95 PAU traction control light

Traction control light comes on after a short time after car start moving.
I can make it go out by stopping, pressing the traction switch, but soon after the car is moving again it comes back on.

I am hoping it is a speed sensor, and not the transmission. Is there any way to:
1) bypass the speed sensors in am attempt to isolate a bad one;
2) can I test one of these w/o a code reader?

Check for a tire low on air.

The traction control / abs system uses sensors on the back of each wheel hub to detect the rotational speed of each wheel. If a wheel is rotating at a diffent speed and the brake is applied, then the ABS transfers braking to the other wheels. If you are not braking, then a tire is slipping and power is transfered to the other drive wheel.

A tire that is mismatched in size with the opposite side or a tire that is low on air while rotate at different speeds causing the light to come on.

Good point, I will check this out first.

exactly what he said, if not scan for codes...
