Air Injection Pump: Description and Operation

Electric Air Pump:

PURPOSE
The Electric Air Pump (EAP) provides pressurized air to the Secondary Air Injection (AIR) system.

OPERATION
The EAP functions independently of rpm and is controlled by the PCM. The EAP is only used for short periods of time. Delivery of air is dependent on the amount of system backpressure and system voltage. The inlet system of the pump incorporates a non-serviceable filter and Splash Cap which helps to guard against dirt and water.
