Sometimes it takes more than 20 minutes for a reply. Give a few days for more responses.

Sorry I can't be more help as I do not advise on issues I've never experienced. Someone else my have some advise. Stay tuned...

It's pretty common. Mine goes all the way around the other way and sits there untill i rev it out all the way to 5800-6400 and it'll come back down the right way. Then is it fails to the stopper at 0 you can hit the trip reset button and that often puts it back to readings the revs. Most suggest replacing the unit in whole. It really sucks.

Are you serious? Whole assembly? WTH?! So there is no way to fix this myself?! Another annoying problem with this car!!!

Anyone have another one laying around? I'll buy it. the car only has 31K on it. can this really happen?

Bring it in to the dealer and they can fix it - might be cheaper to buy a used assembly. I'm not really sure, i've sorta ignored it a lot.

It has to be some sort of sending unit mechanism or similar. i just don't know enough about the way it is wire to be of much help.

hollywoodstang:

If your speedo is not working, check the fuse first. The VSS (vehicle speed sensor) is a little AC voltage generator on the transmission. The gear may be stripped. If it is, replace it (it just pulls off). If the gear is in good shape, hook up your VOM (volt-ohm meter, voltmeter, multimeter, etc.) to it and see if it generates AC voltage when spun. You may need to use a variable speed drill to generate enough RPM/signal to read on the VOM.

If your odometer has stopped, it is most likely the little internal gear. Run a search and you'll find plenty of people with this issue and the links to find the replacement gear. "carradio.com" is one spot that has high quality gears for sale.

HTH,

Chris
