Disclosed herein are a brake fluid pressure sensor validity determination device and a determination method thereof. According to an embodiment of the present disclosure, the brake fluid pressure sensor validity determination device and the determination method thereof includes an inputter configured to receive a brake fluid pressure sensor value sensed by a brake fluid pressure sensor and receive a motor position sensor value sensed by a motor position sensor, an estimator configured to estimate a brake fluid pressure value on the basis of the motor position sensor value when the motor position sensor has not failed; and a determiner configured to determine whether the brake fluid pressure sensor has failed, determine whether the motor position sensor has failed when the brake fluid pressure sensor has not failed, and determine a validity of the brake fluid pressure sensor by comparing the estimated brake fluid pressure value with a brake fluid pressure sensor value.
