What is the role of the Secondary Air Injection system in reducing emissions during cold starts?

The Secondary Air Injection system reduces emissions during cold starts. It includes an AIR pump, shut-off valve, and pressure sensor. Filtered air goes from the engine's air filter housing to the pump, then to the shut-off/pressure-sensor assembly on the exhaust manifold. A scan tool is recommended for a thorough inspection. The AIR solenoid/shut-off/pressure sensor should be replaced as a complete assembly.

Chevrolet Cobalt Secondary Air Injection Pump

Chevrolet Cobalt has a device called Secondary Air Injection Pump, or the Air Injection Reactor (AIR) system is used to control Hydrocarbons (HC) and Carbon Monoxide (CO) emissions, by pumping fresh air into the exhaust system. Components of this system are an electric or belt-driven air pump, an air control valve, a vacuum switch, a diverter valve and one-way check values and hoses and tubes. During deceleration back fires are avoided while the diverter valve directs the compressed air to atmosphere, one way check valves to avoid damage to the air pump by the hot exhaust gases. Diagnostic of the Secondary Air Injection Pump used by Chevrolet Cobalt involve checking of the hoses and valves for damages and checking for Diagnostic Trouble Code escalated by the Engine Control Module in cases where they are triggered.
