When tried to start, engine info light on and code CCU 100.04 (low oil pressure). When put in gear, power shifter will not get out of neutral (maybe a permissive?)

oil pressure switch has one lead. When taken off switch and grounded, the low oil code goes away but power shifter still won’t get out of neutral.
Any ideas? Maybe a relay ?
