If you look under the truck, near the left rear side of the transmission, check for a cable secured to the transmission by a bolt and clip. This is the speedometer cable, which is probably broken in your case, if it is a 4x4 truck, the cable is on the left rear of the transfer case. You can buy just a cable from your parts store, pull the cable from the housing, it should have a square end about 1-2 inches long on each end of the cable. The cable is secured to the back of the speedometer by a spring clip. If you pull out a cable that is not suare on both ends, it is broken!!
On a 1995 Ford Ranger : The ODOMETER is near the center of your speedometer
Speedometer is ran by electronic sensor on rear end. Odometer is ran from speedometer. If both don't work problem is sensor. If speedometer works sensor is okay. If speedometer works and odometer does not problem is in mechanical parts (gears) of of odometer and has to be replaced. Can get used from eBay (search for speedometer or odometer, is one unit) or take to dealer.
Your speedometer may have failed, or the speedometer cable that connects to the transmission, or the plastic gear in the transmission may be broken.
If the speedometer works but the odometer does not work, you have to replace the worm gear on the back of the speedometer. you can buy one from: SPEEDOMETER GEARS.COM part# 10-021w 95-99 ford explorer/ranger/f-series price includes shipping inside the u.s phone # 1-800-446-2880
A worn or frayed speedometer cable will make the speedometer shouter. As the speedometer cable becomes more frayed the speedometer will eventually quit working.
Check to see if there is a sticker on the end of the driver's door showing the original size of tire , and compare that to what is currently on the Ranger. Any change in tire size or wheel/tire combination if it is not a similar diameter as the factory set up will throw off the speedometer.
my ford 2001 ranger had the same thing happen to me i sent to the ford delear for repair and it was a missing fuse so check all fuses
If the speedometer is still working and the odometer isn't, then you have an internal failure in the speedometer head assembly. Everything is self contained and non-servicable. It can only be replaced as an entire assembly. There is a microproccessor(computer) in it that uses vehicle speed information provided by the vehicle's data network to operate both the speedo and the odo. If one of those two is operating but not both, then the speedo head is getting the input it needs from the network, and processing it. Whatever componet is not operating has failed, but it is not servicable without the entire assembly.
speed regulator sensor needs replacement
I believe the fuse that protects the speedometer also protects all the gauges in the dash cluster, so if that fuse was burned out all the gauges would be dead. If only the speedometer is not working I would suspect the speed sensor in the transmission to at fault, if the wiring checks okay.
If the ABS light is flashing it means the system is malfunctioning but still working. The dash light behind the speedometer is burnt out.
Trans output speed sensor.
