Canister Purge Solenoid: Description and Operation
Solenoid Pack
Purpose
Powertrain Control Module (PCM) controls EVAP Canister purge through the solenoid ground circuit.
Operation
PCM controls solenoid by applying and removing solenoid ground.
^ During warm-up and for a set period after hot starts, PCM ENERGIZES solenoid, preventing EVAP Canister purge.
^ When engine warms-up and time delay has elapsed, solenoid is DE-ENERGIZED, allowing EVAP Canister purge.
^ Purge solenoid also DE-ENERGIZED (allowing purge), under certain idle conditions to maintain fuel delivery calibration.
