When the motor power inverter (MPI) module temperature is a specified value or more in the power save mode, the MPI module temperature decreases if the MPI module cooling system is normal. The MPI module temperature sensor stuck failure is detected by comparing the MPI module temperature decrease over a specified time to a specified value.
