Purpose, function

• Prevents fuel tank damage by suppressing the vacuum applied to the fuel tank while the purge solenoid valve is open.

Operation

• When the purge solenoid valve is open, the intake manifold vacuum is applied between the purge solenoid valve and the fuel tank. The pressure control valve suppresses the intake manifold vacuum applied to the fuel tank. In addition, to lead the evaporative gas generated inside the fuel tank to the charcoal canister, it does not suppress the evaporative gas flow (positive pressure) from the fuel tank side.
