Yes ...Once you fix the Problem that set the codes !!
Clearing just the codes ...is not going to fix the problem.
So fix the problem first...

Obviously the problem hasn't been fixed. Permanent codes clear automatically when the problem is fixed. Both codes have the same possible causes.
Leaks or restrictions in the intake air system and charge air cooler (CAC)
Leaks or restrictions in the crankcase ventilation system
Damaged mass air flow (MAF)/intake air temperature (IAT) sensor
Biased MAF/IAT sensor
Damaged exhaust gas recirculation (EGR) valve
I would guess a problem with the crankcase ventilation system.
