Steve Gabriel, live in Cape Girardeau, MO. My wife's vehicle is a 2006 jaguar s type. Engine service light came on, Advanced Auto tested and gave me the code P0491. Secondary air pump bank 2, is this a diy repair?

 

Thanks for the information.
What engine do you have?

Regardless of the engine do this first.
Clear all codes. The auto parts store readers can do this.
Unhook battery to reset things.
Reconnect battery and drive around.
Post back if the code or another one comes back.
