Abstract:
A vehicle includes a transmission, a motor, and at least one controller. The motor is configured to be selectively coupled to the transmission. The at least one controller is programmed to output a fault for a coil temperature sensor of the motor based on an oil temperature of the transmission, a phase current of the motor, and a temperature change in a coil of the motor.
