Well, that MAY fix the problem BB. Here's the deal with around that year car. The VSS signal is actually sent to the ABS module where it is distributed to the rest of the car. So if you are having multiple problems, then your problem can be from the source or the ABS module itself. I found out something very interesting one day. I had one with an ABS light on. Everything else on the car using a VSS signal was just fine. When I pulled the ABS codes, I had TWO sensors that were totally dead. My scan tool would actually read each individual sensor. I then checked each sensor with my meter and confirmed the only sensor I had working was the LF. Yet, my VSS signal was perfect. Speedo, cruise, trans, all of it worked fine. After reading the manual, it appears the ABS module will take any of the three sensors available and use it for the VSS signal. Makes sense. So if the 2000 is that way, then some work needs to be done to find where the signal is being degraded. It's possible it could even be the ABS module. This needs some "detective" work...
Now, just to throw a wrench in the pile, somewhere around 2000 or 2001, Ford changed the way the VSS is processed and I believe it's all handled by the PCM. That design might very well only use the rear sensor.
