98~2000 use the same diff housing sensor for the rear axle ABS and for the raw VSS pulse. Speedometer correction for tire size is done in the GEM for RABS or in the 4WABS Module for 4WABS.
2001~current have the rear diff ABS sensor but there is a separate Output Shaft Speed sensor on the transmission that supplies the raw vehicle speed pulse to the PCM. The OSS reads a tooth wheel on the output shaft. Speedometer correction for tire size and axle ratio is done in the PCM.
95?~97 also have the rear axle ABS sensor but use a gear driven VSS signal generator on the trans or transfer case. Speedometer correction for tire size and axle ratio is done by interchangeable gears similar to a speedometer cable.
ABS:
RABS trucks use only the single diff housing ABS sensor. 4WABS adds individual sensors at each front wheel. All Rangers have had standard 4WABS since 2001.

Sorry to bring up an old thread but I think this is pretty much my problem (ABS engaging on flat roads and slow speeds). So how can I disable the ABS or what is the best way to take a look at the ABS sensors to clean them? I am not sure what they look like or where exactly they are located. Any help would be appreciated. Also if anyone found a fix for this please let me know. Oh yeah I am running 31's on steel wheels.

I tried but the OD light would blink and shift pretty bad also I lost the speedo. I think its a fail safe so you can't mess with mileage (odometer would not spin). Anyone else have this happen when they pulled the #14 fuse in the cab box?

I have this problem to I went to a local repair shop to try and get it fixed they replaced the front left sensor and the rear sensor and it cost me $450 dollars.
a week later it was doing it again,
took it back got the front right cleaned off and still does it. I guess I just have to live with it.
