Had these codes pop up today, but they went away about 15 min later, anyone have these codes?
My JB4 firmware is up to date and I have the EWG cable running map 3 car is stock otherwise.

Quick update for anyone that may run into similar issues with the JB4, if you do add an EWG cable disconnect your battery before doing it.
I went back and simply disconnected my battery since I was in a rush during the initial install and forgot that step which somehow that caused the codes since I left the obd2 plugged in.
