I have a 1991 Toyota 4Runner 6 cylinder 5speed manual that uses a lot of power steering fluid "ATF fluid for this Toyota" but I can't find a leak anywhere. Where is the fluid going and is it possible for the fluid to get into the engine?

An air control valve is used to increase idle speed when heavy loads exists on power steering pump. Pickup uses standard or electronic power steering. On electronic power steering, vehicle speed is detected by speed sensor in instrument cluster. Fluid pressure is regulated according to vehicle speed by power steering Electronic Control Unit (ECU). On Pickup and 4Runner with anti-lock brakes, power steering pump delivers fluid through actuator for brake system. Special bleeding procedure must be used on this system.
