Manage the fresh-air side of your truck's EVAP system with the Standard Ignition Vapor Canister Vent Solenoid CP3584. It controls the flow of fresh air into the charcoal vapor canister and drops in as a direct-fit replacement for the 2015-2016 Chevrolet Silverado 1500 and 2015-2016 GMC Sierra 1500 — see the Buyer's Guide tab to confirm your engine.
Engineered specifically for GM vehicles, and designed and manufactured in North America. If a failed vent solenoid is the cause of an EVAP fault code or a fuel-system leak-test failure, this replaces it — diagnose the cause before replacing. Signs it may need replacing include a stored EVAP/leak-detection trouble code or a solenoid that no longer seals or opens.
