i have a 90 crx with a 95 ls cluster and i used a vss from a 93 civic.

it's been working perfectly fine until i took out my transmission.

basically my speedometer just jumps up and down.

while i reverse slowly, it jumps, when i rev, it jumps but when im still it doesn't jump.

i've tested the volts and the ground and the voltage when the vss spins and it checks out good.

is it just a faulty vss?

i took it apart and cleaned it up a bit with some brake clean, put it back together but still nothing.

 

Check for a loose wire or corrosion on your vss plug.

 

sounds like the clip on VSS might be broken?

take it out..clean it and put it on there really snug

i had the same problem and i fit it in and never happened again

 

No corrosion and all wires are good.

 

the clip wasn't broken but yeah i took it out and i just put it in really snug and made sure the clip clipped on and it was fixed! Thanks for the input guys

 

No Problem..
those tend to get loose at times

 

Is there a electronic VSS that would actually bolt up to a 90-93 integra transmission?
