Abstract A control device for a sucked air quantity of an engine comprises an accelerator pedal opening degree sensor for detecting an opening degree of an accelerator pedal; a throttle valve opening degree sensor for detecting an opening degree of a throttle valve; a throttle valve actuator for controlling the opening degree of the throttle valve in accordance with outputs of both the accelerator pedal opening degree sensor and the throttle valve opening degree sensor; a first fully-closed state detecting switch for detecting a fully-closed state of the accelerator pedal; a second fully-closed state detecting switch for detecting a fully-closed state of the throttle valve; and an abnormality determining means for determining that the control device for a sucked air quantity is abnormal when the throttle valve is not in the fully-closed state in case that the accelerator pedal is in the fully-closed state.
