Canister Purge Solenoid: Description and Operation
Canister Purge (CANP) Solenoid
PURPOSE
The Evaporative Emission (EVAP) canister purge solenoid regulates the amount of evaporative fuel vapors transferred from the EVAP canister
into the intake manifold.
OPERATION
The solenoid operates by an output signal from the Powertrain Control Module (PCM) to open the vacuum passage between the EVAP canister
and intake manifold when purging conditions are met.
The solenoid is normally closed. When the engine is shut off, fuel vapors from the fuel tank flow into the EVAP canister. When the engine is
started, the solenoid opens and purges the vapors into the intake manifold.
