Dorman - OE Solutions Vapor Canister Vent Solenoid P/N:911-522
Replace a faulty vent valve in your evaporative emissions system with the Dorman vapor canister vent solenoid, part number 911-021 from Dorman OE Solutions. It is an evaporative emissions canister vent valve repair kit and does not include the filter assembly. It fits many vehicles, among them the 2004-2005 Chevrolet Silverado 1500, 2004-2005 GMC Sierra 1500 and 2004 Chevrolet Silverado 2500. See the "Vehicles it fits" section for the full list and engine details.
The vent solenoid controls the fresh-air side of the vapor canister. It opens to let air in as fuel vapor is purged, and it closes so the system can be sealed for leak checks. A malfunctioning vent solenoid can turn on the check engine light. If a failed vent solenoid is the cause, this unit replaces it and is designed to support proper operation of the vehicle's evaporative emissions system.

What does a Dorman canister vent valve solenoid do?
It controls the vent side of the EVAP vapor canister. It opens to let fresh air in during purge and closes so the system can be sealed for leak testing.
Does this kit include the filter assembly?
No. Dorman lists 911-021 as an evaporative emissions canister vent valve repair kit without the filter assembly.
What are signs the vent solenoid may need replacing?
A malfunctioning vent solenoid can turn on the check engine light. A stuck vent may also set EVAP codes or make refueling difficult. Diagnose the cause first, because other EVAP parts can cause the same signs.
Is the installation difficult?
Dorman designed it as a direct replacement with plug-and-play installation. Consult your vehicle's service information for the solenoid's location and the removal procedure.
Will it fit my 2004-2005 Chevrolet Silverado 1500?
Yes, it is listed for the 2004-2005 Chevrolet Silverado 1500 and the 2004-2005 GMC Sierra 1500. Check the "Vehicles it fits" section to confirm your exact vehicle and engine.
