Recently my speedometer stopped functioning properly. First it would only come up after I passed 30 mph or so, then the other day it stopped working all together. The truck seems to still shift fine, what should I be looking for?

Hello,

It sounds like you have a vehicle speed sensor that is going out and it needs to be replaced.

You will need to jack the car up first

Here is a diagram of the sensors location so you can get the problem fixed.

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

This happened to me on a 99' Ranger. Ended up being the speed sensor in the rear end was bad, simply replaced it, and it worked perfectly. I didn't get the lights on the dash, but I didn't have overdrive. Mine was a standard also.

hi, my speedometer is not working. After shifting into 4X4 LOW a couple weeks ago, the speedometer stayed at 50 mph. Before even starting the engine, it reads 25 mph. When started, it jumps to 45 mph. I replaced the speed sensor on the rear differential but the problem still exists. What next?

Did you stop, put vehicle in neutral and shift into 4low?

As soon as it wnet into 4 low speedometer jumped to 50?

Or when driving it jumped to 50 and stayed?

I really need those details to find out whats wrong. But it could be a possible issue with vehicle speed sensor, I belive you may have one in the transfercase also.

After doing research (and help from local auto parts store) I believe that the problem is the 4WABS brake module. All information from the sensors are sent to the brake module.

I really wouldnt put that at top of the list for speedometer reading considering the speedometer doesnt read off of the wheel speed sensors.

Only the vehicle speed sensor. Or cable.

But in '96 or '98, ford stopped producing vehicle speed sensors (VSS). They are now controlled electronically.

Sorry im alright
wasnt paying attention to the year.

Fords did stop in 97 with their new line of 150's and 250's

the vechicles get their reading from the wheel speed sensors and collects it from the 4wabs module.

If you would like I can explain how to test it.

Bit confusing though.

But if you have a code for 4wabs then id fix the module first.
