The fact the rear left sensor voltage is reading as zero would point in the direction of wiring. Can you confirm the voltage reading at the sensor itself? You should see ~5v at the sensor input - if you don't then the supply wiring is suspect. You should see a non-zero value at the sensor output, and see it vary as you move the sensor through its range of motion. If not, then it's the sensor or sensor wiring itself. If you do see voltage at the sensor output then that would point to the return wiring being suspect.
