1999 Ranger XLT, 2 WD

Last year my speedometer was jumping around and ABS light went on. This forum directed me to replace sensor, no problem, took 2 minutes.

It fixed the ABS light but still no speedometer. Tried a second sensor, same problem.

Is there a way to diagnose the system? Is there a fuse? What V should I find at the sensor?

One year without a speedometer sucks, but I haven't put any miles on the truck...! I really would like this fixed and I don't have time to drop it off somewhere...

Do you have 4 wheel ABS or only rear ABS?

 

I have a pretty basic model of the 1999 Ranger XLT. It has roll-down windows, if it is an issue of 2 or 4 wheel abs it probably has 2. Is there an easy way to tell?

The sensor is exactly as described-- 3/8" bolt, easily removed and replaced.

All fuses for speedometer etc have been checked and are operational.

I removed the rubber boot from the sensor connector and the wire has a crimp in it. It is possible that it is open, I'm going to try to bypass the spot. I don't think this is the issue.

Thanks for your help. I really appreciate it.

mr scopion

I am having the same problems. My ABS light came on and then my speed-o started to act up. The speed-o does not work untill the truck gets above about 35 and then it works like normal. Did you find a soultion to your problem? What did you do?

You dug up two really old topics for this lol.

Yes it's the speed sensor on top of the rear diff. If you buy it it's probably under vehicle speed sensor or ABS speed sensor. Held on by a single 3/8" bolt. It's up on top, driver's side. Easy to replace.

 

Its the ring gear sensor at the rear diff, 60 buck fix (have a shop do it and you stay clean).

 

Orrr....do it yourself, and it's an $11.99 fix that takes about five minutes.

 

zach, your right, i'll watch you while i suck on my slurpee.LOL.

nah, it is a DYI project. plug and play deal. shoots, he could have gone to parts store and back. replaced and tested his truck and we would still be sitting at our computers, on a saturday morning.... how is that!

 

Lol. That sounds about right.

 

Yes...that is what it was. I replaced the sensor and I am back to normal.

$15 and 20 minutes.

Thank you very much!

 

Glad ya got it fixed.

 

Zach

I guess we were correct. He got the parts, fixed it, tested it and we are still on the computer.

Where's that slurpee.

oh. congrats on the fix!

 

I am not sure about a slurpee...

But I am drinking a beer for you guys now.

LOL...

Thanks again!
