Electric AIR Pump (EAP) provides pressurized air to secondary air injection system. EAP functions independently of RPM and is controlled by PCM. EAP is used for short periods of time. Delivery of air is dependent on amount of system backpressure and system voltage. Inlet system of EAP incorporates a non-serviceable filter and splash cap which helps to guard against dirt and water.
