My Rpm work's but my mph dosent. when driving on the freeway, or going 50mph it jump's to 120-140. I have pull out the cluster and to check if all the wire's are plug in or loose and still dosent work. And i have check the wire that's plug into the tranny. Still dont work? anyone have any idea?.Do i need to buy another cluster? Or buy the whole gear thingy that plug's into the tranny?

 

If you have access to either another cluster or a VSS (the thingy that plugs into the tranny) try using it on your car. Someone correct me if i'm wrong, but I believe the VSS would throw a code if that was the case. Its probably just the Speedometer. What is your year/model? I have an extra EK DX cluster for parts.

 

ur right it would throw a cel i have tha same problem w my eh9 and my temp gauge doesnt work either how to fix that i i've change tha cluster out and everything else to get it to work

 

Yeah my mph and Temp. doesnt work. But i guess ill just get a new cluster to see how that work's out.

 

I have a 93 si with ls motor.

 

Yeah that's probably all it is. I had problems with my tach in my 99-00 si cluster and I replaced the tach assembly and voila! problem fixed.

 

Yeah just change over your speedo. I bought an EX cluster for my egg and the speedo didn't work, I used the original speedo from the dx cluster in the ex and haven't had a problem yet.
