Sensors use a 5v reference to be able to read it. It might be a break in the cable and it either kills or shorts the 5v. So yes it is possible that the share a power or earth and thatbth one can affect the other.

I have never seem a route sketch for a harnass in all my life. So not sure where you will find that other than the factory. It usually involves a couple of hours of hunting with a multimeter to the fuse box.
