In the past 2 weeks my low traction light has been coming on when it shouldn't. Bumps, uneven pavement, coming to a stop and taking off from a stand still are all causing my low traction light to blink and come on. But gravel roads or wet roads don't, basically road conditions you would expect it to come on it don't. And every once and a while it stays on and triggers my no traction and abs light to come on. I am hoping its just a sensor or something easy, just dont know how to diagnose it. please help.

I have three 1997 Olds Cutlass's. They do it to! Nothing to worry about. They will do that in response to a bump, or washboard road driven over at a certain speed. The wheel speed sensor on each wheel tells the computer how fast each wheel is turning. If one wheel speed is faster than the other three, as when you hit a bump, the computer thinks it is loosing traction and flashes the light, and may or may not engage the ABS system to even up the speed on all four wheels.
Now if that light comes on, and STAYS on, that is another matter. It will only do that if a wheel speed sensor becomes faulty, and then the ABS light will override the traction light.
TAKE CAR TO A GARAGE OR DEALERSHIP HAVE THE ABS BRAKES AND TRACTION CONTROL CODE SCAN.YOUR ABS BRAKE SYSTEM WILL COME ON ADJUSTING BRAKE PRESSURE TO AVOID A SKID.THAT WHY LOW TRAC LIGHT COMES ON. MOST OF THE TIME WHEN YOU SEE LOW TRAC LIGHT DRIVING ON DRY ROADS PROBLEM IS IN THE ABS BRAKE UNIT OR BAD WHEEL SPEED SENSOR.
If your ABS light is on as well, have a shop scan it (it requires a special scanner). If it's just your Trac light without ABS, it is most likely a sensor under the hood at fault. If you are getting a check engine light as well, get the codes read!
This happened to me without an ABS light and it was the upstream O2 sensor. The reason it throws the Trac light is because if any components that the traction control uses (ignition, fuel) are affected by a bad sensor, the PCM shuts down traction.
In fact, when I replaced the O2 sensor, a handful of other little issues resolved as well.
If you do have an ABS light on, it could very well be a wheel speed sensor.
Ok, check the brake fluid level for a start. This could mean a few things. Your brake pads might be worn down, which would bring a yellow warning light on(triangle), at the same time with the pads being low it will have displaced the fluid, making the level low, this would be a red light on. Now because of this the body control module has detected these faults, will have turned the abs off, hence the abs light.
If brake fluid is low, this could confirm my theory.
If its low, top up with dot 5 brake fluid and take to garage to have new pads fitted.
