Purge Cut-Off Solenoid: Description and Operation
Purge Cut-Off System Operation
PURPOSE
The solenoid is used by the ECU to control the evaporative emission system.
LOCATION
Located at the rear of the engine compartment, on the firewall.
OPERATION
The ECU applies voltage to the solenoid when engine coolant temperature is below 140°F (60°C). When energized the solenoid cuts vacuum to the
purge control valve which prevents canister purging.
