Seems as if you'll need a new VSS (Vehicle Speed Sensor) .. do a search, you'll find the topics.

They can be had inexpensively from eBay ..

It's in the engine bay .. above (on) the tranny ..
but like '93CB7Ex said .. check the connections first .. it may be faulty .. it happens ..
But more then likely, it'll need to be replaced ..

Yes. Although I found your grammar a little confusing to decipher, I think I get it

There are two. Your interest is with the countershaft speed sensor.

It is on the RIGHT hand side of the transmission. You'll see it sitting there near the rear trans. mount. Remove it's 6mm bolts, remove the sensor itself, and replace. Remember to also replace the o-ring before re-installing the new sensor. Make sure it seats well and proper too.

no such thing as a countershaft speed sensor on a cb7. the VSS gear rides on the differential.

youll see the sensor if you look directly below the throttle body.

alot of times the connector itself is faulty. I would take the plug off and inspect the terminals for any corrosion or problems with the connection first.
