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 mechanically opens and closes in accordance with the difference between the tank pressure and atmospheric air pressure, and the tank pressure and canister pressure.
During the diagnosis, the valve is forcibly opened by setting the solenoid to ON.
