'94 YJ Speed Sensor
I called my dealer today, and found that the '94 YJ does not have a speedo
cable. It has a speed sensor, which he says might be the reason the
speedometer reads erratically, bounces around, and sometimes does not read
at all.
Anybody ever replace the speed sensor on a '94YJ? Any hints or ideas as to
where it is and if it is easy or hard to replace?

Re: '94 YJ Speed Sensor
If the sensor was bad, it would normally not work period. Most
electronics up and quit, they don't give fits first.
You are now describing a dirty connection on the plug for the speed
sensor. A contact cleaner spray does wonders for these computer signal
plugs and sockets. WD40 will work for this but a real contact cleaner
is better. I also use dielectric grease on the rubber skirt seal the
plugs have to help keep them clean.
I don't know for sure, but I think I remember someone saying it was down
on the side of the t-case.

Re: '94 YJ Speed Sensor
I had a bad VSS (Vehicle Speed Sensor) on my 91 YJ and my speedometer still
worked fine. For me, when I would push in the clutch when coming to a stop,
the engine rpm's would drop way down to where the engine would almost die
and sometimes the vehicle would shudder and then usually the rpm's would go
back to normal just before it died. It is located on the tcase, I belive
it was where the speedo cable plugs in.

Re: '94 YJ Speed Sensor
The speed sensor plugs mechanically into the transfer case near the output
shaft. It has an electrical connector that plugs into the nearby wire loom.
Your speedo is more likely filled with dirt and grime and is sticking, or
the ground to the dashboard electronics is intermittant.
