Each fuel injector has a six-digit alphanumeric correction code. The correction code is printed on the intake side of the fuel injector (1) and is used to
identify injector calibration. When replacing any fuel injectors, this code must be entered into the vehicles Engine Control Module (ECM) using a
diagnostic scan tool. In addition, if a new ECM is installed, use a diagnostic scan tool to program all six of the injector codes from the original fuel
injectors into the new ECM.
