Also check tone rings they sometimes break or get really Rusty and don't give good communication to the wheel sensors . First thing I do is remove each wheel inspect tone rings clean them with a wire brush then remove wheel sensor clean with brake cleaner also spray out sensor hole. You can also check wheel sensors with a voltage meter and spinning the wheel . Search the web there are videos on how to test wheel sensors with a voltage meter
