ENGINE CALIBRATION LABEL

Fig. 1 Engine code information label:

An Emission Calibration Label is attached to the left-hand side door or door post pillar. It identifies the engine year, calibration design, and design revision level. These numbers are used to identify service parts and engine specifications that make up the emission system designed for the vehicle.

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.
