2002 Buick Regal Anti lock brakes Troubleshooting

[Chevyman22360]

I have a 2002 Buick Regal LS. The service vehicle soon light come on. I had the codes checked and both the front left and the front right wheel sensors show bad. I checked the wheel bearings on both sides everything seems tight. Also checked the wiring and connections and don't see anything. Is there a way to test both the sensors and the harness with a multi meter? What should the readings be? Thanks for any information.

Yes, you can test the resistance with an ohm meter. Not sure of the specific tolerances, but the front and the rear are supposed to be the same, there's plenty of videos on you tube, should give you a general idea of what to look for.

Just so you know, the bearing and the sensor, even though it is all one unit, is actually to separate units melded together. Even though the bearing is tight, the sensor section may not be working.
