Could be a bad wire harness to the sensor.....how long ago was the wheel bearing replaced? Why was it replaced?

New doesn't mean good. Have seen if the installer didn't get the connector onto the bracket, the wires would rub on the axle shaft. Have also seen bad wiring inside the wire harness at the lower control arm. If the problem didn't show up till the new bearing was installed. I'd go toward the bearing first and check the wiring at the hub.

I would inspect the connection where the wheel bearing electric (speed sensor) plugs into the wiring harness. Should be fairly easy to do, jack up the car, place jack stand, and remove the left tire . You should be able to visually check to make sure the connection between the male and female connector of the speed sensor at the wheel hub are snug and free of corrosion. Also do a visual check for a cut wire. My guess is you have a bad connection, either from a poor connection at the point of where the hub electric plugs in, or a cut/ frayed wire near the hub. If not that, exchange your hub under warranty.

I have an '03 Impala that the traction active light kept coming on, then after awhile I would get a message that the traction was inactive or something like that. No codes set. When it was raining all worked great so I was thinking there was an intermittent open somewhere in the wiring . I remember hearing that the driver side wheel sensor wiring could be flakey. So I ordered the repair kit, new connector and long wire leads. I cut the old connector wires off as far up to the main harness as possible, the crimps that came with it were impossible. I soldered the wires , then heat shrink. I removed the factory wiring hold downs on the lower control arm and used long wire ties.
