Canister Purge Solenoid: Description and Operation
Auxiliary Purge Control Valve
Auxiliary Purge Control Valve
PURPOSE
Allows the canister to be purged under boost conditions.
LOCATION
In-line between the canister and the air intake boot.
OPERATION
When intake manifold pressure exceeds a preset level, the auxillary purge solenoid opens a vacuum line between the canister and the intake
resonator, before the turbocharger. This allows purging of the canister, but prevents any damage that would be caused if boost pressure was
supplied to the canister.
