Speedo inop intermittantly

I have a 1992 Civic DX. Five speed trans. The speedo will work for awhile then drop to 0. It stays there for awhile then starts operating normally. I have Ford experience but not much Honda. I know that it is electronic not cable, I think I found the speed sensor on the tranny. Is it more likley the speed sensor or a cluster problem? How would you test the speed sensor for proper operation? Is it a hall effect sensor, potentiometer, or what? Thanks in advance for your help.

Definitly a speedo sensor problem. I replaced the tranny on my friends '91 Si and his speedo didn't work. All I did was tighten the sensor in some more and it worked fine. Check the wiring and tightness of the sensor, shouldn't be too hard to fix. Good luck.

Have you tried fixing this yet? I want to know what went wrong..

Not yet. I drove the other day and it was working for awhile. Then it stopped. I went to gas station and unplugged the connector on the trans speed sensor and plugged it back in. Drove again and it worked fine again. :screwy:

Yeah, they are pos's. Expensive pos's though :(
