Position 4 = Unique Calibration

1. The Emissions/CAFE/CO2 Compliance Department is responsible for assigning these calibration codes. Unique calibration identifications are assigned to cover similar vehicles to differentiate between tires, drive configurations, final drive ratios and other calibration-significant factors. These 2 characters are selected by an analyst to provide identifiable information unique to each calibration. For example; using the number 2 to denote a 2-valve engine versus using the number 4 to denote a 4-valve engine, provides an easily identifiable difference.
