The secondary air injection system is located under the car on the drivers side at about the transmission. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Cheers

Hi, My Envoy has a defective secondary air injection - can I purchase parts and repair myself and if so, how do I do it?

yes you can purchase the parts but make sure you install a new air diverter valve also.

check valve is around $140.00 I dont show a listing for the diverter, call your local dealer and they can help you with that part. Yes you can do it yourself, just need afew wrenches and some WD-40 for the valve

what was the code?was it a p0410?start with the air pump check valve on the side of the block,they get water in them and get rust and corrosion in them. check that first.
