Backup sensor inopperable

Recently bought an 00 7.3 excursion.

The switch for the backup sensor is constantly highlighted "off". Even tried in reverse, with no change. Where should I start in trying to find out what's causing the problem?

Yep, the dealer can tell you which one is bad. (Well they did on my '11) plugged the new $110 (!!!!) sensor in, and it worked instantly.

yeah mines the same way, someone told me that when one goes bad none of them work....so you have to figure out which one it is...."BIG" how much did it cost for the dealer to run the test for you?

They told me which one was bad when I brought it I to them before I bought the truck. I was having them do the whole checklist / 80 pt inspection.

If you know someone with an AE it'll tell you which sensor is bad.
