Canister Purge Solenoid: Description and Operation

In this evaporative emission (EVAP) control system, purge flow occurs during non-closed throttle conditions. Purge volume is related to air intake
volume. Under normal purge conditions (non-closed throttle), the EVAP canister purge volume control solenoid valve is open to admit purge flow. Purge
flow exposes the EVAP control system pressure sensor to intake manifold vacuum.
