Unusual CEL... for a newage 03 WRX IMHO
I'd try and "borrow" a known working MAF and try that first
.........only because The Lambda sensor and the fuel pump fail less often (just )
Tricky one

I dont want to sound offensive but do you have a cheap induction kit on it by any chance?
I had exactly the same problem on my bugeye, I changed the MAF sensor and but the original filter housing on and it was fine again

possibly will have to reset but on the other hand a 5 min drive might put it right.
Now that you've said that I'm positive its the induction kit, you should have no probs after. If you want an induction kit I have found the Perrin one works fine without any CEL issues.
Let me know how it goes
