Odd CEL issue

[Aceventura9586]

Well it's been a while since posting anything but I haven't changed anything on the car and haven't had anything going on. But now I do. As we all know the vapor leak system will pop on if you haven't tightened the gas cap after recently getting gas. Well I tried resolving that, after my engine light and TSC Off light came on randomly. I remembered getting gas recently so I tightened the cap and after some driving it turned off. But now it's turning on at random times, and also clearing itself. Does this sound like an 02 sensor about to die to anybody? I'm just not used to the light going off and on like a damn traffic light. And am I correct in assuming that the TSC turns off automatically to prevent any damage to that system?

Scan it for codes. Wether the light is on or not all previous codes will
Be stored as history codes. Might even be under Pending codes as well
