Canister Purge Volume Control Valve: Description and Operation

COMPONENT PARTS

EVAP Canister Purge Volume Control Solenoid Valve






The EVAP canister purge volume control solenoid valve uses a ON/
OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.
