Anyone get a P13C2 or P246B code?

I've got both of these codes right now and can't find a consistent definition for the issue. Taking it in next week but curious if anyone's run into this before and what the resolution was.

Did you just switch out the exhaust? Or remove and reinstall the valve controller for any reason? If so, you need a calibration of the exhaust valve operation.

I haven't touched the exhaust or the controller. I've pulled power from the battery before, but that's it.

Not sure then. Both of these codes are associated with the exhaust and have come up when people have switched the exhaust out. Perhaps check to ensure the valve controller hasn't melted. It can be visually verified from the rear.

As a last resort, undue the battery for a few mins. and see if it clears it afterwards or after a little driving in different modes. if not, dealer time...
