traction control lite comes on after beep, lurch, temp gauge maxes out for a sec

may be two different size tires on back axle confusing the traction control system,i had similar problem while using the temporary spare tire on back-also a bad ignition switch could have something to do with it next time it happens,slightly wiggle your keyback and forth and side to side-good luck.

Having same problem but car will stall but alwAys restarts, replaced temp sensors,someone please help
