Default ? About some Fault Codes

My codes are p0418 and p0412 something to do with the electrical circuit for relay "A" of the secondary air injection system and the electrical circuit for switching valve "A" of the secondary air injection system? I am maybe guessing MAF sensor?

It has nothing to do with the MAF sensor. It is going to be a PCM or AIR relay problem. Try replacing the AIR pump relay as a quick shotgun fix, you may get lucky.

Well I replaced relay and erased the code then it ended up popping up again. Then I noticed that there is also a air pump fuse. Checked it, it was burned then I replaced it and deleted the codes again. So far so good, been two days! No more check engine light. Thanx for pointing me in the right direction!
