Speedometer: '95 Taurus

The speedometer on my wife's '95 Taurus (automatic, 3.0 L v-6) went crazy on
the trip to Boston this Thanksgiving. I noticed that I was going above the
speed limit and was being passed by everyone. I plugged in the GPS and found
that the speedometer was reading about 10 mph fast at highway speeds. Also,
above 65, it would occasionally drift up 10 mph then back, accompanied by a
grinding noise.

It sounded to me like the speedometer cable had broken and was occasionally
catching the loose ends. This happened to a car of mine about 30 years ago.

The question is, does a '95 Taurus have a speedometer cable or is it all
electronic? If it's a cable, I can replace it, but if it's an electronic
problem, I'll probably have to take it into the shop.

Thanks for any help you can give,

Paul

It's electronic. If I were to guess, I'd say that you have a Vehicle speed
sensor problem. However, it's possible that you have an intermittent ground
in your instrument panel.

The speedometer on a '95 Taurus is all electronic. You would have to
take the vehicle to a dealer or a garage and have them repair it.

On the older Taurus, the digital electronics dashes used the VSS for the
speed sensor and the mechanical dashes with a needle used the old
mechanical spedo cable. In any case, changing the VSS is not a bad idea.
Usually, the trannie with shift strange or the cruise control will pop off
unexpectedly if the VSS is going bad (or VSS wiring).

The VSS is between the motor and firewall on the top of the transmission. The
spedo cable plugs into it. The ones with a electronic dash will have a short
stub spedo cable that does not go into the dash. The mechanical spedo units will
have a long spedo cable that penetrates the firewall.

I know on my 93, it still has a mechanical spedo with a cable.

The analog gauges on the 1995 Taurus are mechanical, and actuated by a
speedometer. Only the Digital cluster was electronically controlled by the
VSS in 1995. In 1996, analog gauges were all electronic.

A bad cable tends to cause a lower than actual reading, rather than an
higher than actual reading. If the noise is coming from behind the
dashboard, there's a fair chance that your speedometer itself may be on it's
way out.

Meant to say actuated by a speedometer cable. My bad.
