Need a little help deciphering these codes

[static667]

Finally got a hold of the guy I know with a code reader. Lets just say that it's a fancy one and I didn't get just straight up numbers. If someone could help out and tell me wft it all means, I'd greatly appreciate it.

I just took a pic of the screen because it was the quickest way to go about it.

Thanks for that, John. I'm still feeling a little tech stupid right now. Could it be the MAF and the secondary air pump? Or do y'all think it's just an O2?

I would change out precats, then go from there.

Thanks, Dane. I'll work out from there.

Bringing this one back from the dead...did replacing your O2 sensors solve the issue? These same two faults came up yesterday on my wife's E39 wagon, so I'm currently in research mode (just past denial mode). Seems like it's easier to test the check valve on the E39 and I'm hoping it's just some tubing gone bad, but curious to hear your solution.
