    • An abnormality diagnosis apparatus for an evaporative emission control system which includes a fuel tank, a canister for adsorbing evaporative fuel generated in the fuel tank, an evaporative fuel passage connecting the fuel tank and an intake system, a first control valve interposed in a charging passage, a second control valve interposed in a purge passage, a third control valve interposed in a vent passage, and a fourth control valve interposed in the evaporative fuel passage for opening and closing the evaporative fuel passage. An abnormality of the evaporative emission control system is diagnosed based on a detected pressure in the fuel tank. During the abnormality diagnosis, the fourth control valve is controlled to be maintained in a closed state, and the abnormality diagnosis is performed by changing an open or closed state of at least one of the first, second and third control valves without opening the first and third control valves simultaneously.
