Popped her into reverse this morning and got a beep beep beep beeeeeep!!...I did the old listening to each sensor and they were all ticking nicely....could it be a loose connection somewhere rather than a faulty sensor?
Faulty wiring is always a possibility with anything electrical. Besides loose, could be wet, dirty, corroded, etc. Or the insulation could have been damaged by improper routing, road debris, poor workmanship, rodents, etc.
