Canister Purge Control Valve: Description and Operation

PURPOSE

The purge check valve prevents evaporative gas from entering the intake manifold and accumulating there. This prevents increased HC emissions
during start-up.

LOCATION

On the canister.

OPERATION

The purge check valve shuts off the purge line when the engine is not operating and when evaporating gas has bypassed the purge canister.
