Evaporative Emission (EVAP) Control System
Refer to the System Diagram to see the functional layout of the system.
EVAP Canister
The EVAP canister temporarily stores fuel vapor from the fuel tank until it can be purged from the EVAP canister into the engine and burned.
EVAP Canister Purge Valve
When the engine coolant temperature is below 65 °C (149 °F), the ECM/PCM turns off the EVAP canister purge valve which cuts vacuum to the EVAP canister.
