    摘要: The detection of a valve-opening starting position of an exhaust gas recirculation (EGR) valve which is disposed in an exhaust gas recirculation system is surely made, and the amount of movement of a motor shaft of an electric motor in a valve-closing direction is restricted. In this manner, the motor shaft is prevented from striking a stopper which restricts the operating range of the electric motor.
