P0441

DTC PO441 - Evaporative Emission Control System Incorrect Purge Flow (Only for California spec.)

CIRCUIT DESCRIPTION
To reduce HO emissions, evaporated fuel from the fuel tank is routed through the charcoal canister to the intake manifold for combustion in the cylinders.



The ECM changes the duty signal to the EVAP VSV so that the intake quantity of HC emissions is appropriate for the driving conditions (engine load, engine speed, etc.) after the engine is warmed up.
