Very sorry but I can't find any reference to that steering system other than that it exists. Everything I've seen uses a belt-driven pump, and that's all I can find parts listings for except right on the Mazda web site. The best I can suggest is since lots of water was involved, check the electrical connectors for signs of corrosion. That can become conductive when it gets wet. That most often affects low-current signal circuits, not the high-current pump circuit.
Don't overlook moisture getting into the fuse box. Safety systems like air bags, anti-lock brakes, and electronic steering systems all require computer modules, and all will have a minimum of two fused power supply circuits. One is needed to run the warning lights when there's a problem with the other one. Corrosion on a fuse's terminals can stop a circuit from working while the other circuit will run the warning light.
