Anybody knows how to fix this code? Which part I need to check? My car is Dodge Intrepid '02.

 

P0411 Secondary Air Injection System Incorrect Flow Detected


if it is a second gen and that is the error code, then that is the problem. i don't know how to fix it, but maybe this helped you narrow down what the problem was.

 

To nickoman01,

Thank you for your help. Anyway, My car has error 441, "Evaporative purge flow system not working properly". I have checked a gas cab, but it's fine. There is no hissing noise from the hose also. I am really totally lost now to find the cause of this problem.
