SECONDARY AIR PUMP. The secondary air pump is a component of the vehicle emission control system designed to supply additional air into the exhaust manifold or exhaust system in order to promote oxidation of unburned hydrocarbons and reduce harmful emissions. The system is primarily used in gasoline engines and operates during cold engine start when the catalytic converter has not yet reached operating temperature. By injecting additional oxygen into the exhaust stream the pump helps accelerate catalytic converter warm-up and improves emission control efficiency. The unit typically consists of an electric motor driven compressor with an internal impeller, sealed housing and electrical connectors. It operates together with the engine control unit, secondary air valves and emission monitoring sensors. Failure symptoms may include increased emissions, diagnostic fault codes, unusual noise or vibration from the pump area. Our catalog includes genuine OEM secondary air pumps, quality aftermarket replacements and inspected used units without housing or impeller damage. Used parts are tested for motor operation, structural integrity and electrical connector condition. Selection is based on VIN number, engine type and emission system configuration. Proper replacement ensures correct emission control system operation.
