Parking sensor going insane

[53helofe]

I think one of my parking sensors is going insane. Sometimes the right rear sensor starts screaming at me even if there is nothing near the rear of the car. The reason I say it is going insane is because it does not do it all the time

Anyone else had any trouble with their parking sensors going crazy for no apparent reason?

The only time mine was chirping - and it should not have been was when the bumper was covered by snow and ice. Perhaps yours has something on it?

I have not looked at it but I will, no snow or ice in my area. It did it before and seemed to stop, perhaps I washed some road grime off. I did just take a two day road trip so there could be some junk on it, I will check. Good suggestion!
