At first it would go out by doing the reset, but only temporarily. Now it will not go out with the reset. The wheels needed cleaned and paint touched up, so while doing that I cleaned all the wheel sensors, to no avail. They looked pretty clean anyway. Drove the car, BAS on and the other symptom is the spoiler will not actuate at speed, nor will it retract when slowing. It does work fine with the dash button. No flashing light on spoiler button. It looks like my traction control switch does not actuate the dash light , no matter which way I move the switch?? Making progress, but this car is more neglected than the free one we were given 4 years ago. Of course it has less mileage as well. Any help would be appreciated. Oh, is the left front wheel speed sensor different looking than the other three sensor heads? It looks to me it has a magnet on it?
