Default error code question

I have a 2020 c8 HTC with AWE Touring Exhaust.

A few months after installation i got an error code. AWE said it was probably a bad valve simulator. We replaced the simulators and the code went away.

after a few months the error code is back. I called On star and they said it was P31CF and P31D1.

Any Ideas?

Nothing turns up with a Google search, perhaps you can have your codes read at Autozone etc. just to verify ?

Nothing in the 2020 Corvette Service Manual for either code.
