DTC P0411 - Secondary Air Injection System: Incorrect flow detected

Then check all the vacuum lines against the vacuum map on the VECI label under the hood. It's common for the original plastic lines to get brittle & crack, or they can be melted by an exhaust leak from the crossover tube on V8s, but if you have an I6, it doesn't have that tube.

Check IAC and IAC circuit. Check Secondary Air Injection pump, valve, circuit and hoses for leaks, blockages.

Here can find some diagrams: supermotors.net/registry/media/589993

Hope helps.
