My Front 02 Sensor (the one on the cat) has no power, I've traced all the wires there is nothing broken or messed up that I can see, everything was still wrapped up tight, I'm showing OBD Codes P1166 and P1167. And when I look at the graph on the bidirectional scanner it's completely flat, 0.0v, sensor 2 is functioning. Also, I replaced both sensors as a first step when I started getting this code, and these two codes are the only codes present, the car is clear besides those.
