Issue / Concern

My check engine light popped on yesterday with code P0412. I can hear a loud hairdryer-like noise for about a minute when I first start the truck in the morning. It seems to run fine otherwise, but I need to clear this for emissions testing next week.

Checked the fuse for the air pump and it was okay. Inspected the rubber hoses for obvious cracks but everything looks tight.
