Dorman 911-525 Vapor Canister Vent Solenoid Evaporative Emissions Replacement

The Dorman 911-525 is a direct-replacement vapor canister vent solenoid designed to restore proper operation of your vehicle's evaporative emissions (EVAP) system. A faulty vent solenoid is a common trigger for a check engine light, and this OE-style replacement allows for a straightforward, plug-and-play repair without dealer pricing.

The EVAP vent solenoid controls the flow of fresh air into the charcoal canister, allowing the system to purge stored fuel vapors into the intake manifold. When the solenoid fails — whether it sticks open, sticks closed, or develops an electrical fault — the ECM detects the leak and sets a diagnostic trouble code (DTC), most commonly P0446 or related EVAP codes.

Key Features:

• Direct OE Replacement — engineered to fit and function like the original factory part with no modification required
• Premium Materials — constructed from quality materials for extended service life in underhood conditions
• Plug-and-Play Installation — uses the factory wiring connector and mounting location for straightforward installation
• Simulation and Endurance Tested — validated through rigorous testing to ensure proper fit and reliable performance
• Clears Check Engine Light — restores EVAP system integrity to extinguish EVAP-related diagnostic trouble codes

Dorman Products has been engineering aftermarket automotive replacement parts for over 100 years, offering OE-quality solutions at a competitive price point. The 911-525 is also commonly referenced as an evaporative emissions canister vent valve or EVAP vent control valve.
