Enhanced EVAP System

PURPOSE/OPERATION
- The evaporative emission control system is employed to prevent evaporative fuel from being discharged into ambient atmosphere. This system includes a canister, purge control solenoid valve, fuel cut valve, their connecting lines, etc.
- Gasoline vapor evaporated from the fuel in the fuel tank is introduced into the canister located in the engine compartment through the evaporation line, and is absorbed on activated carbon in it. A fuel cut valve is also incorporated on the tank fuel line.
- The purge control solenoid valve is controlled by the Engine Control Module (ECM) and provides optimal purge control according to the coolant temperature, engine load and vehicle speed. On 2200 All Wheel Drive models the signals from the fuel temperature sensor and fuel level sensor installed in the fuel tank are used for this control.
- A pressure control solenoid valve incorporated in the fuel tank evaporation line controls the pressure/vacuum in the fuel tank according to the pressure/vacuum sensed by the fuel tank pressure sensor.
