- Check engine light (manufacturer-dependent)
- Possibly uneven power delivery
- Likely causes
- LikelyBank 2 flap binding, movement profile does not match the command
- PossibleCoupling between sensor shaft and flap slipping
- RareSensor characteristic drifted with age and heat
- 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 – €450
