My services traction light comes on on my 05 chevy impala and my abs light doesnt go off neither does my trac light. What could be the problem? and how much would u think i looking at in cost to fix it?

Very common problem. The MOST LIKELY cause is that you have a front wheel speed sensor that is not working properly. This could be due to a bad front wheel bearing assembly or it could be a wiring problem. GM has had a LOT of problems with the wiring harnesses. A company named "DORMAN" makes a harness repair kit. (See picture below) The Dorman part number is: Part Number: 970-041 The wheel speed sensor itself and the wheel bearing come as a complete "HUB" assembly. The wheel bearing should be checked for looseness and the speed sensor should be tested at the speed sensor connector for AC voltage output when the wheel is spinning. If the bearing or the sensor is bad, then you must replace the hub assembly. If this is the case, I recommend using the "Timken" hub assemblies. They are more expensive, but are much better quality. I have had many problems using the cheaper brands. (See picture below) If the wheel bearing and sensor is OK, then the harness should be replaced. You will have to scan your Antilock Brake System (ABS) module to find out which one is causing the light to come on. As far as cost...it depends on exacltly WHAT it needs and WHO is doing the job. There also may be more than one speed sensor giving you problems. Your best bet is to get it diagnosed and get an estimate of repairs. If they try to sell you a hub assembly, ASK them if they actually TESTED the speed sensor. MOST mechanics out there will just throw a speed sensor (hub assembly) at the problem if they have a speed sensor code, only to find out later that the problem is in the harness. Of course, the customer is the one who ends up paying for their incompetence when this happens.

{: ) The traction light is only an indicator or warning, it is just being erroneously triggered by the real problem which is the ABS. Fix first the ABS concern and the traction light will normalize as well. The ABS light tells there is something wrong with the antilock brake systems of your vehicle. It could be one of your wheel speed sensors. But to be sure which, it is recommended to have your vehicle scanned by a diagnostic scan tool to know exactly the components at fault.
