Hello I'm Paul and I will help you with an Answer to your Question

 

this code is for the secondary air system part of the emissions system

 

most often a valve and or air pump fails in the secondary air system.

 

you will need to have the system diagnosed to see which part has failed

 

I am attaching the test information

 

click here to view test info on p0411

this type of diagnostic would run around $100 at a shop to determine which parts have failed

 

Remember to rate my answer positive so I get credit for my help.

 

If you need more help just log in to the site and reply the question will remain for follow up.
