Secondary Air Injection System
I had the check engine light on for an O2 sensor...pulled out the old, put in the new, light went out and I was pretty happy. 
Then the check engine light came on again.
I pulled the code and ended up with this: DTC P0410 Secondary Air Injection (AIR) System.
Anybody know what I need to do to fix this and turn off that orange light?

I went through this and after replacing the AIR pump twice and both check valves and spent about $600 and still had the light come on. I then took the advice that I hope you will take and find a good tuner. Have the tuner change the parameters that cause the system to cycle and the problem goes away. The AIR does nothing for performance and is only there to satisfy EPA emissions by adding "fresh air" to the exhaust prior to the CATs heating up. Save yourself time and money and have this "tuned" out. Good Luck.
