Hello,

Your vehicle is equipped with a secondary air injection pump. In order to access it you will have to raise the vehicle as it is mounted on the bottom of the frame rail (see diagram below).

The code P0410 can be triggered due to a bad pump as well as wiring issues or other component failure.

I have attached the trouble shooting steps for the code P0410 below.
Go through this and it can help you determine the issue.

Please let me know if you have any questions.
Thank you.
