VEHICLE EMISSION CONTROL INFORMATION (VECI)

VECI Decal
Each vehicle has a VECI decal containing emission control information that applies specifically to the vehicle and engine. The specifications on the decal are critical to repairing emissions systems.

VECI Decal:

Engine Family Group Work Sheet:

Evaporative Family Name Work Sheet:

VECI Decal Location
The typical location of the decal is on the underside of the hood or the radiator support sight shield.

Engine/Evaporative Emission System Information
Manufacturers must use a standardized system for identifying their individual engine families. The engine family group and the evaporative family name consists of 12 characters each.

Both the engine family group and the evaporative family name are listed in the box on the emission decal as indicated in the area marked as engine evaporative family information. The first line contains the engine size and the 12-character engine family group. The second line contains the 12-character evaporative family name information. Both the engine family group and the evaporative family name are specific to the vehicle. Please refer to the Engine Family Group and the Evaporative Family Name worksheet for decoding information.
