A target speed module determines a target speed of an engine coolant pump of the vehicle. A speed adjustment module determines a speed adjustment based on a position of a valve, wherein a backpressure of the engine coolant pump changes when the position of the valve changes. An adjusted target speed module determines an adjusted target speed for the engine coolant pump based on the target speed and the speed adjustment. A speed control module controls a speed of the engine coolant pump based on the adjusted target speed.
