This is how to fix your check engine code P0410 on the ODB2 scanner for the secondary air pump. There are some great videos about how to check the fuse, fuse relay, secondary air pump and a common issue is the vacuum lines. My relay was good and so was my fuse, and the pump worked when connected to the battery. I noticed a crack in my vacuum line and put Permatex gasket sealer on it but the P0410 code would not erase. The Autozone crappy borrow for free scanner is a joke. Buy BlueDriver ODB2 scanner or any good advanced one that has realtime drive cycle infromation. www.amazon.com/dp/B00652G4TS?... I also replaced my bad vacuum lines since I didnt know about the drive cycle yet. You can buy the vacuum lines on FCP Euro.
