What issue are trying to fix? ABS or speedometer?
Speedo uses the rear differential sensor and the ABS uses the rear differential sensor and front wheel speed sensors.

I would check the ABS codes, and check that rear differential sensor and wiring. If yo look at the back of the differential you'll see the sensor with 2 wires going to it.
