Emission Control Systems: Application and ID
VEHICLE EMISSION CONTROL INFORMATION (VECI)VECI Decal
VECI Decal:
Engine Family Group Work Sheet:
Evaporative Family Name Work Sheet:
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 Location
Typical location of the decal will be on the underside of the hood or the radiator support sight shield.
Engine/Evaporative Emission System Information
VECI Decal:
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 work sheet for decoding information.
Base Engine Calibration Information
Calibration Location On VC Label:
Base engine calibration information, also referred to as the powertrain calibration, is located in the lower right corner of the VC label. Engine calibration information is limited to a maximum of 5 characters per line (2 lines maximum). Calibration information more than 5 characters long will wrap to the second line of this field. Only the base calibration will appear on this label. The revision level is no longer printed on the label; however, it can be found in on-line automotive service information system (OASIS). For more information on VC label or engine calibration, refer to Vehicle/Application and ID, Identification Codes.
Decal Location
The VC label is on LH door or door post pillar.
