Faulty back up proximity sensor

[crupp]

Has anyone experienced there back up sensor staying on while in reverse? Just this morning everytime I put the car in reverse the display on my dash shows one line directly behind the car and thier is a constant notification sound??

Only once, and it stopped when I washed the car. The car was filthy and it must have been something stuck to, or on the sensor. I have had no problems since. I will say that the car has not been as dirty as it was that one time.

There has been alot of rain here in Atlanta and the leaves and pine needles have been falling in droves so that coulde be it and I've had to keep the car outside the last couple of nights while I wait for my garage door opener to be fixed. Maybe she's just mad about being left out in the cold!!

I noticed that today on my car also. It seems that if the sensors get dirty, snow, etc. it could set it off, you can always trun them off, untill the car is cleaned...

Problem solved just took a clean rag and wiped all the rear sensors and no problems. There was fair amount of wax build up on the center sensor, this may have caused my problem.

My front sensors have been acting up a bit. Sometimes it won't make the beeping sound and then it will got to straight "line" sounds when I'm really close. It shows up on the dash but doesn't beep.

Any suggestions? Has done this more than once.

Other posters are correct that most likely culprit is dirt etc., but in my case I had to have one sensor repaired under warranty.

Started with false positives, then entire system disabled (probably due to constant false positives).
