The EVAP canister vent control valve is located on the EVAP canister and is used to seal the canister vent. This solenoid responds to signals from the ECM. When the ECM sends an on signal, the coil in the solenoid valve is energized. A plunger will then move to seal the canister vent. The ability to seal the vent is a necessary part of the diagnosis algorithms for other evaporative loss system components.

Don't forget to wear safety glasses! The EVAP canister purge control volume control valve is operated by a step motor for control of flow rate of fuel vapor from EVAP canister. Each time the valve opens or closes to change the flow rate, an on pulse is issued. When no change in the flow rate is needed, the valve remains at a certain opening, hence no pulse signal output is issued. Note: This video is being performed by an experienced tech.
