Default Check engine light just came on... any ideas?

It just popped on as I was driving. The car drives fine, I didn't notice any difference. My temp was normal and my boost gauge showed normal boost (14-16 psi). I did however hear a hissing sound when I opened the hood. I'm thinking it's a vacuum hose but wouldn't that affect my boost readings?

It's definitely not the gas cap... I always make it click a few times when I tighten it.

TIA!
Pete

Default Unfortunately not.

I had a mechanic do the work and I wasn't able to be there to see which hose it was this time. All I got was "air injection hose" They also replaced my water pump, which was actively leaking, so is possible that could have been the reason for the light as well.
