Hey everyone, so I've come across the irratic speedo problem on my 99 si with 127k. Wen I turn the key on,it will either jus bump up n down real fast or bump up to 20 mph and stay their, so I unplugged the vss and same problem still exists,I haven't had time to go more in depth but I do notice my idle is higher wen the vss is plugged in but that happens wen the speedo goes in and out of working.

 

Post the CEL codes.

Is fuse 15 blown?

 

Thanks for the reply bro, no fuses blown from wat I see it I'll check wen I get up, wats fuse 15? And theirs no cel either :'(

 

Does the CEL work? It should come on for 2-3 seconds when you first turn the key to ON(II).

 

Hey everyone, I'm searching to buy a vss for my 99 em1 and was wondering wat or if any other model civics(sohc,sohc,dnt matter) vss would bolt/work iny b16?

 

Bumpy

 

Yes, cel cycles as should. I pulled the ecu and looked under the cover, everything looks good per say.

 

*per se

 

bad speedo or cluster. common symptoms.

 

Usually when that happens to me its because there is water in the speedo plug.
My car used to have a coolant leak that would sometimes spray there.

Check your speedo and see if you find any water in the plug.
I blew mine out with a can of air and left it off during a dry day and it didn't happen again.

 

No, but one from a '94 - '01 Integra will work.

 

Yes! 100% yes. You can use one from a sohc motor (must be from a manual and must be a hydro tranny). All you have to do is remove the small cotter pin from each VSS, and then install your EM1 gear from end of vss onto the SOHC one! Reinstall cotter pin, install into your vehicle, and hit the road!

I have done this 156734 bajillion times, so trust me... it works!

Good luck to ya, hope you enjoy your new working vss!

I live in az so its hard to say their is a water leak, I've pulled the cluster several times and connectors were bone dry. Anyone have a parts cluster they wanna sell

 

Josh, mahalos (thank you) for the info, I felt like it would work cuz they look similar but I'll do that :-) thanks again brotha :-)

 

This is gonna sound weird, but that happens to my 94 Honda when my battery is old and not giving enough volts/amps when starting the car.

How old is your battery?
If you want you can just go to a shop and get the battery tested.

Just wanted to give my 1 cents of input as this exact problem happened to me a few times.Use it, don't use it.It's your choice.

 

Np man! Swap the gear then dissapear happen to have any pics of your em1? I just picked up a bone stock 2000 EBP EM1 last week!

 

I figured this was what needed to be done just wasn't sure. Good to know.

 

Tap on the speedo window, while moving.
Mine acts stupid, or gets stuck at a certain speed.
I tap on the window and it goes to where it should be.

Thinking its a bad connection in the dash somewhere.

 

Check all grounds. I had the same issue when i had a loose ground to the body. However all of my gauges were affected when my ground was loose.

 

Its not the cluster connectors, its the connector to the VSS. There is a coolant line above it (throttle body) that can easily drip on it.

I've seen it many times.

 

 

I have no coolant leaks and I've inspected the harness above the sensor and seems fine. Battery is a couple years old but I did take the cluster aprt ish, popped the needle off, hooked it up and turned the key on and I could see the stem of the needle move so I figured put the needle where it should it would stay at the bottom but no matter wat I did, it went back to the same spot so I feel the speedo cluster itself is no good

 

It could be that the cluster itself went bad, I've seen it happen before. Just not in any vehicle I have owned.
