Abstract
A low pressure EGR regulating valve is driven by an electric actuator, and an output of the electric actuator is transmitted to an intake air throttle valve through a link device. An ECU executes a failure determination to determine presence of a failure in a case where a sensed opening degree, which is sensed with a low pressure EGR opening degree sensor, is other than an opening degree that corresponds to a maximum opening degree of the throttle valve limited by a mechanical stopper. The ECU executes the failure determination after the energization of the electric actuator is stopped in response to stopping of the engine.
