Just because the wheel sensor resistances are all the correct value of around 1K ohms doesnt mean they are good. Connect a DMM set on AC millivolts to the suspect sensor terminals at the ABS computer connector. Jack up the wheel associated with that sensor so it can spin freely, and give it a good spin. You should get 50 mV to 750 mV, depending on how fast the wheel is spinning. A good spin by hand usually generates around 100 mV to 250 mV. If voltage is low or irratic, inspect exciter ring, and sensor - exciter ring spacing.
