Infiniti Fx35 Vapor Canister Vent Solenoids

Infiniti Fx35 Vapor canister vent solenoids

Starting at $56.95, AutoBuffy stocks 3 vapor canister vent solenoids from Dorman and Standard Ignition for the Infiniti Fx35. This solenoid controls airflow through the evaporative emission (EVAP) canister, sealing fuel vapors in the system during purge cycles. When it fails, your Infiniti Fx35 will typically trigger a check engine light and fail emissions testing, and you may notice fuel odor or hard starting.

Signs your Infiniti Fx35 needs a new vapor canister vent solenoid

  • Check engine light illuminated with EVAP-related fault codes such as P0446, P0447, or P0448
  • Failed state emissions or OBD-II inspection due to an incomplete or failing EVAP system monitor
  • Noticeable fuel or gasoline odor near the rear of the vehicle or around the fuel tank area
  • Hard starting or extended crank time, especially after the vehicle has been sitting for several hours
  • Poor fuel economy caused by the EVAP system being unable to route fuel vapors back into combustion
  • Fuel tank pressurization or a difficult-to-remove fuel cap, indicating the vent path is stuck closed

Which vapor canister vent solenoid should you buy for your Infiniti Fx35?

The main buying decision comes down to OE-equivalent fit versus upgraded build quality, and whether the solenoid is sold as a standalone unit or as part of a kit with the connector pigtail included. Confirm the solenoid's electrical connector style and mounting configuration match your Infiniti Fx35's specific EVAP canister location before ordering.

Replacing the vapor canister vent solenoid on a Infiniti Fx35

Easy⏱ 30–60 minutesOBD-II scanner (to read and clear fault codes)Flathead and Phillips screwdriversTrim panel removal tool or small pry barNeedle-nose pliers (for hose clamp removal)Multimeter (for pre-replacement testing)

The vapor canister vent solenoid on most Infiniti Fx35 applications is mounted near the EVAP canister, often accessible from underneath the rear of the vehicle or inside the wheel well without lifting the fuel tank. Disconnect the electrical connector and any attached vapor hoses, remove the mounting fastener or bracket clip, and install the new solenoid in reverse order. After installation, clear any stored EVAP codes and complete a full drive cycle to confirm the system passes its self-test.

Frequently asked questions

How much does it cost to replace vapor canister vent solenoids on a Infiniti Fx35?
The part itself starts at $56.95 on AutoBuffy. DIY installation typically adds no labor cost and takes under an hour for most Infiniti Fx35 owners. A shop will usually charge one to two hours of labor on top of the part price, making this one of the more affordable EVAP repairs you can face.
Can I drive my Infiniti Fx35 with a bad vapor canister vent solenoid?
Yes, in most cases your Infiniti Fx35 will remain drivable, but you should not ignore the fault. A stuck-closed solenoid can pressurize the fuel tank and make refueling difficult, while a stuck-open solenoid allows raw fuel vapors to vent to atmosphere. Either condition will cause your Infiniti Fx35 to fail an emissions inspection.
Will replacing the vapor canister vent solenoid clear the check engine light on my Infiniti Fx35?
Yes — once the faulty solenoid is replaced and the repair is confirmed, you can clear the stored EVAP code with an OBD-II scanner. The Infiniti Fx35's EVAP monitor will then run its self-test drive cycle, and the check engine light will stay off if no other faults are present. Allow one to two complete drive cycles for the monitor to complete.
How do I test a vapor canister vent solenoid on a Infiniti Fx35 before replacing it?
Disconnect the solenoid's electrical connector and use a multimeter to measure resistance across the two terminals — a reading that falls well outside the manufacturer's specified range indicates a failed coil. You can also apply direct 12-volt power to the solenoid and listen for an audible click, confirming the valve is opening and closing mechanically.
Is the vapor canister vent solenoid the same as the EVAP purge valve on my Infiniti Fx35?
No — they are two separate solenoids with opposite roles. The purge valve sits between the canister and the intake manifold and opens to pull stored vapors into the engine. The vent solenoid sits on the fresh-air side of the canister and controls outside airflow. Both are part of the same EVAP system and can set similar fault codes when they fail.
How long does a vapor canister vent solenoid last on a Infiniti Fx35?
Most vent solenoids last many years under normal driving conditions, but exposure to road debris, moisture, and heat cycles under the vehicle can shorten their lifespan. Vehicles operated in regions that use ethanol-blended fuel or experience wide temperature swings may see earlier failures due to seal degradation inside the solenoid valve body.
