The EVAP controls minimize the amount of fuel vapor escaping to the atmosphere. Vapor from the fuel tank is
temporarily stored in the EVAP control canister until it can be purged from the canister into the engine and burned.

• The EVAP canister is purged by drawing fresh air through it and into a port on the intake manifold. The purging

vacuum is controlled by the EVAP canister purge valve, which operates whenever engine coolant temperature is
above 147°F (64°C).

• When vapor pressure in the fuel tank is higher than the set value of the EVAP two way valve, the valve opens and

regulates the flow of fuel vapor to the EVAP control canister.

• During refueling, the fuel tank vapor control valve opens with the pressure in the fuel tank, and feeds the fuel vapor

to the EVAP control canister.
