Ford 9U5Z-9F945-C Vent Control Solenoid

EVAP stands for Evaporative Emission Control and EVAP system is responsible for succumbing the fuel vapors and then emitting it into the intake manifold once the car engine is running so as to mix with the arriving air fuel mixture. The various parts of the EVAP system are the EVAP canister, the vent solenoid, the filter tube, the dust separator and the canister purge valve, with the canister together with related components situated within the vehicle above the spare tire while the purge valve is situated in the engine compartment adjacent to the brake fluid reservoir. Other accessories include Fuel Tank Pressure (FTP) sensor, Fuel Limit Vent Valve (FLW) assembly, check valve for fuel filler pipe, cap for filler neck as well as the EVAP system check. Overfilling and vapor escape is eliminated by the use of fuel filler neck cap and the FLW assembly has the responsibility of controlling the flow of fuel vapor and prohibiting the entry of liquid fuel into the EVAP lines in a case of a vehicle rollover. The FTP sensor triggers the purge valve where tank pressure is high, it also measures vacuum levels during testing. The EVAP system monitor in a vehicle will perform a 'running loss system leak test' in which the engine is started and tested for large leaks, before running the test to note the rate of decay as an indicator of minor leaks. For component replacement, there are the EVAP canister purge valve which at the removal, entails disconnecting the electrical connector and quick-connect couplings as well as releasing it from the mounting bracket. The EVAP canister assembly comprised different parts, and to check or replace any component, the negative terminal of the battery has to be disconnected, car has to be raised and some hoses and mounting bolts have to be disconnected or removed, and after installation, all the parts are refitted in the reverse order.

To replace the EVAP canister purge valve, disconnect the negative battery terminal and remove the engine cover. Disconnect the electrical connector and EVAP line from the purge valve. Remove the mounting stud bolts or bracket nuts and remove the assembly. To replace the EVAP canister, disconnect the negative battery terminal and raise the vehicle. Remove the splash shield fasteners and shield. Lower the rear differential assembly and subframe. Disconnect the electrical connector and vapor hose from the EVAP canister vent solenoid dust separator. Remove the mounting fasteners and remove the canister. To replace the EVAP canister vent solenoid and dust separator assembly, remove the EVAP canister and the heat shield. Disconnect the vapor hose and electrical connector from the vent solenoid. Rotate the vent solenoid clockwise and remove it.

When the EVAP system works, it holds back fuel vapor gases that aren't burned in the engine from entering the air we breathe. When it's warm outside, fuel vapors in the tank push up against the sealing cap, and when the pressure hits its limit, the fuel vapor vent valve lets these vapors escape in a controlled way down to the EVAP canister for temporary storage before being burned up while the car is running normally. The PCM first opens the canister purge valve when it detects certain circumstances, and then pulls fuel vapors from the canister into the engine's intake system. The EVAP canister, found under the vehicle against the left side, uses activated carbon to store fuel vapors without needing any upkeep. Along with the check valve and dust separator, the canister vent solenoid makes up the system together. The fuel tank pressure sensor senses the pressure inside the tank and tells the PCM what the reading is when it does an OBD-II leak test. The fuel vapor vent valve helps vapors enter the EVAP system, while the fuel vapor control valve keeps liquid fuel from reaching the canister when we fuel up. The canister vent solenoid stays open to let air through, but blocks the system during checks. The EVAP check valve lets out air from the tank during refueling. The PCM tells the canister purge valve when to let vapor move into the intake manifold. Problems with the EVAP system show themselves when you smell fuel, your car has trouble staying running, and pulls to one side while you drive, all caused by different system components going wrong. We can find out if fuel vapor pressure is too high by taking off the gas cap and listening to any air pressure that releases. Replacing the PCM needs us to turn off the battery, take off the parts that must be handled, then put and wire the PCM back in correctly to make it work well.

Disconnect the cable from the negative battery terminal and raise the vehicle securely on jackstands. Remove the splash shield fasteners and shield, if equipped. For 2015 and later models, lower the rear differential assembly and subframe. Disconnect the electrical connector and vapor hose from the EVAP canister vent solenoid dust separator. Disconnect the two EVAP line quick-connect fittings from the canister. Remove the mounting fasteners and remove the canister. Installation is the reverse of removal.

Disconnect the cable from the negative terminal of the battery.

On V6 models, remove the lower cowl trim panel. On 1.5L models, remove the air filter housing outlet duct. Disconnect the electrical connector from the canister purge valve. Disconnect the EVAP line quick connect fittings. Remove the purge valve and mounting bracket as a single assembly, then depress the lock tab and slide the purge valve off the mounting bracket. Installation is the reverse of removal.

The purge valve is located at the right-hand rear of the engine compartment.

Disconnect the electrical connector from the vent solenoid by depressing the release tab and pulling off the connector.
