THIS IS A SUGGESTION TO BE FOUND FOR SOMEONE WITH SIMILAR PROBLEM. Sympton........ speedometer goes nuts or off and on odometer does at same time. i have a 2000. 96-00 same gauge cluster i am told. i replaced the speedometer sensor to no avail then a new battery also a waste. then checked the wiring not a problem. then off to a junkyard for a actual speedometer part or cluster as they call them. by the way a cluster at a junkyard cost me like 35 bucks and the shipping on one from the net is like 15 bucks. I had a dealer check that speedometer sensor for free so do that before you replace it. It by the way can be changed in like 10 minutes. The speedometer cluster has 6 screws and takes about 5 minutes to change. i changed mine and all was well. but as i did not like the new miles racked up on the replacement. i had taken the face off the cluster earlier just push clips. take out the four screws on the back of the speedometer part and you will find a 3 inch size computer board that plugs in easily. I change the new one from the junkyard to the old one with the correct miles and whala all is great!!!!! now i have an extra tach and bulbs and such for later which was tonight i found out. personally i'd go here first.

 

You swapped boards and the miles changed back to what you had before?

I've been busy trying to figure out how to control the stepper motor that runs the odo so I can get it to run backwards to adjust my miles on my new cluster. No luck on that yet.

 

no i took the old one apart and put the card from the junkyard higher odometer working one into the one i started with giving me the correct and now working speedometer.

 

ya i did the same thing with my 94 LUCKELY i found a cluster on ebay withonly 1K miles more that what mine had. so i just swaped out the speedo part and it works great! same thing goes for 92-95civics. same with the other gauges as well if they stop working.... either tach, fuel, temp gauges depending what model cluster you have the pieces will fit. cause you cannt replace a DX cluster side gauges with a EX cause the rear electronics dont match up
