P207DIntake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit High (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
- The bank 2 valve position signal reads above the highest value the controller accepts. Electrically that points at a broken sensor ground or a short from the signal to a supply voltage. There is no published manufacturer use of P207D; it mirrors GM's bank 1 code P2078, where 5 % or less counts as high due to the reversed scale, while GM's 2023/2024 logic compares the raw voltage with about 4.8 V. An open ground often comes from heat-damaged connectors on the rear bank, so inspect the plug before ordering a new actuator. Unlike P207B, a high code says nothing about the flap mechanics; the valve may move correctly while its feedback is simply not readable.
- What you may notice
- Check engine light (manufacturer-dependent)
- No driveability change in most cases
- Likely causes
- LikelySensor ground open at a heat-damaged connector
- PossibleSignal wire shorted to 5 V or battery voltage
- RareBank 2 actuator electronics defective
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Easy · Often possible to do yourself.Typical cost: €20 – €400
