PROBLEM TO BE SOLVED: To provide an abnormality determination device capable of determining the abnormality of a temperature detecting means for detecting a temperature related to the operation of an engine at start-up even though the abnormality occurs in an engine off timer. SOLUTION: The abnormality determination device includes a timer means 30 for determining an engine stop elapse time; an abnormality determination means 32 comparing any one of the difference between a detected temperature t1 by a temperature detecting means 21 and the predetermined referential temperature, and the difference between the detected temperatures by two optional temperature detecting means with a first determination threshold value when the engine stop lapse time determined by the timer means 30 is the same as or longer than the predetermined time; and setting means 27 for setting a second determination threshold value when an abnormality memorizing means 33 memories an abnormality of the timer means 30. The abnormality determination means 32 compares the detected temperature t1 or the difference with the second determination threshold value set by the setting means to execute the abnormality determination of the temperature detecting means 21 when the abnormality memorizing means 33 memorizes the abnormality of the timer means 30.
