Although fairly rare, could be a faulty sensor that came with the bearing assy. Watch the scanner while driving to see if it is seeing that particular wheel speed vs. the other three.
so a customer came in with a bad wheelbearing swapped it out, and then the abs light came on and got a code for that wheels sensor. so we swapped that out for a new one and the light remains. we put dielectric grease on the connection at the sensor but the problem persists. cant figure out where the signal/power is being lost. help? ![]()
