装置。 In a wheel speed sensor that emits a wheel speed signal according to the number of teeth of a tone wheel attached to a wheel, a predetermined number of times the signal period of the output signal from the wheel speed sensor is twice or more of the immediately preceding signal period. A failure detection device for a wheel speed sensor, characterized in that the wheel speed signal system is provided with a determination circuit that determines that the tone wheel is missing teeth when the above is repeated.
