The emission control system is divided into the following subsystems which are controlled and coordinated by the ME control unit:

Closed-loop mixture control
Two-sensor control
O₂ sensor heater
Exhaust gas recirculation
TWC heating.

The task of the emission control system is to reduce the exhaust emissions of:

nitrogen oxides (NO_X )
hydrocarbon (HC)
carbon monoxide (CO).
