Dorman Vapor Canister Vent Solenoid EVAP Vent Valve — 911-504 Direct-Fit Replacement, Plug-and-Play

The Dorman 911-504 Vapor Canister Vent Solenoid is a direct-fit replacement EVAP vent valve designed to restore proper evaporative emissions control and stop check-engine light triggers.

If your vehicle is showing an EVAP-related trouble code or the check-engine warning points to the vent circuit, the vent solenoid is a common service item. Dorman engineered this vent solenoid to match original equipment form and function while using durable materials to withstand under-hood environments. It installs using the existing connector and mounting points for a straightforward swap without vehicle-specific reprogramming.

How will this vent solenoid affect my vehicle’s EVAP system?

The vent solenoid controls airflow into the charcoal canister so the fuel system can breathe during purge cycles. A failed solenoid can cause improper purge, store pressure errors in the EVAP system, and trigger diagnostic trouble codes. Replacing the faulty valve helps re-establish the designed venting pattern and reduces false fault detection.

• Restores commanded vent/open and closed positions under ECU control
• Prevents vacuum or pressure buildup in the fuel tank evaporative circuit
• Reduces the chance of recurring EVAP diagnostic trouble codes

Is the Dorman 911-504 an easy install for DIY mechanics?

Yes — this part is built as a plug-and-play replacement to use the vehicle's existing wiring and mounting points. Basic hand tools and light mechanical knowledge are typically all that’s needed for removal and installation. Always verify fit with the vehicle lookup tool before purchase to confirm any model-specific notes.

• Uses original connector and bolt pattern for straightforward swap
• No calibration or ECU reprogramming required in most applications
• Installation time generally under one hour on accessible vehicles

What materials and testing back this replacement part?

Dorman manufactures the 911-504 using materials selected for corrosion resistance and thermal stability so the valve endures under-hood conditions. The part undergoes simulation and endurance testing that mirrors operational stresses to ensure consistent performance. The result is a reliable replacement expected to meet or exceed the service life of the original component.

• Constructed from premium plastics and corrosion-resistant metal components
• Performance verified by simulated operational and endurance tests
• Produced by a supplier with decades of automotive replacement experience

How do I confirm this vent solenoid fits my vehicle?

Before ordering, enter your vehicle information into the seller’s garage tool and check the Confirmed Fit indicator at the top of the product page. If a blue "i" appears, hover or click for fitment notes that explain any exceptions or additional verification steps. Proper fit verification avoids returns and ensures correct function after installation.

• Use the online vehicle lookup to match year, make, model, and engine
• Review any fitment notes tied to the blue “i” icon for specific exceptions
• Contact support with VIN details if you need extra confirmation
