Nissan 14935-JF00B Valve Assembly - Control

You can Select Your Vehicle to check if 14935-JF00B fits your vehicle.

On prime of the engine is where the solenoid valve is fixed. Two hoses from the solenoid valve should be removed. Solenoid valve's electrical connector has to be disconnected. After that, remove mounting bolts and then remove valve. Install in reverse order of removal. The vehicle must be locked onto jack stands, jacked up and supported in a safe manner. Remove the mounting nut by disconnecting canister. Open hoses from canister. Take out the EVAP control system pressure sensor by pulling it out from the canister. When changing sensor, change O-ring first. EVAP Canister Vent Control Valve is released by turning counterclockwise and pulling upward slightly. However, before replacing the vent valve, replace O-ring first. Installation is reverse of removal.

Remove the engine cover, then disconnect pipes from the solenoid valve. Discard the electrical connection between the solenoid valve and its wires. Remove any screws attaching it to its mounting then take the valve out. Re-installation is done in a reverse order as dismantling was done. With rear of vehicle raised, support it with jack stands under secure conditions. The rock guard that shields the EVAP canister should be removed. Unplug electrical connector and hoses from canister. Mounting bolts which hold the canister (EVAP canister mounting bolts) are to be removed from its location before detaching it completely. In order to get it out, pull off EVAP control system pressure sensor from inside the canister. Prior to sensor installation, replace its O-ring first. Twist counter clockwise to remove EVAP canister vent control valve. Replace an O-ring before you replace a valve this time round. Installation is not different from uninstallation.

To replace the purge control solenoid valve one has to first loosen the bolts and remove the engine cover, then disconnect the hoses from the valve, which consists of electrical connector, two hoses, two mounting nuts. After that, unbend the electrical connector and unscrew the mounting nuts to demount the valve from the bracket and mounting while the procedure of mounting inverses the process. For a canister that is situated under the vehicle, near the right rear wheel, you need to lift the car and place it on secure jackstands. First, the EVAP canister protector has to be taken off by unscrewing the shield fasteners Next all the connectors have to be disconnected including electrical connectors of the control pressure sensor and the vent control valve, the canister purge hose, the fuel tank EVAP breather hose, and the vent control valve hose have to be removed. Take out the canister retaining bolts and then take out the EVAP canister; to install simply reverse the process. The pressure sensor which is part of the EVAP control system is connected to the canister with its base; to release it, the individual merely has to pull out the whole sensor whereas the vent control valve is loosened by turning the valve counter clockwise and then pulled out. Clean the O-ring in acetone if needed, and look for splits or damage; replace in needed because installation is the opposite procedure of removal.

The components of the crankcase emission control system require regular checks to ensure the hoses are clear and undamaged, with attention to their fitted positions during removal. For evaporative emission control, if a fault is suspected, hoses should be disconnected from the charcoal canister and purge control valve to check for blockages. Renewal of the charcoal canister, located under the car near the fuel tank, involves jacking up the rear, disconnecting hoses, removing the canister, and refitting in reverse order. The purge control solenoid valve, found in the rear right-hand side of the engine compartment for 1.2 litre models or on the inlet manifold for 1.6 litre models, requires disconnection of the wiring and hoses before removal and reinstallation. Exhaust emission control involves checking the catalytic converter's performance with an exhaust gas analyser; if CO levels are high, a Nissan dealer should inspect the fuel injection and ignition systems. Renewal of the catalytic converter and oxygen sensors, which are sensitive and should not be dropped or cleaned, involves jacking up the vehicle, disconnecting wiring, unscrewing the sensor, and applying high-temperature grease before reinstallation, ensuring proper routing of the wiring to avoid contact with hot components.

The hoses from the purge control solenoid valve and the electrical connector from the valve.

The EVAP canister is located underneath the vehicle, to the rear of the fuel tank.

To remove the engine cover, you need to disconnect the electrical connector from the purge control solenoid valve, loosen the hose clamps and disconnect the hoses from the purge control solenoid valve. Then, remove the purge control valve mounting fasteners and remove the purge valve from its mounting bracket.

To install the solenoid valve in V6 models, follow the reverse of the removal process. Begin by attaching the solenoid valve, securing it with the mounting bolts, reconnecting the electrical connector, and reattaching the two hoses.

Nissan does not sell connector, they only sell complete wire harnesses.
