Reversing sensors sounds continuous-any suggestions?

[Dave Smith]

When I put my 75 in reverse the sensor has started to sound continuously.......not every time but problem is getting worse. Is it electrical or mechanical ? Is it something I (complete mechanical dunce:shrug:) can fix ? Should I take it to a garage or auto-electrician ?
Thanks

See if they are working first, put you ear to the sensor while in rev and listen for a ticking sound from each sensor individualy.....

They may be dirty and need a bit of a clean

As you can see the wires joint carrodes and the sensor fails

1st time back to computer for a few days-but thanks for suggestions. I will 'listen' outside today.
Sometimes they work fine and other times the sound is just continuous (from inside the car).
