I'm ttt'ing this, because I am having a recurring P0491 and P0492 code that keeps popping up, and I've replaced the secondary air pump and valve. Next up, I'm going to clean out the lines going to the head, since they have to come out in order to do my upper timing cover gaskets, which need to be done anyway. Anyone find any other solutions?

Edit: Dunno if this helps, but the light comes on right AFTER the pump turns off.
