I got a 93 eg si hatch and I just fixed the cluster lights in it ( bad dimmer switch ) Anyways Now every now and then my speedo will just go crazy , go from 40- 100mph out of no where, sometimes it even goes backwards , then it will just all of the sudden go back to the right speed. . Any ideas? Never had this issue before. Thanks

btw it is the stock eg si cluster

in my case the speedo circuitry took a **** on me and i had to replace the cluster to fix it. do you have cruise control by chance, and if so does it still work even when the speedo is reading incorrectly? just kinda have to find ways to narrow it down to either the cluster or the speed sensor itself.

no cruise control, car has a full gsr swap

did it just happen? was it working before u fix the light?

i think the cluster is messed up. try tapping it while it starts doing the thing, and if not, then the speed sensor.

Yes it was working fine before.

I did try tapping it, Didnt make a difference

speed sensor failure. jack it at the junk yard. from any single cam or dohc. just not h series.

Okay so Sohc will work on the gsr?

hondawhiz

yeah.

I had the same problem. Turned out the pin in the plug for the cluster was spreading open. Check the condition of your connector. One poor connection will cause the same symptoms. I too replaced my VSS and cluster before I noticed the damaged pin. I just cut and soldered a newer, cleaner plug onto the harness.

okay thanks man , ill check that first. Is there any way to just clean the connections ?

my speedometer is doing the same thing. i was told the replace the speed sensor as well and it did not fix the issue.

hondawhiz

cluster could be bad. common problem

I had the same issue I removed the VSS and clean the conectors that fix my problem.

okay guys , I tried tapping on the cluster a little harder today when it started acting up and it started working, so tapping does stop the problem for a little. . then it acts back up again

i have the same prob. on my ek. my rpm and speed dont work at all. its been like this for a while. everything else works and no engine check. could it be a cluster gone wrong?

hondawhiz

then its the cluster for sure.....

Love-MY-honda

ok sweet thanks for the affirm. on that.

In EKs its common for the cluster to wear out (Mine did, and all the junkyard cluster all have the speedo assembly missing from them!). But I have clusters from EGs with over 500XXXkms and they never skipped a beat. Never heard of dead cluster issues in EGs but anything is possible.

They do go bad periodically, I went through 3 before a I got a good one in my '93 Si.

its probably not the speed sensor. I had the same problem on my 97 coupe and it turned out that the fuse for the speedo/alternator was messed up and dieing. Sometimes my speedo would work other times it wouldnt, other times it would randomly jump around (sometimes when I was even sitting still). It turned out to be a fuse. And I think that fuse blew because my alternator regulator died aswell. So I think the alternator caused the whole problem, so check your alternator, and your speedo fuse before replacing the speed sensor.

'92 - '95 civics never really had any issues that way. '96 - '99 Civics ('00 models aren't supposed to be affected) had issues with the engine harness rubbing the bracket under the intake manifold and shorting out the signal wire for the VSS among other things usually blows the alternator fuse and the speedometer just flys all over the place, dash lights pulse etc.

also would a a/t cluster work on a m/t?

94EG8

Yes, it will of course have the PRNDL indicator though.
