Check engine & ps light codes

Check engine power steering light coming on when I go in floorboard Deepwater they stay on for about 10 seconds and go out doesn’t matter if I’m still in the water or not. The The dealer replaced the speed sensor and it still does it. I have but dialectic grease in all electrical connections and liquid black tape around wires for speed sensor. The codes are for the speed sensor. Anyone eles have this problem? Any ideas
