ABSTRACT:
In a throttle body fuel injection assembly, the rotor of a throttle position sensor is mounted directly on the throttle shaft and the sensor housing is supported on the rotor, thereby providing a compact sensor construction. A spring in the sensor tends to impart relative rotation between the rotor and the housing, biasing the housing toward engagement with the throttle body. With this invention, the housing rotates with the rotor away from engagement with the throttle body if the spring does not impart relative rotation between the housing and the rotor.
