Hey everyone, I got a 2000 Ranger Sport with a 4.0 and I got a big problem. I went to turn my truck on and my abs light won't go off. And on top of that my speedometer doesn't work. all my other gagues do though except for the seepdometer. Please help!

 

well i just went out to test my abs and see if it was just a little blunder by the computer in keeping the light on but my abs did not kick in. so if anyone has any ideas as to what might be wrong please reply.

 

my 93 with rear abs would occasionally light the abs light after starting the engine, my speedo never had a problem, so i am guessing that this is differnt

Since ABS is a speed related system, the system may have been telling you that it was not recieveing the correct input from the speedo --

if the speedo is not working, focus on that, -- the ABS issue will probably clear up when the speedo issue is fixed.

I can't be more specific, but i hope that gives you someplace to start

 

Welcome to FTE!!!!

Your RABS sensor in the rear dif. is bad, or the connector to it.
This sensor is used for the RABS, the speedometer, and the
transmission shift points. Your transmission is probably shifting
funny also......

 

well as far as i can tell it's been shifting fine but i'm taking it in tomorrow morning, probably gonna have to miss my classes tomorrow, one day missed so i can pass the rest of the semester is a small price to pay. i'll post up what happens...thanks guys.

 

well i just got my truck back and it turned out to be the rear wheel speed sensor that was causing all the problems. thanks a lot for helping me figure out what the problem was.

 

Howdy folks,

Great forum. I've had a similar problem with my '99 XLT (3.0L 5spd 2WD) - just started about a week ago where the ABS light came on and the speedometer stopped working below 40MPH (above 40MPH everything went fine - although ABS light stayed on).

How difficult is this sensor to get to? Is it something a mechanically inclined novice can attmept to replace or am I better off taking it to my mechanic?

Thanks for any additional feedback.

Dave

 

the sensor in the diff. is held in with one single bolt.this thing is easier to change than a taillight bulb!!!!!!!!!!!

 

by the way my ranger is a one owner "ME" 1993 splash 2.3L 5spd black/grey with only 155,000 miles!!!!! only change is wheels/tires.

 

Picked up a new speed sensor today ($19.00) and installed it. Problem appears to be solved. Thanks !

 

About a month 3 months ago, I had my rear axle and u-joints (not certain exactly new to the under carriage) re-greased and approx. a week later ABS light comes on intermittently at about 40 mph while in third. Could it be possible the shop loosened a connector to the RABS or somehow offset the Speed Sensor? Where is the RABS connector located on the 94 Ranger XLT Extended Cab?

The RABS sensor is located on top of the rear differential. I just changed mine on my 94 one bolt is all that holds it in plus the electrical connector.
