ENGINE EMISSION CALIBRATION LABEL

Engine Emission Calibration Number Label:

An Emission Calibration Label is attached to the LH side door or LH door post pillar. It identifies the engine calibration number, engine code number, and revision level. These numbers are used to determine if parts are unique to specific engines with a CID family.


EXAMPLE OF CALIBRATION CODE 0-25F-R00

The first number represents the model year in which the Calibration was first introduced. 0 = 1990

The second group represents the design level assigned to the engine (25F).

The third group represents the revision level of the calibration (R00). These numbers advance as revisions occur.
