I Am getting a Secondary Air Induction code on my 01 blazer 4x4 and i was wondering what that is as i cannot find it in the chilton manual?........btw first post and this forum is great!

 

THIS THREAD should help you out on what the AIR system is. The pump is located up under the radiator near the passenger side frame rail. Most common failure is due to water injestion, corroding the pump. THIS THREAD should shed some light on the situation as well.

What was the specific code?
