This can be caused by dirt build up in the air gap in one of the sensors. carefully clean around the sensors with a tooth brush and water
DO NOT JET WASH! If this does not work check the connections to the module found in the bottom LHD Side of the boot, sometimes the plug connections are affected by water/damp. I had the same problem - pulled the plug off - remade it and sprayed with silicon spray to keep away damp - and its been no trouble since. If non of this works you may have a faulty sensor or unit.
Hope this helps - good luck.

My ford focus zetec reverse sensor comes on when i turn on the ignition. It stays on constant while i am driveing not beeping just a constant drone

It sounds like one of the sensors mounted in your bumper is bad or you have something obstructing one of them, mud, snow, etc.

unplug them one at a time until the noise stops, that will be the defective one

Reversing beeper has constant beep

The easiest possibility is that the proximity sensor thinks something is constantly very close to your bumper. Assuming you don't have any weird stuff hanging off your car that could confuse it, the sensor is likely damaged.

Reversing sensors on my 05 Sportage beep constantly when in reverse. I have cleaned sensors but it still happens. What could it be

I am not sure what noise you have. it sounds like its either a reverse alarm which sounds when you are backing up. that's what it is supposed to do. If it is an alarm... it may be telling you that you have a reverse light out.

Reverse censors are on constantly when in reverse.

One of your rear sensors ( 4 of them located on the back bumper) has most likely failed or was damaged. Check the back sensors for any visual damage (they are about the size of a nickle) and panted to match the rear bumpers paint.

Good Luck!

Sensor beeping continously in reverse

Try to clean rear parking sensors. Check also electric cables and connections, clean if necessary. Commons faults are sensors out of order. If one or more sensors faults you hear only a continous constant noise when you put in "R" gear. You need a VAS, VAG-COM, Bosch KTS, ... diagnosis scantool. The factory parking system will be scaned from errors with this instrument, and you will find exactly which sensors are out of order (for example: rear left center sensor, rear right side sensor break off, short to ground or short to plus).

My 2003 Jaguar S-Type has a faulty Reverse Park Control system. When shifting into Reverse gear, a constant tone sounds until the gear is shifted into a forward gear or neutral. What are the usual causes...

This is a sensor fault. The easiest way to locate wich sensor is faulty is to get up close to the sensors when the car is in reverse gear (engine off) with the ignition on and put your thumb nail on the sensor face as this will amplify the ticking noise that can be heard from the sensors. No tick indicates a sensor fault.

To disconnect the system will just give you the same problem with the constant tone unless you disconnect the park aid module wich is located in the boot of the vehicle on the left hand side behind the carpet trim. Beware that the handbrake module is there so ensure that you are looking at the right module (it will say on it)

Sensors are not expensive unless you need to have them painted to body coulor as they come in black. Easy push in/out fitment from the behind the bumper. Corner sensors can be replaced with the bumper in situ but centre sensors require the bumper to be removed.

Hope that helps
