My ‘15 tc check engine light came on this morning. I currently have 112k miles on it, always on schedule with maintenance at the Toyota dealer. Any guesses on what it can possibly be?

I can’t take it to the dealership until the weekend 😭

The stressors in my life are high and this just blew the top off.

 

Any guesses...yep, you have an issue and, based upon the minimal detail provided, that's about as good as it's going to get.

Take your car by an AutoZone or O'Reilly's, they should be able to at least read the code(s) that caused your CEL.
