I suggest you try one of those instant download manuals.
My brother ( a mechanic) buys when he can't fix some technical issue with the manual at www.reliable-store.com . A lot of mechanics actually do this. Website is very good for this. Must try it !!

fan relay or fuse

if the speedometer works, but the odometer doesnt, then the problem is the speedometer cluster.

Your oxygen sensor needs to be replaced.
The one behind (rear of )the converter on the exhaust system.
The code reads......P0136 (o2 sensor malfunction bank1 sensor 2)

sounds like vehicle speed sensor i had to replace instrument cluster on my civic

There is no cable on the 93 Prizms.  The problem is one of two things, either the "vehicle speed sensor" or the instrument cluster itself.   I also have a 93, and the speedometer started acting up a while ago. Sometimes it would register 0 then it would spike up to 70 and stay there at highway speeds then back to 0 upon slowing.  I replaced both items from the junk yard.  The speed sensor at an auto parts store will run about $160, and a new cluster will cost A LOT more at the dealer! I first replaced the speed sensor with no luck ($5.00 at the junkyard) the same thing happened 0 or 70.   I replaced the cluster today ($13.99 at the junkyard).  That was it! Problem solved.  The cluster is EASY to replace, remove the 2 screws from the trim piece and remove trim.  Next, remove the 4 screws that hold the cluster in place; 2 at the very top (don't remove the ones just above the cover glass) and two at the bottom.  Pull one side of the cluster out; there are 3 plugs; squeeze the center of the plugs to release the clip and wiggle them free.  Connect the replacement cluster, but before screwing it in, do a check to make sure all the panel lights work.  I had a few that were burned out, so I used the old cluster lights to replace them.   I would try replacing the cluster first.  Good luck!

just unbolt it and replace it, that easy

On my 96 the PSOM module went bad. That is located on the back of the instrument cluster. Mine is analog not digital. What was happening was that the PSOM (Programable Speedometer Odometer Module) would mess up and the speedometer would jump all over the place. The tranmission is electronic and the computer would adjust and shift depending on the speed reported by the speedometer. The van would **** and shake. At slower speeds it was much better. I changed the speed sensor first without success. Changed the instument cluster and all was well.
