Intake Manifold Runner Position Sensor/Switch Range/Performance (Bank 1)
The IMRC position sensor on bank 1 reports a value, but it does not match the commanded flap state — for example, the flap is commanded closed yet the sensor still reads open. Common on engines where the connector pin clip wears out and the sensor reads erratic positions.
