Check the wiring to sensor that runs along the lower control arm first. Look for damaged wiring/cuts/frays. It will connect to a jack located at the hub. Remove connector, check for corrosion and clean with electrical contact cleaner and re-install making sure it it tight. This must be done for all four wheels since you do not know what sensor is bad at this point in time. If wiring is OK then the complete hub/bearing must be replaced since it comes as one unit. To determine which sensor is acting up you need to have it scanned with an ABS capable scanner, otherwise you can only guess as to which one is bad. Normally it is the front ones that go bad. Good luck!
