Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit High (Bank 2)
IMT position sensor at bank 2 reads above upper plausibility — open signal or short to B+. 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.
