P207E
Intake Manifold Tuning (IMT) Valve Position Sensor/Switch Circuit Intermittent (Bank 2)
IMT position sensor at bank 2 signal is unstable — connector or harness issue. 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.
