SYSTEM FOR CONTROLLING AN ELECTRONIC THROTTLE BODY

A system for controlling an electronic throttle body includes an engine speed setting device having a first terminal coupled to a source for a reference voltage, a second terminal coupled to a first end of a conductor and means for varying a level of resistance between the first and second terminals. The level of resistance is indicative of a desired engine speed. The second terminal outputs an analog engine speed signal indicative of the desired engine speed on the conductor. An electronic control module includes an engine speed signal processing circuit including a resistor coupled between a node located between the first and second ends of the conductor and one of a voltage supply and a voltage return. A controller coupled to the second end of the conductor is configured to generate a control signal for the electronic throttle body responsive to the engine speed signal.
