Canister Purge Solenoid: Description and Operation
EVAP Canister Purge Valve
When energized, the evaporative Canister Purge Valve allows the fuel vapor to flow from the EVAP canister to the engine. The normally closed valve is
pulse width modulated by the Control Module in order to precisely control the vapor flow. The valve opens during the Enhanced Evaporative Diagnostic
Test in order to create a vacuum in the fuel tank and then closed in order to seal the system.
