PROBLEM TO BE SOLVED: To provide an evaporated fuel processing apparatus capable of further appropriately decreasing the pressure in a fuel tank than conventional ones.SOLUTION: An ECU calculates a differential pressure dP by subtracting a canister internal pressure from a tank internal pressure (step S2). When a determination is made that a purge operation is being performed by a purge mechanism (step S3), the ECU determines whether the differential pressure dP is lower than a pressure difference Pb (step S4). When a determination is made that the differential pressure dP is not lower than the pressure difference Pb, the ECU inhibits execution of depressurization processing (step S6). |
