It was just a few months after I bought my 99 Windstar that I had problems. It always seem to happen after it had rained and when I got to the dealer the problem went away. After numerous trips they seemed to finally resolve the problem.
I was told that they used some kind of marine sealant on the sensors. It would appear that when it rained or after I washed the van the sensors would short out. That seemed to work for about 2 years now the problem has returned. The sensors seem to work after a few days of no rain. I think the sealant has broken down.

The backup sensors are located in the rear bumper. The four circles on the bumper.
On page 191 of the 2001 Owners Manual, there's a reference to the backup alarm for fuse #10.I didn't find any other references in the chart (wish the manual was better written in this area)Backup sensors, and a whole bunch more systems are protected by fuse #10, in the interior fusebox.See "Related Questions" below for more, especially about fuse #10 that keeps blowing out.

One can purchase a backup sensor from a local electronics retailer or through online retailers such as Amazon. Other stores may also stock backup electronic sensors depending on the individual's location.
one of the backup sensors has dirt in it,or did you mount something on the back bumper?
You can find about why your backup generator system isn't working and read information to compare prices on the internet or go to your local shops and en quire about it there.
It makes noise, yes. I believe you have to be within 12 inches of an object.

I find the backup sensor, aka rear sensing system, to be very helpful when: # parallel parking, and # avoiding hitting people, cars and lawn mowers that sneak up behind me when backing out of the driveway.
Ron Hazelton made a great video about how to install a backup power generator correctly and what to check when it is not working properly. Here is the link: http://www.ronhazelton.com/projects/how_to_install_a_home_generator_for_emergency_power
