Dorman Vapor Canister Vent Solenoid for Select Nissan & Infiniti Models — Direct Replacement, Plug-and-Play

The Dorman 911-504 vapor canister vent solenoid is a direct-replacement EVAP vent valve engineered to restore proper evaporative emissions control on compatible Nissan and Infiniti models.

Modern engines rely on the evaporative emissions (EVAP) system to capture fuel vapors and route them for controlled combustion; when the vent solenoid fails the vehicle may trigger a check engine light or fail an emissions test. Dorman designed this vent solenoid as a plug-and-play replacement, built from durable materials and validated with endurance testing so it fits and functions like the original equipment part.

How will this vent solenoid affect my vehicle's emissions and diagnostics?

A faulty vent solenoid can let vapors escape or prevent proper purging of the canister, which often results in diagnostic trouble codes and the check engine lamp. Replacing the valve with the Dorman 911-504 helps reestablish correct venting and purge control so your onboard diagnostics can return to normal operation.

• Restores correct EVAP venting behavior for emissions control
• Helps eliminate common EVAP-related trouble codes
• Supports consistent purge cycles to reduce evaporative vapor loss

Is the Dorman 911-504 easy to install and will it fit my car?

Yes — this component is intended as a direct replacement with the same mounting and electrical connector layout as the original, enabling a simple plug-and-play swap. To ensure compatibility, use the vehicle lookup in the garage tool and review any fitment notes flagged by the information icon before ordering.

• Direct replacement design mirrors original equipment
• Standard electrical connector for quick reconnection
• Verify fit by entering year, make, and model in the compatibility tool

What materials and testing back the Dorman vent solenoid's reliability?

Dorman manufactures the 911-504 from premium components chosen for durability under thermal and chemical exposure common in the EVAP environment. The part undergoes simulation and endurance testing to confirm long-term performance and fit before it reaches the aftermarket.

• Premium construction resists wear and fuel vapor exposure
• Simulation and endurance tests validate function over time
• Produced by a supplier with over a century of automotive parts experience

When should I replace the vent solenoid and what symptoms indicate failure?

Replace the vent solenoid if you observe a persistent check engine light with EVAP-related codes, fuel smell near the vehicle, failed emissions test, or reduced engine idle stability linked to EVAP faults. Early replacement can prevent further EVAP system damage and resolve drivability or inspection issues.

• Persistent EVAP diagnostic trouble codes (DTCs)
• Fuel odor around the vehicle or cap area
• Failed emissions inspection tied to evaporative system

Who is this for: The Dorman 911-504 vapor canister vent solenoid is for vehicle owners, independent mechanics, and fleet technicians maintaining compatible Nissan and Infiniti models who need a reliable, OE-style replacement part. It suits anyone seeking a straightforward, tested solution to EVAP venting problems — verify fitment for your exact model year before purchase to ensure a seamless swap.
