False air or vacuum is the cause for these code, and because it is a false air it will also set a MAF (Mass air flow). A vacuum leak is unmetered air that gets pass the MAF. Some of the starting place to look for vacuum leak and this is common , a broken dipstick, , PCV valve, or any crankcase ventilation hose . or even a missing oil cap.
