Purge Control System
The Purge Control Solenoid Valve is spring loaded closed (blocks purge), and opens when grounded by the Engine Controller. The Purge Control Solenoid will be grounded by the Engine Controller after the engine coolant temperature sensor indicates 158°F or higher; and the Air Flow Sensor indicates an intake air flow rate equivalent to 3000 rpm. Once the valve opens manifold vacuum will be applied to the canister purging it of fuel vapors.
