Rear sensor orientation and sensitivity

[Steve o]

I replaced my rear bumper with the ARB Zenith metal bumper. I relocated the rear sensors in the proper order from left to right. However, their sensitivity seems much less now. With the old OBX plastic bumper, the sensors would detect cross traffic 12-20ft away. Now its like 2ft.
Do I need to turn my sensors? I'm 100% confident that they are in the same order placement as original.

CTA sensors - It certainly is possible that their orientation needs adjusting. I'd normally suggest looking at the harness, but you indicate they are working just not as sensitive as they used to.
