well the other day my 97 dx hatch speedo started going nuts ........ so i searched and researched the problem ............

so i replaced the gauge cluster with a known working one still same problem....
so then i replaced the vss with 3 different ones from the junkyard........
then i cleaned the plug that goes to the top of the vss.......
still nothing !!!!!!!!!!!!!
so i ordered a vss from honda brand new installed it today and still nothing
so i took my buddy's ecu out of his 97 dx and still same problem

my searching threw honda-tech ive seen that many people have had similar problems and never posted a solution to the problem ........ so now im asking for your help ...... oh and the car is throwing a cel for the oxygen sensor bank 2 but no vss code

 

you're gonna need a voltmeter to track down the short, maybe a ground wire is off somewhere.

 

i checked all the grounds and cleaned them off ........ and frooze my *** of doing it today it im just glad i have pleanty of other cars to drive !!!!!!!!

 

i dunno if there was a bad fuse somewhere which i would highly doubt but thats about the only thing i didnt check

 

i bought a speedo with tach from the junkyard for my eg, and ever since the speedo goes haywire and stops working if i go 45 or 75 for more than a minute or so straight, or if it is wet or really cold.

I cleaned all the contacts on the PCB and connectors, but no luck. I just blame it on the shitty junkyard cluster that was sitting exposed to the elements for months

 

I had that problem on my civic, I took it to an auto electrician.

He fixed it and told me that a farly common cause is a cable rubbing on the intake manifold, round behind the engine, you need to get the car up in the air and look for it from underneath.

HTH

 

someone help !!!!!!!!!

 

might be ground to ECU, I had a similar problem a few years ago.

 

where is there a ground for the ecu located

 

Try disconnecting then reconnecting it first.

 

My buddy had a similar prob. Just doing like the 15mph the speedo would go from 15 to like 120 and back and forth. He took it everywhere. Ended up being a 5cent fuse

 

guess im going to go check my fuses ???

 

help !!!!!
