If you want to see the VSS signal, the meter has to be set on AC Volts. However, the PCM is not interested in the actual voltage, but it is looking at the frequency of the AC signal, so what is really needed here is either an oscilloscope, or an AC voltmeter that also has a frequency counter function. Also keep in mind that the transmission output shaft has to be turning in order for the VSS to generate a signal.
The test procedure on Craby's post requires the use of a Tech I or II scanner, and a signal generator which costs as much as the car. So, you could unplug the VSS connector, probe back to PCM by connecting a DC voltmeter between the Yellow an Purple wires and look for 12 Volt with the ignition ON. The circuit uses isolated ground so connecting between the Yellow wire and chassis ground is not a valid test. If this looks OK, then probe back to the VSS on the yellow & purple wires using an Ohm meter and there should be a high resistance short. If the meter shows 0 OHM or infinity, the VSS is bad. Also make sure that the PCM is sending a pulsing signal to the speedometer. You will also need special equipment to see this signal (scope, freq meter, Tech tool, an AC voltmeter may show some voltage)

 

Can those tune your car?
I'm digging the moates link I take it one is better than the other

 

i have the moats setup. yes you can tune for the 93 using a blank memcal.

 

Evidently I've been doing some tests wrong like using chasis or battery for ground and leaving vss plugged in. Hell the 3 20 dollar vss I have bought all could be junk from the get go.
So thois weekend and perform those tests and report back to ya's
Thanks a bunch. Guy's. Talk later art

 

Well I did some more tests and got another new vss. Still no luck
I got 2.36v on the ac side and I ohmed the plug and it was 15.something


Is it possible the gear in the tailshaft does not work?
Any st.louis locals here

I guess on the bright side car starts no problem and no security issues lol

 

inside the rear housing on the tailshaft there is a clip that holds the gear in place. check to make sure its in place and doing its job.

 

The only thing I can make out is a hard metal surface with two grooves on it which I assume is the gear that the vss is supposed to read.
The ses light only comes on only on deceleration btw

I guess the only thing left is to have a shop. Scan it

 

yah the 6 speed is different so i dont see a way the gear could be slipping.

 

Weird huh? Why couldn't it be a cable lol

 

Ok I'm gonna jack up car and remove vss if I put car into gear I should see something turning correct. Waay too many close calls t
With the law lately

Is the tailshaft easy to take off nothing gonna fall out will it
