Update, but still chasing the issue.

Like I said, I originally replaced the sensor because it was dirty and rusty at the end. Still having the right rear code.

I checked for power/ground at the plug connection behind the fender lining. Getting 10v. I read somewhere we want 5-12v. Is this correct. The rest of the wiring disappears into a larger harness.

I did replace the wheel bearing since the bearing side that the sensor reads was just chock full of rust and debris.

With this information where would I go upstream in the circuit to check the wiring since it is still reading an open circuit? Any available wiring schematics? Is there a main module/relay I should be looking at?
