13 codes? Cel?

[Unaballer]

Any ideas on where to start? I think it's Connection since there are 13 codes that just popped up today in a 13min drive.

First place I'd start is to clear them all and see what comes back. Sometimes these codes just come out of nowhere and when cleared maybe none, one or two may come back.

Agree, sometimes these codes pop up from no where. Write the codes down and clear, then wait and see what repeats (exactly what a Dealer Technician is supposed to do). Some issues that I have had is connections, they appear solid, when undone they appear clean, I clean with a good quality electrical connection cleaner and apply dielectric silicon grease to the connection, reconnect. That has cleared up a lot of my miscellaneous codes over the years.

Good luck.
