DTC P1415 or P1416
Circuit Description
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 and the AIR solenoid valve. Engine vacuum is applied to the AIR shut-off valve when the AIR solenoid is energized. The engine vacuum opens the AIR shut-off valve which allows air to flow to the exhaust manifolds.
The PCM monitors the heated oxygen sensor (H02S) voltages to diagnose the AIR system.
During the AIR test, the PCM activates the AIR pump during Closed Loop operation. When the AIR system is activated, the PCM monitors the H02S voltages and short term fuel trim values for both banks of the engine. If the AIR system is operating properly, the H02S voltages should go low and the short term fuel trim should go high.
If the PCM determines that the H02S voltages for both banks did not respond as expected during the tests, the diagnostic trouble code (DTC) P0410 sets. If only one sensor responded, the PCM sets either a DTC P1415 or P1416 to indicate on which bank the AIR system is inoperative
