Hmmm seen as the sensors aren't all directly related id say you've got grounding or water ingress problems mate.

Check your fuse box for water. Pull each multiplug apart and check for water or corrosion.

Check the wires of the individual sensors just to be sure they not trapped anywhere or damaged.I you have a DMM do a continuity check.

After that I'd work around the earth points in the car and clean them, the earth terminals on the cables and the securing nuts, bolts back to bare metal before re-building and cover in copper grease to protect.

Good luck
