Abstract
An electronic throttle control system with a housing having a motor, throttle valve and gear mechanism. The throttle valve is attached to a throttle body shaft which is mounted in bearings in the housing. An axial spring clip mechanism mounted on the throttle body shaft preloads the bearings and eliminates undesired axial and radial movement of the shaft which could adversely affect the movement of the throttle valve and the sensing of its position.
