Have brakes checked out ASAP, you should still be under warranty.

Is the sensor tone ring in the bearing or on the side axle. If the ring is internal to the bearing have you replaced the bearing when you replaced the sensor (sold as one unit normally, aftermarket). If the tone ring is external, check it for cracks or loose fit on the axle. Also the wiring integrity of the sensor from the connector in the wheel wheel back to the EBCM (electronic brake control module) should be checked as well. hope this will help you
