EVAPORATIVE EMISSION CONTROL SYSTEM
DESCRIPTION
The evaporative emission control system consists of the separator, check-and-cut valve, two-way check valve, charcoal canister, purge solenoid valve, engine control module (ECM), and input devices. The amount of evaporative fumes introduced into the engine and burned is controlled by the solenoid valve to correspond to the engine's operating conditions. To maintain best engine performance, the solenoid valve is controlled by the ECM.
Operation
The purge solenoid valve is controlled by duty signals from the ECM to perform purging of the charcoal canister. Purging is done when these conditions are met: (1) After warm-up, (2) Driving in gear, (3) Accelerator pedal depressed (closed throttle position switch OFF), (4) Heated oxygen sensor functioning normally.
