I have a 2002 cadilliac deville with a check engine light problem. I had it checked and the ODB code was P0410 . The fuse for the secondary air pump was blown which indicated a bad or sezied pump. I had the secondary air pump replaced and drove the car 160 miles. I assumed after driving 160 miles that the pump resolved the issue. The car sat overnight when I started the car in the morning my check engine came on again. I checked the ODB codes and again received a P0410 indicating a secondary pump issue. Anyone out have the ame problem or solution before I start pumping more money into this issue. Thanks

 

Check your wiring, the fuse blew for a reason maybe other than a bad pump. I'm getting that code on my O3. It just started

 

you may also want to test the pump ...
