Dorman Vapor Canister Vent Solenoid EVAP Valve — 911-504 Direct-Replace, OE Fit & Durable

The Dorman 911-504 vapor canister vent solenoid is a direct-replacement EVAP system valve engineered to restore proper venting and help resolve related diagnostic trouble codes.

When the evaporative emissions (EVAP) system signals a fault, a failed vent solenoid is a common culprit. Dorman's 911-504 is built as a plug-and-play replacement designed to match original equipment function while resisting wear from heat, fuel vapors, and vibration. Choosing a quality replacement part reduces the risk of recurring faults and avoids the extra cost and time of repeated diagnostics.

How does the Dorman 911-504 help with engine light or EVAP codes?

If the vehicle computer detects abnormal flow or sealing in the EVAP system, it will set a diagnostic trouble code and may illuminate the check engine light. Replacing a faulty vent solenoid like the Dorman 911-504 can restore correct venting and sealing behavior, helping clear the condition once the system is cycled and codes are reset.

• Direct replacement designed to match OE fit and function for straightforward swap-in installation.
• Quality materials resist vapors and heat to maintain reliable operation under service conditions.
• Tested for fit and endurance to reduce rework from early failure.

What should I expect during installation and fit verification?

Installation is intended to be plug-and-play: disconnect the battery per vehicle procedure, unplug the old solenoid, remove hardware if applicable, and install the Dorman unit in the same orientation. Before buying, use the retailer’s vehicle lookup and Confirmed Fit information to verify compatibility; hover over any informational icon to view vehicle-specific notes.

• Simple electrical connector match to original harness for quick replacement.
• Same mounting footprint for reuse of OE brackets or fasteners.
• Follow vehicle-specific instructions and safety steps when servicing fuel/EVAP components.
