Exhaust Emission Control System Description

The exhaust emission control system is composed of the PAIR system, HO2 sensor, three-way catalyst system and
ISC 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, which is controlled according to the signals from TPS, ECTS,
IATS, IAPS and CKPS. The ISC valve adjusts the bypass air volume of the throttle body to control engine idling speed
with various sensor signals by varying engine running conditions and the idling control contributes to reduce exhaust
emission level.
