The cable that controls the speedometer needs to be replaced more than likely. That is what had to be done to a Dodge Stealth's speedometer to work properly. ==New Answer == Actually - there is no speedometer/odometer cable on a 1993 Honda. The system is all-electrical. So it has to be either a bad wiring harness/plug connector, OR a bad speedometer head (unlikely).
If the speedometer works, but the odometer is not working, there could be a fuse blown if the odometer is digital. If the odometer is not digital, then a gear is broken in the speedometer cable. It should be replaced.
you need to change the speedometer cause if your odometer is counting then speedometer should be working too. make sure your speed gear its working its in the side of the transmission The odometer and speedometer read off of the same signal. If one works, the signal is ok and the other gauge is bad.
If the speedo works, but the odometer doesn't . The cluster needs replaced.
The odometer is broken and needs replaced.
Most of the time, the speedometer cable breaks, and you replace it. The best way to find out, is to unscrew it from the transmission, and see if you can pull the cable out from the casing. If it checks out to be good, then it will be the drive gear inside the transmission, or the speedometer itself.
If the odometer stopped working and the speedometer and cruise control still work, you have a bad odometer. It is part of the speedometer assembly so the whole thing will have to be replaced.
Speedometer is ran by electronic sensor on rear end. Odometer is ran from speedometer. If both don't work problem is sensor. If speedometer works sensor is okay. If speedometer works and odometer does not problem is in mechanical parts (gears) of of odometer and has to be replaced. Can get used from eBay (search for speedometer or odometer, is one unit) or take to dealer.
If it's an analog speedometer, first check the condition of the speedometer cable. It may need to be replaced.
Should read "...speedometer and odometer don't work..."
When those things on my 92 B250 did not work, I replaced the speed sensor located on the transmission tailshaft and that fixed the problems. Hope that helped! Mark When the speedometer and odometer did not work in my 1990 B250, I had to replace the speed sensor, instrument cluster (speedometer) and replace a tiny gear (odometer) in order to get them working properly
Your speedometer, odometer, and cruise control quits working; That's all. It happened to me when I replaced the transmission on my Altima and the two wires came out of the connector.
The speedometer is wired to a VSS. If it has failed then the unit will need to be replaced. Odometer and trip meter are wired into the same fuse and should be checked. If the fuse is blown the odometers will not work.
