Speedometer Problem

01-18-2008, 09:02 PM
Only my speedometer in my dash doesnt work anymore and stays at 0. It happened when i was driving home and my guage jumped to 80mph then back down to 0 mph and happened 3 times till it died. It's not stuck so I checked the ecu and it read 55 then I changed my speed sensor thinking it will fix it. That doesnt work so I'am thinking it's the guage and I should replace it. I dont like paying mechanics when i can do it myself but I'am stumped on how to do that operation carefully. If anyone knows how to replace the guage or any good websites instruction's; please post.

I almost got a speeding ticket for doing 40 in a 25 zone.:runaround:

Using the manual


you can check the speed sensor. If it's not there work upwards along the wiring. Provided there are no breaks or bad contacts you can probably assume it's a bad or broken connection in the dash unit, which, unless you can find the exact solder joint that's broken or burnt, will require a replace gauge cluster.
