What Does the P1416 Code Mean?

A Secondary Air Injection (AIR) pump is used on this vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) supplies a ground to the AIR pump relay, which energizes the AIR pump. The PCM monitors the HO2S voltages to diagnose the AIR system. During the AIR test, the PCM activates the AIR pump during closed loop operation. When the AIR is activated, the PCM monitors the HO2S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the HO2S voltages should go low and the short term fuel trim should go high.
