Abstract
A vaporized fuel processing apparatus has a fuel tank, a canister configured to adsorb vaporized fuel and connected to an internal combustion engine, a vapor path connecting the fuel tank to the canister, a closing valve having a stepping motor and configured to open and close the vapor path, and an electric control unit configured to cause the closing valve to an initial position in order to initialize the closing valve. The electric control unit is configured to determine whether it is in a predetermined initialization permission time when the initialization of the closing valve does not adversely affect running of the internal combustion engine. When it is determined that it is in the predetermined initialization permission time, the electric control unit is configured to output signals to start the initialization of the closing valve.
