Mazda CX-5 Service & Repair Manual: Pressure Control Valve [Skyactiv G 2.0]
U.S.A. And CANADA
Purpose, function
-
Prevents fuel tank damage by suppressing the vacuum applied to the fuel tank while the purge solenoid valve is open.
-
Suppresses the vacuum applied from the charcoal canister side to the fuel tank.
Construction
-
Integrated with the evaporative hose and installed to the side of the fuel tank.
-
There is an orifice inside the pressure control valve.
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.
