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.
