Vehicle Speed Sensor / Speedometer Readings

When testing the incoming voltage from the computer at the Vehicle Speed Sensor do we check for 5.0 volts in AC or DC? I have read the speed sensor is actually an AC voltage generator so this is why I question. I did replace the sensor because I was under the car but when I probed with my meter (meter set to DC) the pink/orange to grey/black wire in the harness that plugs into the sensor I only was getting 1.75 volts.

I did test the old and new sensors on the bench against DC on my volt meter and seen it was generating power when turning it also.

Basically with KOEO my speedometer raises to 15 mph so I am trying to diagnose this problem. What supplies the speed to the cluster? is tied to the computers VSS+/VSS- wires?

Thanks for any help killing the last of my gremlins with this car.

So do you know what the voltage going to that vss sensor from the computers vss+ should be I believe its pin 3 or 6 on the ECU. Or does the ECU not supply an voltage to it?
