Probably a faulty wheel sensor........, or you may find that you have a faulty wheelbearing. I experienced the same exact issue. In my case, normally the Low Trac light would come on when accelerating from a stopped position. It seemed to happen more frequently when the steering wheel was turned in either direction while accelerating from a stopped position. The movement or slack in the bearing albeit very slight is enough to change the condition(position)of hub to sensor which the difference is enough to trip the sensor causing the low trac light to come. The wheel sensor is most likely doing its job and the faulty bearing is your root cause. The wheel bearings are a sealed bearing. Had passenger side go out @70,000, driver's side @90,000. I changed the wheel bearing in both cases and the light has never come on again after driver's side was replaced. I learned the best case is to fix both left and right bearings at the same time as a pair.

What exactly does the second gear start switch do on your 1994 Pontiac Grand Prix SE?

the second gear start switch is for ice or wet conditions. Tthe car starts in second which makes it easier to not spin the wheels giving you better traction NOT FOR NORMAL DRIVING OR PROLONGED DRIVING use it only when you need it I think it is when you step on the gas, the car doesn't go forward until it is in second gear. Good for wet or slippery roads.

What is traction control in cars?

Traction Control ensures that there is enough traction i.e grip. If there will be too much power or a car might be on a frictionless smooth surface, the car might skid due to less traction and TC regulates power and ensures seemless driving

Sand absorbs heat from the sun more readily, helping to melt the ice. More importantly for driving conditions, the texture of sand gives drivers traction.

What causes the trac light to go off in a 2001 grand am?

There is a push button on the shifter right where your thumb is, that is the trac button. Under normal driving conditions keep it off. Turn it on when it is wet or snowing for better traction control. If you have problems with your abs the light may stay off permanently as the traction control feature is actually the automatic application of the brakes to maintain even traction between the drive wheels.

What affects traction while driving?

road conditions, such as surface material, (rock, gravel, asphalt, cement), weather conditions, (temperature, wet conditions, dry conditions), tire conditions, (tread design, tread depth), tire inflation, tire composition, (softness of rubber) vehicle weight and speed, tire movement other than rotation, (straight line or turning). and probably a dozen other things..

Most effective for all conditions is undoubtedly all wheel drive, or 4 wheel drive. Most driving conditions only require 2 wheel drive. Subaru has an excellent system that is normally 2X, and switches to all wheel as needed, as slippage starts.
