EXHAUST EMISSION CONTROL SYSTEM (PAIR SYSTEM)

The exhaust emission control system is composed of the PAIR system, exhaust control system and

three-way catalyst system. The fresh air is drawn into the exhaust port through the PAIR control solenoid

valve and PAIR reed valve. The PAIR control solenoid valve is operated by the ECM, and the fresh air flow

is controlled according to the TPS, ECTS, IATS, IAPS and CKPS. The exhaust gas flow is performed by the

exhaust control valve actuator which is controlled by the ECM by changing the exhaust control valve angle.
