410 means the computer is not seeing the 02 sensors go lean when the air injection pump is activated. The pump may not be coming on when commanded or the hoses or check valves in the system may be inoperative or not connected at all. Very common problems are after a heavy rain storm that gets into the air intake for the pump and shorts and blows a fuse for the system.
