Abstract
An apparatus for a vehicle includes a cooling fan installed in an engine compartment of the vehicle. A fan motor is connected with the cooling fan to drive the cooling fan. A state detector is configured to detect state data, and a controller is configured to control the cooling fan based on the state data when an intake temperature is within a predetermined range, to determine whether the state data satisfies a decision reference condition, and to lock the fan motor according to a change rate of air conditioner refrigerant pressure during a measurement time when the state data satisfies the decision reference condition.
