Emission Calibration Label
The emission calibration number label is located on the LH door jamb. It identifies the engine calibration number, the engine code number, and revision level.
These numbers are used to determine if parts are unique to specific engines.
Always refer to these labels when replacement parts are required or when checking engine calibrations. Engine parts often differ within a family. Verification of identification codes will ensure that the proper parts are obtained. The codes contain all pertinent information relating to dates, optional equipment, and revisions. The Ford Master Parts Catalog contains a complete listing of the codes and their application.
