According to a preferable embodiment of the present invention, a failure determination method of an electronic valve comprises: a maximum supply current calculation step of calculating the maximum supply current by using current data obtained from an electronic valve; a compensation value computation step of computing a compensation value based on coefficients of a pre-generated prediction regression model and specific temperature; an integrity factor computation step of computing an integrity factor by using the compensation value and the maximum supply current; and a failure determination step of determining whether the electronic valve has a fault using the integrity factor and a preset failure threshold.
