1. An actuator for a vehicle coolant control valve, the actuator comprising:
a drive unit to generate driving power;
an output unit to drive a control valve, which selectively opens/closes (“switches”) 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 filter EMC,
wherein the output unit includes:
an output gear that rotates around an output shaft by the driving power of the drive unit; and
an interference member, which is prepared to partially cover one surface of the output gear and to thus face the sensing unit and is communicated with rotation of the output gear, and
wherein the output gear and the interference member are made of different materials from each other.
