Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Have you tried to clear out these codes then operate the vehicle to see which codes come back again?

Is the engine running poorly with these codes at all?

Has anything been checked,tested or replaced to try and locate or repair this issue here at all?

Let me know so we can continue,thanks Pete.
