It is determined that there is an abnormality in crank pulses when the situation, in which a regular pitch crank pulse counter T does not reach a prescribed value To between irregular pitch crank pulses (interval abnormality), repeatedly occurs at least a prescribed value CNT0 times, when an irregular pitch is not detected for a prescribed period of time for the crank pulse counter T to count up to TMAX or longer, or when the situation, in which a prescribed number or more of clank pulses are not detected for a prescribed period of time, repeatedly occurs at least a count-up value KMAX of times.",
