I replaced all of the struts on our 2006 Grand Prix yesterday (garden variety 3.8 liter) and broke off the left rear plastic ABS/traction control sensor housing in the process. It was a clean break around the base of the plastic, so I ran a bead of super glue around the edges of the break, pushed it together and it held solid, but I ran a bead of glue gun glue along the exterior of the break just for good measure. Now I am getting the check ABS light and traction control off message from the dash.
I have not tried to reset the dash display or run an analyzer, but I think the problem has to be the cracked sensor housing. I have seen numerous threads on this board that suggest these sensors are not replaceable. Is replacing the whole hub really the only solution?
