Vehicle Emission Control Information
Typical VECI Decal (Federal Models):
Typical VECI Decal (California Models):
Each vehicle has a decal containing emission control information that applies specifically to the vehicle and engine. The specifications on the decal are critical to servicing emissions systems.
In addition to the tune-up specifications and procedures, the emission decal shows a color-coded schematic of the engine vacuum system. The color coding on the schematic represents the actual color coding on the vacuum hoses. However, there will be instances when a hose color does not match the color on the decal.
Typical location of the decal will be on the underside of the hood or the radiator support sight shield.
