These sensors are a bone of contention & a bloody irritation for sure, and they don't have a set life-time...
and I've had almost new ones fail because I was too aggressive with the power hose.
Get on your hands & knees & take a listen to each sensor - as you have probably done before...
All the sensors should "click"... some times one will be slightly quieter then the others, and I've found this one to be the single item to fail the whole system....
If you swap it out and it still doesn't work, you may have more than 1 failed part, but swap them around & out until it works.
Worse case scenario is that you have a spare sensor... which you will need any way one day.
