Check VSS(vehicle speed sensor).Erratic communicating signals back and forth w/ the PCM can cause improper shift points,plus the inoperable speedometer points at that direction.
Most likely speedometer cable
I have the same problem hope someone tells us what to do Mel
You would fix it by replacing the instrument cluster. The speedometer itself may not be faulty, it is more likely to be a problem with the speed sensor.
not sure,,,,,,same problem here not sure if it ia a cable or eletronic. May be a relay or something. If I find out I will post

There is no fuse just for the speedometer. If the speedometer is not working, you may have a problem in the dash gauges cluster, or a vehicle speed sensor problem.
Cruise will NOT work if the speedometer has a problem
If a 1992 Honda Civic's speedometer is erratic, the problem could be the speedometer cable. It could also be the speedometer sensor malfunctioning. Check both components carefully.
Have vehicle scanned to determine the problem
There might be a problem with the cable.
check the wiring to the speedometer. Check the sending unit as well. If the problem is internal then the speedometer will have to be replaced.
Cable could be loose.
