P207CIntake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Low (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
- Low signal on the position feedback of the bank 2 tuning valve: the controller sees a value below the window it accepts. Typical electrical causes are the signal shorted to ground or a missing 5 V supply. No manufacturer publishes P207C. Its bank 1 equivalent P2077 is well documented at GM, where the limit is given in percent and the scale runs backwards (95 % or more counts as low), and FCA cites P2077 for the 3.5L V6 manifold tuning valve; a bank 2 application would follow the same pattern. Ground faults can also kill other sensors on the shared 5 V circuit, so if several sensor codes appear together, look for the common reference first. P207D is the high-side fault.
- What you may notice
- Check engine light (manufacturer-dependent)
- Other 5 V sensor codes at the same time
- Likely causes
- LikelyBank 2 signal wire shorted to ground
- PossibleShared 5 V reference pulled down or open
- RareInternal short in the bank 2 sensor
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
