DTC P0443 Evaporative Emission Control System Purge Control Valve Circuit: Description
WARNING: This page is about a different variant/trim than selected.
To reduce hydrocarbon emissions, evaporated fuel from the fuel tank is routed through a charcoal canister to the intake manifold for combustion in the cylinders.
The ECM changes the duty signals to the purge VSV so that the intake amount of hydrocarbon emissions is appropriate for the driving conditions (engine load, engine speed, vehicle speed, etc.) after the engine is warmed up.
