2000 GMC Truck DTC P1416: Secondary Air Injection System Fault - How to Diagnose and Fix

Model: 2000 GMC Fault Code: P1416 Posted: 2012-06-10 20:13

My 2000 GMC truck is showing a DTC P1416 emission control code on the OBD-II scanner. The code indicates a fault in the Secondary Air Injection (AIR) System for Bank 2, which is part of the manufacturer-controlled auxiliary emission control system. I've turned off the check engine light using the scanner, but I'm unable to locate any official documentation or troubleshooting guides for this specific code. Can anyone confirm what P1416 means in a 2000 GMC truck and provide guidance on how to diagnose and repair the issue? The code is consistently reported by the scanner, so it appears legitimate.
