Question about Honda Cars & Trucks
I believe that in '91 or '92 Honda switched from an analog (cable-driven) speedometer to a digital (sending unit/electronic head) version. Likely problem is the sending unit attached to the transmission. Try this website for a replacement and an image of the sending unit: http://www.carpartsdiscount.com/auto/parts/92/honda/civic/switches_sensors_and_senders/speedometer_impulse_sender.html?3593=89758

SOURCE: 1997 Honda Civic EX power loss
start with the easy stuff. check the plugs. make sure they are not wet with oil leaking from the spark plug stem seals located on the rocker cover. Check your air filter to make sure its clean. Now for the slightly harder stuff. The spark plug wires should be changed every 80k or so. My suspect the reason for the power loss is most likely a clogged cat convert in the exhaust system. check your exhaust flow. Way to do that is to check the temp. of the exhaust before the cat and the temp. after the cat. If the Cat is plugged the temp before the catalytic converter will be abnormally higher than after the cat.
BUT if you are experiencing misfire of engine. I would go straight to replacing spark plugs and wires. Distributor cap and rotor.
Also check the charging system. make sure the alternator is charging the battery at above 13Volts. With all components on. ( radio/lights/highbeam/AC). Use a voltmeter and check at the battery positive and negative. if its not charging above 13 V replace the alternator.

Sounds like either your speedometer cable, your nylon gear on the side of the tranny where the cable ties in, or the odometer itself is shot. One of those three will set you straight. If you are able, remove the cluster, take the cable off the back, and pull it out of the sheath. You will see if its broken or not from there. If not, slide it back into the sheath, then you have to find out where the sheath meets the tranny, and pull it off of there. Then, you can get someone else to watch the speedo as you turn the cable from the bottom. If it works, great, if not, then its your cluster/odometer/speedo. If it does work, the small gear in the transmission is shot.

There was a recent class action law suit settled with GM for this exact problem. You can google gm speedometer lawsuit and get lots of information. Unforutunately for most people I think the warranty was limited to 7 years and 70,000 miles. Which isn't a lot of miles for most people.
If you car isn't covered by the warranty there is a way to "reset" the speedometer.
You can turn the ignition slowly like you are going to start the engine. There is a very small "dead" space where you will see your guage lights go off.
What you want to do is cycle the ignition switch from off to that dead space. Each time you do it your stuck speedometer will move towards zero about 10 mph. So if its stuck on 40 you will have to cycle it at least 4 times.
At first you will probably actually hit the ignition and the engine will try to start.....just release it and try it again.
I know this because I have a 04 avalanche with 80,0000 miles and it has this problem about twice a month.

Replace the speed sensor located on the transmission this sends the signal to the speedometer, you may want to check the plug and its terminals to be sure the terminals in the plug are not corroded if they are clean the terminals with electrical contact cleaner then drive the care see if cleaning the plug fixed it if not replace the speed sensor.

There have been several issues with the instrument clusters in the Voyagers and Caravans. The circuit board can have cold solders at the plug connection causing an intermittent failure of the instruments. The fix is to remove the trim under the dash, around the steering wheel and in front of the cluster. This can be done with just a phillips screwdriver and some patience. Once this is out of the way there are 4 screws that hold in the cluster. Remove the cluster, and with a low temp solder gun, heat the solder points where the plug connects until they are liquid and reset themselves. Reassemble the cluster and check them before you put the dash assembly back together.
