The trac off light in my lexus car went on yesterday. There is switch to tutrn it on and off, I tried but didn't work. Does this has anything to do with the spark plugs since I changed them last week or sensors?
I think this is telling you that your traction control system is not working. The car will continue to function just fine. Traction control helps you to avoid skidding or to regain control if you do skid. So it's a good safety feature.
