Speedometer starting to fail

[TheNewt10]

While I'm driving my speedometer falls to 0 then goes to the speed I'm driving in. And sometimes it stays at 0 an it will take a little time for it to start working. What can I do To fix that problem? Getting annoyed of it.

Replace your vss(vehicle speed sensor). I just replaced mines and its working so far. Should take like less then an hr. I bought mines off eBay for like 10$.

I would check your vss, and go from there. It is located behind the head a little low, on the drivers side. this youtube video will help, tells you how to trouble shoot, locate and replace the vss, also tells you how to look for signs of damage. http://www.youtube.com/watch?v=GzxQ1I8mI_4

Before just replacing the VSS, make sure it is the VSS. The speedometer, odometer, and cruise control all rely on the signal from the VSS. If the odometer and cruise control stop working at the same time as the speedo, then it is likely the VSS. If the odometer and cruise continue to work, then it is probably just the speedo.

Exactly. The VSS is most often the culprit, but it's not always.
Doesn't the VSS usually throw a CEL as well?

[TheNewt10]

Well I haven't bought the vss yet and it stopped doing it. Hopefully it doesn't start doing it again. And I'll test the cruise control and see if it works

[Fleetw00d]

If speedo is working, then cruise should work as well. The thing to watch for is if the odometer is still working when the speedo quits. If the speedo quits, then see if you can set the cruise.

^^ ur last sentence... will he have to get a new cluster then?

He wouldn't necessarily need an entire new cluster, but he would probably have to buy a whole cluster from a salvage yard for parts (doesn't hurt to have extra bulbs and other components). The cluster can be removed, disassembled, and just the speedometer can be replaced. I had to build a frankenstein cluster for my wagon. The printed circuit board (PCB) was corroded in an area that affected the speedometer and odometer (after I'd replaced the VSS - didn't do enough troubelshooting). I would up picking up two other clusters from sedans (1 to get it working while my daughters had it at school, it had corrosion issues as well), then another at home with a good board. I was able to keep the same odometer. I had to swap out the original wagon speedometer (up to 140) and install the sedan speedo (up to 130) to get it to read correctly with the sedan board. I may still have a spare speedo around.

Thank u mr Wood. I'm glad I asked that question because I'm sure I wasn't the only 1 who was wondering..

Taking that cluster apart is a bit scary. Very delicate. Make sure you remember what screws go where. I got lazy put the wrong ones in my temp gauge and runined it.

Wow never knew that a vss could be the reason behind my speedometer not working. Not sure if I should check my vss first or just buy a new cluster

hey guys, my speedometer is pretty off, in the lower speeds it'll be right till about 40mph, then it'll be 5 ish mph off, then the faster i go the more it goes off, like on the free way when I'm going the same speed as everyone it says I'm going 100 and I'm obviously not. Would replacing the vss sensor fix it or would i have to replace the cluster or something?
edit- everything else works fine.

It's more likely to be the VSS than the cluster itself. Is your check engine light on?

You are probably running a different tire size than stock. Put stock size tires on your car, and your speedometer will be correct again.

Yes my cel does come on after a certain amount of time and my odometer does work intermittently and after some research last night im going to try and change the vss first before the cluster
