Typical Vehicle Emission Control Information (VECI) Decal

Engine emission control systems vary depending on vehicle model, vehicle type, engine and vehicle weight. Always refer to the underhood VECI decal for emission control systems information.

Vacuum hoses on the engine use a color stripe to aid in hose routing checks. The stripe will usually be the same color as on the VECI decal, but the correct vacuum hose routing must be verified by using the correct component connections shown on the VECI decal.
