I have a 2002 buick rendezvous with 79000 miles. I recently received a message that said service traction system and it turned off both the traction and the abs. I could feel the traction working and the brakes would pulsate. I hooked it to a scanner and it said the left front abs speed sensor was bad. I changed it and it worked fine for two weeks. Then the brakes started to pulsate again. Eventually the light came on again. I hooked it to a scanner and it said nothing was wrong. I checked the fuse for the abs and it was fine. I changed the left rear abs speed sensor because that wheel was out of sync in speed with the other three, but never tripped a code. The problem persists and the light continues to come on. Any ideas what else is wrong?
