ABS Questions(2001 Ram 1500)

Get a volt/ohmmeter and check the two pins on the rear sensor. If it's bad, it will read an open circuit. If it's good, I believe it's supposed to be around 2K ohms if I remember right. You CAN get bad parts from time to time. Also check the fluid level. Stupid as it sounds that can sometimes do some screwy things. If the rear sensor checks good, you can remove it and make sure it is CLEAN. More times than not, it's always somethin simple.
