Secondary Air Injection Pump failures are almost always caused by corrosion that derives from water or moisture in exhaust gas that finds its way into the pump enclosure. When you meet engine stalling, low idle, weak acceleration, check engine light, failed emissions test, it means that the air pump has been damaged.In order to allow your vehicle to emit normal carbon emissions, you need to replace the pump in time.
Secondary Air System is designed for exhaust gas reprocessing in the engine warm-up phase. Secondary air injection pump is responsible for lowering the number of carbon emissions that come out of the tailpipe of a vehicle. It can reduce carbon emissions and hydrocarbon pollutants by pumping fresh air from outside into the exhaust stream so unburned fuel can be burned. If there is ever a problem, more hydrocarbon pollutants will be in the fumes which come out of your tailpipe.
