ABSTRACT:
A control apparatus is provided for a sealed fuel tank system which is applied to an engine including a throttle valve provided in an intake pipe, and which includes a vaporized fuel supply pipe that connects a fuel tank and the intake pipe, and a control valve that opens and closes the vaporized fuel supply pipe. The control apparatus includes a controller which maintains the control valve in an open state on the condition that a pressure in the fuel tank is equal to or higher than a reference determination pressure; and corrects an opening amount of the throttle valve to a value equal to a first control opening amount that is smaller than a required opening amount set based on an operating state of the engine by a first correction opening amount when the control valve is in the open state.
