ABSTRACT:
A sensor for a throttle control device. The throttle control device includes a throttle body. A throttle valve is disposed within an intake air channel defined within the throttle body. A speed or gear reduction mechanism is coupled between a motor and the throttle valve. A sensor detects the rotational position, i.e., the rotational angle, of the motor and has a movable section and a fixed sensing section. The movable section is attached to a rotary shaft of the motor, so that the movable section rotates as the rotary shaft rotates. The fixed sensing section is mounted to the throttle body and is disposed within the movable section. By detecting the rotation of the motor a computing section can accurately determine the degree of opening of the throttle valve. The sensor outputs the degree of opening of the throttle valve.
