You have a speedometer gauge, a distance sensor (VSS), an adapter and pinion in the tranny, and the connecting wiring. I don't have a wiring diagram of it to check and be sure but it may also go thru the computer.
I would first check the fuse it is on.
I would then check the wiring and connections to make sure they are OK.
Then read the pins of the sensor. There should be continuity. If it is open it is bad.
If that doesn't find it, a good wiring diagram should tell you what the voltage should be on the associated pin on the computer.
