How do you fix your speedometer on a 99' Ford ranger?

Answer by  James916 (539)

You probly need to replace your VSS, Vehicle Speed Sensor. This is usually located on the top of the transmission. It should just unscrew and you can screw a new one in. This should fix the speedometer.

Your speed is off because you have changed the drive ratio Either the tire diameter/height or the the rear-end gears are different. This is causes wheels not turning the same amount for every rotation of the drive train. Either change the rear-end gear to the appropriate ratio or install the correct speedometer drive for your current setup.

You probably have a loose speedometer cable. Check and make sure that all connections are tight, so you're not losing any of your rotation. Also, an old or bent cable can cause this, so you may need to replace it. Speedometer cables can be a bit tricky to replace, but you can do it!

Sometimes the wrong fuse can do this. The fuse controls the wipers and dome light also. Otherwise, it could be too large or too small a tire that is on the truck that is messing with the spedo as I know.
