I drive 17 year old beater, it's a 1992 Ford Ranger 4.0L 5speed and I don't even wash it anymore cos of all the dents & scratches what's the point? Anyway, this past week the light on the dash that says Rear ABS has been coming on. I was told to get a sensor for it - which I installed yesterday (first day it wasn't raining) but today the light came back on again The brakes work great, although I dunno about the ABS part. I've taken that poor little pint sized truck everywhere, mud, dirt, gravel, - including muddin in the Mississippi river spillways. It brakes and handles great as small pickups go, but I wouldn't say the ABS part has ever been very fast to "kick in" because I think it's only done it once. Nothing has changed in the way of handling or braking so I'm wondering why the light is coming on all of a sudden? Fishing for ideas here because If it's not the sensor - what could be wrong???
