Default Code thrown: PO140

My 1996 Monte Carlo Z34 3.4L DOHC is throwing this code: P0140 Secondary Air Injection System Malfunction. I went OBD-codes to see what it contains. This is a link to what I got: http://www.obd-codes.com/p0410

I am curious as to how I can go about checking this. I haven't checked the fuse yet, which is on my list to do.

Go to AutoZone and get them to Plug-in the Reader and get the Codes and any Pending. THEN ... Go inside and Plug-in the Code reader to the Printer. Get the FULL Diagnostic Read-out with ... WITH >>> TROUBLESHOOTING and Repair recommendations. The Print-out will tell you what to do and in WHAT ORDER. Follow the instructions and you'll see if its something thats a Fuse, easy fix or something requiring new parts.

I didn't know that autozone did that because I am used to advanced auto. My advanced only did the computer scan to tell you what the code is. I'll have to do the autozone.
