Evaporative Emission (EVAP) Control Diagram
The EVAP controls minimize the a m o u n t of fuel vapor escaping to the atmosphere. Vapor f r o m the fuel tank is
t e m p o r a r i l y stored in the EVAP canister until it can be purged f r o m the canister into the engine and burned.
• The EVAP canister is purged by d r a w i n g fresh air t h r o u g h it and into a port on the intake m a n i f o l d .
The purging v a c u u m is controlled by the EVAP canister purge valve, w h i c h operates whenever engine coolant
temperature is above 140 °F (60 °C).
• During refueling, the fuel tank vapor control valve opens w i t h the pressure in the fuel tank, and feeds the fuel vapor
to the EVAP canister.
