Abstract
An actuator for a vehicle coolant control valve according to the present invention includes: a drive unit to generate driving power; an output unit to drive a control valve, which selectively opens/closes a coolant flow for a vehicle using the driving power provided by the drive unit; and a sensing unit to sense an output condition of the output unit, wherein the sensing unit is provided with a position sensor to sense a position of the output unit and an electro-magnetic compatibility (EMC) filter to filer EMC. According to the above configuration, a single printed circuit board may have a function of an EMC board and a function of a sensor board, which are advantageous in ensuring space and design freedom to thus contribute to improvement of control quality.
