traction control on 2005 Chevrolet Impala

My traction control seems to engage even on a dry surface. In addition, my traction control sensor light will come on my dash as well as my ABS light. Is this common and what do you think is the cause as well as the repair cost?

I think you may have one or more ABS wheel speed sensors malfunctioning. This could be because of faulty sensors or simply that one or more sensors are fouled with metal particles from the brakes causing the magnetic sensor to lose it's ability to give a distinct signal to the controller. I've been able to clean ABS sensors with a blast of compressed air (using appropriate safety goggles and face protection) and that's relatively easy. If that doesn't work or not an option, see a mechanic who does ABS and traction control system work. Here's a directory link for you:
