The emission control system is divided into the following subsystems which are controlled and coordinated by the ME control unit:
^ Lambda control
^ Two-sensor control
^ O2 sensor heater
^ TWC heating up
^ Secondary air injection

The task of the emission control system is to reduce the exhaust emissions of:
^ nitrogen oxides (NOX)
^ hydrocarbon (HC)
^ carbon monoxide (CO)
