The first thing I would do is check the engine oil level and the engine coolant level when the engine is cold. If the engine oil is over filled it can cause white smoke, also if you have a blown head gasket the coolant will be low and the white smoke will have a sweet/pungent smell.
P2279-7A - Intake Air System Leak
P06DA00 - Engine Oil Pressure Control Circuit Performance
Also, remove the oil fill cap on the engine to see if it has a brown/whitish goo, this will be a sign the engine coolant is leaking inside the engine. Please go over this guide for more information.
