Fuel and Emissions Systems
System Description (cont'd)
Evaporative Emission (EVAP) Control Diagram
The EVAP controls minimize the amount of fuel vapor escaping to the atmosphere. Vapor from the fuel tank is
temporarily stored in the EVAP 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 140 °F (60 °C).
