Wells 4B1490 EVAP Vapor Canister Charcoal Canister Emission Control

The Wells 4B1490 Vapor Canister is a direct-fit replacement charcoal canister designed for the vehicle's Evaporative Emission Control System (EVAP). The vapor canister stores and contains harmful fuel vapors from the fuel system that would otherwise be released into the atmosphere, helping the vehicle meet emissions standards and protect air quality.

Key Features:

• Engineered and tested to match OE parts in fit, form, and function
• Compatible with both domestic and imported vehicles
• Activated charcoal construction absorbs and holds fuel vapors until the engine can burn them
• Direct replacement for a failed or saturated EVAP canister
• Helps resolve EVAP-related diagnostic trouble codes (P0440, P0441, P0442, and related)
• Helps eliminate fuel odor caused by vapor leaks

The vapor canister — also commonly called a charcoal canister or EVAP canister — is typically located near the fuel tank. When the canister fails, symptoms can include a illuminated check engine light, fuel odor, failed emissions testing, or EVAP-related fault codes. The Wells 4B1490 restores proper EVAP system function and supports OBD-II monitor readiness.
