Canister Purge Solenoid: Description and Operation
A shut-off solenoid is installed on the top of the carbon canister. When the engine is shut-off, the solenoid is de-energized and closes off the purge
line between the carbon canister and intake air boot. This will prevent fuel vapors from collecting in the engine's air intake tract and possibly
causing a hot start problem.
When the engine is started, the fuel injection control unit will switch on the solenoid. The solenoid will open and allow the fuel vapors to be
purged from the canister via the restrictor in the intake air boot elbow.
