1999 Mercury Villager speedometer sensor

Here is what I was able to find.

Disconnect the negative battery cable.
Raise and safely support the front of the vehicle securely on jackstands.
Disconnect the VSS electrical connector.
Remove the VSS hold-down bracket bolt and remove the bracket.
Remove the VSS from the vehicle.
The installation is the reverse of removal. When installing the VSS hold-down bracket, tighten the bolt to 44-61 inch lbs. (5-7 Nm).


Let me know if it helps.
