Description

DESCRIPTION





This vehicle is equipped with a secondary air injection system. The Secondary air injection system consists of an Air Pump that forces air into the exhaust ports of the cylinder head to reduce the emissions during engine warm-up. The air injected into the exhaust will cause the catalytic converters to heat up more quickly. This will improve the emission levels during a cold start. The Air Pump Switchover System incorporates an Air Pump (1) with two Air Pump Switchover Valves (2 and 3), an Air Pump Switchover Solenoid (5), an Air Pump Relay (4), and the PCM.

The Air Pump is mounted to the front of the engine. The Air Pump Switchover valves (2 and 3) are located at the front, top of the engine, mounted just in front of the left and right cylinder covers. The Air Pump Switchover Solenoid (5) is mounted on the right front of the engine, next to the air pump (1).
