backup sensors staying on in reverse

[Cobra3824]

My 2004 F350 lariat came with backup sensors when I bought it a year and a half ago. Yesterday I was out plowing for like 6hrs and had no problem with them. After plowing went to my real job where the truck sat for 10hrs. Hopped in it and now in reverse the sensors will constantly beep. Tried cleaning them thinking something might be stuck on them and they still do it. Would you guys have any Idea on what to look for or have experience with them staying on? Any help would be good. Annoying having to push the button every time. Plus the girl drives it once and a while and wouldn't mind having them work haha thanks in advance.

Mine are also doing that if truck stay he do not like eny thin ice ore frozen fog on them.

yeah well now its doing on and off. Most of the time it'll stay at a constant beep while other times after driving it'll work like its supposed to. Like I said before I cleaned them to get everything off and it still does it. Any more ideas?

If by chance yer tailgate is down, that will cause this.

Nah tailgate is up and everything. Doesn't seem like a loose wire because I jiggled them around and it still did it. Could it be that one of the sensors is getting bad and causing it?
