  1. FUNCTION OF MAIN COMPONENTS


    1. The main components of the evaporative emission control system are as follows:

      Component Function
      ECM Controls the purge VSV in accordance with the signals from various sensors, in order to achieve a purge volume that suits the driving conditions.
      Intake Mass Air Flow Meter Sub-assembly Detects the intake air mass.
      Engine Coolant Temperature Sensor Detects the engine coolant temperature.
      Crank Position Sensor Detects the engine speed and performs cylinder identification.
      Purge Vacuum Switching Valve (VSV) Opens in accordance with the signals from the ECM when the system is purging, in order to send the fuel vapor that was adsorbed by the charcoal canister sub-assembly into the intake manifold.
      Charcoal Canister Sub-assembly Contains activated charcoal to adsorb the fuel vapor that is created in the fuel tank assembly.

  2. SYSTEM CONTROL


    1. The ECM controls the purge flow of the evaporative emissions (HC) from the charcoal canister assembly in accordance with engine conditions.
