Usually this may point to a faulty sensor. Easiest way to check is put the ignition on (but don’t start the car). Place car into reverse then put your ear right next to each sensor. You’ll hear a slight crackle/static sound if each sensor is working ok.

I used this method to diagnose and fix an issue with mine. £25 for a replacement sensor of eBay and all good.
