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.

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

Ive got a question regarding the secondary air injection solenoid valve. I had my check engine light go on and it came back as a secondary air injection solenoid valve. Any help on where I could pick one up and where is it located on the vehicle? Any feedback would be excellent!

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.
