Abstract
A power steering load compensation system for an internal combustion engine which employs a pressure sensor to monitor the output pressure of the power steering pump. The pressure sensor provides an input signal to an engine controller, and the engine controller generates an automatic idle speed output signal for controlling the idle speed motor of the engine throttle body. By varying the air flow through the throttle body in accordance with output pressure of the power steering pump, which varies with the pump load placed upon the engine, dips and surges in engine revolutions per minute (RPM) at idle and low speeds may be substantially reduced.
