VSS Data

I'm looking for information about the VSS used in a second-generation Taurus. I've seen a lot of posts that say they're 8 pulses per rev and 8000 pulses per mile, but I'm wondering where I can see the specs myself. Is there a document or a book that has this sort of data?

Unfortunately I don't have a reference (the service manuals don't mention anything), but I believe 8 cycles per output rev is correct. The VSS is a VRS (variable reluctance sensor), so it generates a sine wave output that increases in frequency and amplitude with speed.

The total number of pulses per mile is going to depend on the current tire size. The stock tire size for your car is P205/65R15, which equates to about 815 revs per mile. If you multiply that would be about 6520 pulses per mile.

Every Ford VSS I have dealt with since the early 80s when most Fords went to EFI have been 8 pulses per revolution. I have used a signal generator based on this 8 ppr value to check and calibrate several Ford electrically driven speedometers while they were out of the cars.
