Liquid Vapor Separator: Description and Operation

2.0L/2.4L If Equipped:

The flow management valve is a part of the On-Board Refueling Vapor Recovery (ORVR) system. This is a plastic valve inline between the fuel tank and the EVAP canister.

The flow management valve meters the flow of fuel vapors to and from the EVAP canister during vehicle run and refueling. Pressure from the tank during refueling opens the main port valve and allows vapors to the EVAP canister. During vehicle run, the vapors are metered through an orifice to the EVAP canister. It also is a liquid separator to keep fuel out of the EVAP canister
