The present invention relates to a steering angle sensor failure detection apparatus and a control method thereof. The steering angle sensor failure detection apparatus according to one embodiment comprises: a main gear rotating together with a steering wheel; a first sub-gear and a second sub-gear respectively meshed with the main gear while having a predetermined gear ratio with the main gear; a steering angle sensor including a first Hall IC chip detecting an angle of the first sub-gear and a second Hall IC chip detecting an angle of the second sub-gear; and a control unit determining a failure of the steering angle sensor based on a first angle difference between a current time point and a previous time point of the first sub gear angle detected by the first Hall IC chip, and a second angle difference between a current time point and a previous time point of the second sub gear angle detected by the second Hall IC chip. One aspect of the disclosed invention is to provide a steering angle sensor failure detection apparatus, which can more effectively detect the failure due to gear deformation or damage to the steering angle sensor, and the control method thereof.
