Dorman - OE Solutions Vapor Canister P/N:911-442
Dorman 911-631 vapor canister for the 2003-2004 Toyota Corolla 4-cylinder 1.8L and other vehicles stores fuel vapor in a charcoal filter element for the evaporative emissions system. The Dorman evap canister is sold to restore the vehicle's emissions controls when the original has failed.
A worn canister can show up as a fuel smell, an evaporative emissions check engine light or a failed emissions test. A cracked housing or a loose or split vapor hose can trigger the same light, so look over the canister body and its hoses for damage with the engine off before replacing anything. The car takes a single canister, and this listing is one.
The same canister for the 2003-2004 Toyota Corolla 4-cylinder 1.8L also fits the 2003-2004 Toyota Matrix 4-cylinder 1.8L and the 2003-2004 Pontiac Vibe 4-cylinder 1.8L.
