Traction control issue

Hi everyone,
I have a 2009 LT with a 2.2 liter ecotec. Recently my traction control light came on and is staying on. Engine light is not on. The ESC light is not on. And there has not been any codes at all when I've had it scanned. There is no hard shift and the car is acting and driving normally. My hubs are also in great condition. I'm stumped as to what is causing this issue, as I have tried the "quick fix" methods I have seen. Anyone out there got any ideas or had a similar problem? I do all work on this car myself, but this has me stumped.

How are you sure the hubs are in "great condition"?

My first guess is one of the wheel speed sensors is unplugged/wire broken/faulty.

What "quick fixes" have you seen?

Traction control

Hubs are new. Quick fixes such as turning car off and on, disconnecting the battery, going to check wiring next as well as sensors.

Look for damaged or broken wires and loose connections at the wheel ABS sensors, ground wires loose? Clean?

Traction control

Will do. When I replaced my rear abs harness on the rear last year, right side clip going in to the right hubs wasn't snapping fully into place but still connecting, as one side clip was broken off. So it could be that one...stupid me just remembered it a bit ago. Gonna go thru car tomorrow. Will let you know..and thank you.

You will need a code reader that can read traction control/ ABS codes.

A standard check engine code reader can not.

Most likely one or more of the wheel speed sensors is damaged/wire/connector.

Took your advice. Went and had problem scanned the right way. Turns out T/C light is on due to a bad steering wheel angle sensor. That was the last thing I would have thought of. Have one on order. After install it needs software update and alignment. Thank you for your insight.
