The sensor output is an AC voltage of around 1 volt increasing to about 3 volts as speed increases. Of course the frequency increases as well. It is easy to measure at the cluster connection and drive the car around the block. You could also measure by jacking up a wheel and spinning it, I believe the drive shaft must turn to get an output.

Never heard of the sensor bypass. I doubt you could make/break the connection fast enough to see a result at the speedo.
