Vehicle having an integrated coolant control valve and a control method for same

A vehicle provided with an integrated coolant control valve, the vehicle comprising:

• an integrated coolant control valve that includes a plurality of coolant passages for supplying coolant to a plurality of heat exchange elements having a radiator, a plurality of valves for selectively opening the plurality of coolant passages, respectively, a cam on which a plurality tracks are formed for pushing the plurality of valves to be opened, respectively, and a motor for selectively rotating the cam;
• a vehicle operation state detecting portion that includes a coolant temperature sensor for measuring a coolant temperature and outputting a corresponding temperature output signal, a position sensor for measuring a rotation position of the cam and outputting a corresponding position output signal, and an accelerator pedal sensor for measuring an operation angle of an accelerator pedal and outputting a corresponding angle output signal;
• an engine that includes an injector for injecting fuel;
• and
• a controller for controlling operations of the integrated coolant control valve and the injector according to the output signals of the vehicle operation state detecting portion,
• wherein the controller performs a fault diagnosis of the integrated coolant control valve, determines whether the position sensor is faulty when the controller determines that the integrated coolant control valve is faulty, and moves the cam to a maximum position by operating the integrated coolant control valve when the controller determines that the position sensor is faulty.
