An apparatus and a method for diagnosing a failure of an ultrasonic detector in a manner that diagnoses whether a failure has occurred in the ultrasonic detector by determining whether a surge voltage is generated based on a waveform received by a receiver of the ultrasonic detector after activation of a transmitter of the ultrasonic sensor, may include an ultrasonic detector transmitting and receiving an ultrasonic wave; a voltage detector measuring a voltage of the received ultrasonic wave; and a controller determining whether a surge voltage is generated based on the measured voltage, and diagnosing whether a failure has occurred in the ultrasonic detector according to whether the surge voltage is generated.
