Back up sensor
I just purchased my Ford F 250 superduty 2002 with a 5.4 triton V8.
My back up sensor system worked for one day. Today, I noticed the light that indicated the back off sensing system is off ...was illuminated indicating the system was off. I tried to turn in on and it would not turn on??? When I start my truck, I hear a small churp. When the truck is in drive, I can turn the system on, but as soon as I put my truck in reverse, the light illuminates and indicats the system is off.
What gives?
I checked the fuses under the dash and all are good.
I purchased a Haynes repair manual, and they are pretty much useless on these issues.
Any help would be greatly appriciated!

Wow. Well, you could probably pick up a used working sensor at a salvage yard cheaper or if you can find a buddy with the same setup, borrow one of theirs just to test.

OK, Now it does not work????
I"m going to go get some electrical contact cleaner and try cleaning it again. After I hit it with electrical contact cleaner, i'm going to clean the connections with compressed air.

I don't think there have been any changes to the sensors themselves if you're just looking for one to use as a tester. I believe the appearance changed on the '08+ trucks so if you got one from an earlier truck to test with and found a bad sensor you needed to replace, you'd need to get one for that model year if you're concerned with the looks matching and the correct fitment. I believe the sensors in the '08 trucks fit a little differently as the bumper contour changed.

well his truck has been there for it leaking antifreeze all over the place, and just a couple of weeks ago they finally figured out it was the head gasket. after two years of the same issue four egr coolers, and whatever goes along with it. O and the truck only has 40,000 miles on it
