Every GM vehicle I have worked on the sensor is behind the grill in front of condensor/radiator,sometimes near center & sometimes near left side headlight assembly. It should have 2 wires going to it. When you unplug it readout inside vehicle should change. If it does you know wiring is ok!
Good luck .
