same thing happened to me this summer. ended up having to replace the engine. vct went and cam phasers were out of whack because the timing chain plastic guides broke and were chewed up into the engine and clogging sensors and oil wells thus loosing oil pressure.

what kind of oil and filter
and check the oil level make sure is it not too low or high because it can cause it to throw those codes without the oil light on
