ABSTRACT:
A method of assembling an actuating lever (10) to a potentiometer (12) for use in electronic engine control systems for internal combustion engines as a throttle position sensor to generate electrical signals indicating the angular position (A.degree.) of the throttle blade. In such systems, there is usually one known or "home" position from which the position of the throttle blade is determined in order to determine the injection demands of the engine. The method herein is for accurately locating an actuating lever (10) to the moveable contact of the potentiometer (12) so that at the home position, the signal generated by the potentiometer is a known value. In addition, the potentiometer only needs to be adjusted on the throttle body once it is assembled thereto to account for throttle body tolerances, thereby satisfying rigid engine control requirements which require the positioning of the potentiometer to be accurately known.
