Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
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.
FUNCTIONS WITHIN THE SYSTEM
The EVAP canister purge volume control solenoid valve controls the purge flow of fuel evaporative gas inside the EVAP canister based on the ON/OFF duty signal from the ECM.
INDIVIDUAL FUNCTION WITHIN THE SYSTEM
The EVAP canister purge volume control solenoid valve opens and closes the EVAP line between the EVAP canister and intake manifold.
INDIVIDUAL OPERATION
When the solenoid turns ON/OFF, the EVAP canister purge volume control solenoid valve opens and closes. A longer ON pulse increases the purge flow of fuel evaporative gas passing through the solenoid valve.
Component Location
The EVAP canister purge volume control solenoid valve is installed to the upper of intake manifold.
