My ABS kicks in sometimes when I brake on a rough road and the other day right after the abs kicked in at a light I then tried accelerating and the ATC kicked in. Its only happened this one time about a week ago and I've put some miles on the car since. Bud of mine said that my wheel sensor might have had some dust or dirt on it which caused this to happen. I was thinking that maybe the "sensitivity" either on the throttle body or wheel sensor needs to be adjusted-is this possible?
