P207C Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Low (Bank 2)
IMT position sensor at bank 2 reads below lower plausibility — short to ground. The intake manifold runner control (IMRC) flaps tune intake geometry for filling efficiency across the rpm range; stuck flaps cost part-load torque and can set lean codes.
Is it safe to drive with P207C?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelyShort to ground
- Less likelyConnector pins corroded - high contact resistance
- Less likelyHarness chafing through insulation
