Canister Purge Solenoid: Description and Operation
Evaporative Emission Control System
The Purge Cut-off Solenoid Valve, mounted inside of the control box, is used to control vacuum to the EVAP purge control valve. Canister purging is
accomplished by drawing fresh air through the canister and into a port on the throttle body. The ported vacuum is controlled by the purge control
diaphragm valve which is controlled by the Purge Cut-off Solenoid Valve.
NOTE: 5 seconds after engine start, the purge cut-off solenoid valve remains off until coolant temperature warms above 167°F (75°C).
