SOURCE: i got codes p0410 and p1411

You are correct, these are secondary air injection codes. It is under the passenger side intake manifold. There's 3 pieces that can be bad, an electric vacuum switch that's controlled by the ecu, the control valve which is activated by vacuum from the first part and a one-way valve. Also, a vacuum leak in the circuit can cause the same fault code. The one-way valve can be checked simply by blowing into it, it should allow flow in the direction of the arrow but not the other. The vacuum control valve can be tested off the car by applying a vacuum to it, it will make a clear thunking noise when it activates. I'm not sure how to test the electric solenoid, since it is activated by the ECU it would work off of 5 volts. It seems like all 3 pieces would run about $100 so it would not be out of the question to replace all 3 while you're in there. Make sure you orient the electric valves the way they are on the car or you'll get the codes again.
The only sketchy thing about doing it yourself is that you do have to remove the plastic intake manifold on that side, and it is a real PITA to get to. Evidently it is fine to re-use the o-ring gasket that seals it to the aluminum stacks. I hope this helps and good luck!
