Subaru 42084FE010 Valve PURGE

When the engine is on, the Evaporative Emissions Control (EVAP) system's job includes taking in fuel vapors and then letting them go into the intake manifold. Some of its components are fuel tank filler neck cap, fuel cut valve, EVAP canister, drain filter, drain valve, fuel tank pressure sensor, pressure control solenoid valve, shut-off valve, vent valve and purge control solenoid valve. This system works by controlling the fuel tank pressure and retaining vapors in the charcoal canister until they are absorbed by the engine during purging. The EVAP system contains a number of valves that prevent fuel from getting into it when refueling is done. A relief valve within the cap of the filler neck equalizes pressure inside the tank during loading operations. Replacing component parts involves disconnecting battery negative terminal; unplugging electrical connectors; indicating and disconnecting EVAP hoses; removing mounting bolts or nuts before reinstalling items backward. That specific guidance is provided for each model or year.

First of all, to replace the purge control solenoid valve, found under the intake manifold or on a bracket, you can disconnect the negative battery terminal and remove hoses and electrical connectors before reinstallation. The EVAP canister is replaced by disconnecting and reconnecting hoses and connectors. Also, the drain filter and valve, part of the canister in newer models, follow a similar replacement process. Replacing the fuel tank pressure sensor and the vent valve involves removing the fuel tank. The pressure control solenoid valve, situated above the rear axle differential or below the EVAP canister, requires disconnection of its connector and hoses. Installation is the reverse of removal.

A uniform Evaporative Emissions Control (EVAP) system running through Baja, Legacy and Outback models redirects fuel vapors to the intake manifold in operation. The system consists of fuel tank filler neck cap along with other elements such as the fuel cut valve and EVAP canister and drain filter and drain valve and fuel tank pressure sensor and pressure control solenoid valve and shut-off valve and vent valve and purge control solenoid valve which are primarily installed beneath the vehicle. The system controls fuel tank pressure through vapor storage until it ventilates into the intake manifold. The canister provides atmospheric air entry to avoid vacuum development during purging. During operation the diagnostic system monitors system leaks and the valves safeguard the system throughout fueling operations. When an EVAP line develops a kink the fuel tank filler neck cap includes a relief valve so vacuum formation stays prevented. The purge control solenoid valve needs replacement by accessing it under the intake manifold while the EVAP canister requires replacement at the rear of the vehicle. The drain valve together with the drain filter sits above the canister while the fuel tank pressure sensor exists above the inner CV joint boot. The pressure control solenoid valve installation occurs above the rear axle differential while the vent valve placement takes position on top of the fuel tank. To reach the shut valve mechanics need to detach the fuel filler neck pipe because this component is positioned at the top of the assembly.
