Parking sensors?

Had two parking sensors short out, unhooked them, now the system doesn't work.   Do all the sensors have to be hooked up I'm order for the rest to work.   2015 gmc sierra

They all have to work.  The computer disabled the system because it is not getting inputs from both sensors.

Probably so, Have you thought of learning to park without the help of technology?
