Did you clean the "wheel" with the holes in it that the sensor reads? Many times, ABS problems are dirty connections.

It could be a bad sensor or a sensor out of adjustment at the wheel. If it's just adjustment it can be adjusted without taking the wheel off but with this crap they put on the road in the winter you probably have to replace the sensor and the holder. To adjust the sensor follow wires up to the sensor at the back of the drum and push the sensor in as far as you can and once you start driving it will self adjust back out for it's gap.
