A wireless control system of a throttle valve for automobiles including a throttle body having a cylindrical path guiding a flow of air; a valve shaft, passing through the center of the throttle body at a right angle to the path of the throttle body; a valve, joined with valve shaft, controlling the amount of air passing through the path and is slightly smaller than and matching the shape of the path; a permanent magnet, disposed at a right angle to one end of the valve shaft, which protrudes outward from the throttle body; an electromagnet fixed on the outside of the throttle body providing the magnetism to the permanent magnet; a return spring, disposed on the other end of the valve shaft which also protrudes out of the throttle body, the return spring providing return rotation force to the valve; and an electronic control unit, connected with a terminal of the electromagnet and which supplies an electrical current thereto when the emission of magnetism by the electromagnet is need.
