Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.

Expert:  Dan replied 10 months ago.

Did they give you a code number? Mass air sensor would not affect the traction control, autozones scan tool will not be able to get the codes from the trac control system. You need a shop quality scan tool for this. The most common problem for traction control problems is wheel speed sensor problems.

Code was P0101. Both lights came on at the same time...engine and traction control. When I replaced the MAF a 2 months ago it was the same issue and was resolved when MAF was replaced.
