Borrow or buy an engine code scanner to find out what code is stored. The fact that the "check engine light" is on is a huge clue. That may give you all of the information that you need to figure out what's wrong.
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.
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
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 both odometer and speedometer are not working I would blame the vehicle speed sensor. If just the odometer isn't working the gauge cluster assembly needs to be replaced with a reconditioned one.
maybe your speed sensor is bad you will get a check engine light on the dashboard too.
If the speedometer and odometer are both not working, I would blame the speed sensor. If only the speedometer does not work and the odometer does work, the cluster is bad.
Does your odometer work? If the speed sensor goes faulty both speedometer and odometer stop working.
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).
There is no such thing as an "odometer sensor." There is a vehicle speed sensor that is located on the output shaft housing of the transmission. That sends info to the speedometer. From there, the speedometer and the odometer are both operated internally, so if your speedo is working, but the odometer isn't, you have a problem inside the speedo head assembly.
1. operates the speedometer and odometer. 2. provides vehicle speed information to the engine and transmission controllers.
Nothing
If the speedometer is not working but the odometer is, I would suspect the dash cluster is at fault. If both speedometer and odometer are not working I would suspect the speed sensor on the transmission is at fault.
