Pressure Control Solenoid Valve
WARNING: This page is about a different variant/trim than selected.
PCV controls the fuel tank pressure to be equal to the atmospheric air pressure.
Normally, the solenoid is set to OFF. And the valve opens and closes mechanically in accordance with the pressure difference between tank and atmospheric air, or tank and canister.
During the diagnosis, the valve is forcibly opened by setting the solenoid to ON.
