ABSTRACT:
A system for calibrating production throttle bodies in which a throttle body (18) is mounted in a fixture (16) and light is transmitted by a light source (12) through the throttle body main bore (20) onto a translucent screen (22). A camera (14) senses the light regions (34) and transmits the information to a controller (26), which calculates the angular position of the throttle valve (32).
