Looking for advice on replacing the Vehicle Speed Sensor (VSS) on my 99
Taurus. Can anyone enlighten me? The local Ford dealer wants an arm and
a leg to diagnose and
replace the VSS. Have researched and am pretty sure the problem is with
the VSS or the wiring. (speedometer at zero, no shift until 4000 rpm,
rough shifting, "OD Off "light flashing, "service engine soon" light ).
Unfortunately, my research on the newsgroup also indicates that, on a
99 Taurus with a 24V DOHC engine, the VSS and connector are difficult
to reach and remove. I've located it on my Taurus and see why.
Does anyone have any advice on removing the VSS. I've heard that it
could be seized into the transmission housing, and that the rear of the
subframe and exhaust system might have to be lowered to get it out.
1. Would removing the intake manifold, as when changing the rear plugs,
provide access from the top of the engine?
2. What sort of connector is used for the wiring, just a "push on", or
threaded? How many pins?
3. If the subframe has to be lowered, are there any suggestions how a
home mechanic can accomplish?
4. If the subframe has to be lowered, will the exhaust system have to
Any help would be appreciated.
