More likely internal abs module if you get intermittent wheel sensor speed issues. There is a design flaw how the connector is wired to the motherboard. You can swap a couple speed sensors to test if it's the sensor (move and the problem migrates).

That said the sensors are very sensitive and rust on the sensor or bearing will throw them off.
