Evaporative Canister Purge Solenoid

Evaporative Canister Purge Solenoid:

When energized, the evaporative canister purge solenoid 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 closes in order to seal the system.
