I have a 2019, GMC Sierra Duramax, with low miles. The check engine light has recently come on and has thrown the same code twice after being deleted. I have a pic for reference, does anybody have any ideas where I could start to get this one fixed? Thanks, Cody

Both of these codes came back after being cleared?

The bottom code came back the top one did not.

If these are a permanent code, dont you have to 'fix' the problem and reset?
