SOURCE: 2001 olds ABS and traction control sensor issue

An ABS sensor DOES affect the traction control system. Traction control uses these sensors to determine if a wheel is losing traction. A bad sensor will cause both the ABS and TRACTION lights to come on.
The CHECK ENGINE light however is going to be a seperate problem.

I have a Mazda Capella (626) 1998 and had similar problem other than it was running on 4 cylinders and the hand brake light was not on but speedometer was not functioning and the ABS light was on. The rear ABS senssor was the problem.

SOURCE: brake sensor? something else?

You have a faulty wheel speed sensor. This is a magnetic pick up sensor on your wheel bearing hub and it controls your abs. If the car can not sense all 4 wheels then the abs will default back to normal brakes and your traction control will not work. Look at your wheel bearing hubs and check for these sensors. They are on the underside of the car and are black plastic with a wire comming out of it. A piece of gravel may have broken the pick up or the wires to a sensor may be broken as well. To replace it is usually a couple of screws on the hub assembly and a plug to disconnect from your wire harness.

My 2002 Millenia just started doing this the other day, while on the freeway when it started doing it i would shut engine off and restart it and it would be good for a while then it would do it again, i am still looking for solution, has any one found one?

THESE LIGHTS RESET AUTOMATICALLY WHEN THE SYSTEM IS REPAIRED, AS LONG AS THERE IS A FAULT IN THE SYSTEM THE LIGHTS WILL REMAIN LIGHTED
