This code contains information about the nozzles and the difference between them and the ideal one.

As a result of the repair, the characteristics of the injector change significantly, so it is necessary to immediately assign the injector new codes C2i or C3i that correspond to its new characteristics. Code generation is a complex process that requires special test equipment and software.

Next, this code is registered in the EBC (Electronic Control Unit) of the engine, so that the "brain" of the car makes corrections in the operation of the injector regardless of revolutions and loads, in order to optimize the operation of the injectors in different operating modes.
