Vehicle Emission Control Information Decal

Vehicle Emission Control Information Decal (Typical):

Each vehicle is equipped with a decal containing emission control data that applies specifically to that vehicle and engine. The specifications provided 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 where an individual hose color will not agree with the schematic.
