Ford F150 Pickup. Instruction - part 1649

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 
"2" to denote a 2-valve engine versus using "4" to denote a 4-valve engine, provides an easily identifiable 
difference.  

Position 5 = Fleet Code
