1998 Chevy Tahoe V8 Four Wheel Drive Automatic

I coded my Tahoe and came up with a P0405. I checked and cleaned the ground. It made no difference. Do I need to change the valve or is there something else todo for a low circuit?

Chances are it needs replaced. Make sure there are no breaks in the wiring.
