General Information

Secondary Air Injection (AIR) System Description:

The purpose of the Secondary Air Injection (AIR) system is to reduce the Hydrocarbon (HC), the Carbon Monoxide (CO), and the Oxides Of Nitrogen (NOx) exhaust emissions by causing any combustible gases in the exhaust to re-burn. This also causes the catalytic converters and the Heated Oxygen Sensors (HO2S) to reach their operating temperatures more quickly, thus Closed Loop operation occurs earlier.
