PROBLEM TO BE SOLVED: To properly detect an abnormality of an intake-air temperature sensor even though an engine is intermittently stopped on a vehicle mounted with a heating wire air flow meter while an ignition switch is turned on.SOLUTION: In an abnormality determination device for determining the presence or absence of an abnormality of an intake-air temperature sensor according to whether or not the intake-air temperature detected by an intake-air temperature sensor during the stop of an engine varies by exceeding a designated quantity of a variation at a designated period, when a heating wire air flow meter is heated during the stop of the engine, a designated quantity of a variation is set up to be larger in comparison with the case that the heating wire air flow meter is not heated during the stop of the engine, and/or the designated period is set up to be shorter. |
