P0418 and P0410
Yesterday I was poking around in the fuse box looking for a blown fuse after finding the correct fuse to changed (thanks to lucky at the corvette forum) I got everything working fine. the next time I drive the car I got a check engine light. I read the codes and had 1 code set, P0418, and 2 pending P0410 and P0418. Anybody have any experience with these codes? I can't help to think I loosened something, maybe a ground, while poking around in the fuse box. Any help would be appreciated. Thanks in advance.

sorry about the broken link I'll do better next time. Fuse was good so I erased the codes but don't have a good feeling about their return. I'll find out tomorrow when I drive to work. Keeping my fingers crossed...

It will throw the code regardless if it is an active problem or not. An "H" will come after the code if it has been corrected and is no longer an issue. The light will remain on until you clear the code(s) out.

It's an active one. As a matter of fact I cleared it last night and it came back on this morning as soon as I got out of my drivway. ARGH!! 
Anyone know the first thing about troubleshooting the AIR Pump Relay Control Circuit? If I had a schematic I know I could figure it out...
