We’ve had our Gran Am since 2003 only two years old when we bought it. Treated well, serviced when needed. The last 3-4 maybe 5 years we have the traf light coming along with two more. Don’t recall their names right now. Mechanic puts the scanner on it and it says it’s the front right speed sensor. I replaced it 2-3 yrs. ago and still it comes on randomly. I checked the wires at the sensor as far as I could see and see no chafing or bad wiring. Someone have a clue as to how to check further?
