Air System (If Equipped)

AIR System (If Equipped):

The PCM turns ON the AIR system during startup when engine coolant temperature is between 10°C (50°F) and 110°C (230°F). When ECT is above 80°C (176°F) at start up, AIR system operation will be delayed approximately 65 seconds. The AIR pump will operate for approximately 60 seconds. When the PCM turns the AIR pump OFF, it also de-energizes the AIR Solenoid Valve. The closed AIR Solenoid Valve prevents air from being drawn into the exhaust and also prevents the backflow of exhaust into the AIR System.

Refer to DTC P0410 Secondary Air Injection (AIR) System for enabling and disabling criteria.
