Default CEL P0411

Hello,
I was finally able to get the CEL code from discount auto parts. They were able to pull the P0411 code 2 times. If i'm not wrong it is something about incorrect air flow. Is this something i can fix my self or do I have to take it to a Honda dealer. Help appreciated. Thanks

If all you did was wash the engine bay, then I suspect that in the process, you knocked off one of the vacuum lines for the secondary air injection system. Go to this thread and trace everything till you find where the system has been disconnected:

you the man xviper, i just went outside right now and one of the vacuum hoses was disconnected. No more bright CEL while i'm drive. You just saved me some money as I was taking my car to the Honda dealer.

I'm glad this helped you out. It probably saved you at least an hour's dealer service rates. You might consider putting 20 bucks of that into a membership here if you considered that this thread was worth it to you.

Another great idea from the x-man!! Some of us pay it forward, some pay it back.
