Looking at the FAQ I found the oxygen sensor wires in the engine compartment.
I pulled the rubber boot up over the single wire spade connection. The sensor connects to a green wire in the harness of the car.

I measured the voltage there and it was bouncing around. Max was around .79 volts. Minimum was around .1 volt.

I made a vacuum leak and the voltage dropped below.2 volts.

I also looked at fuse #4 and it seems good.
