What does code P02D4 mean?

Q: What does code P02D4 mean?

Cylinder 5 Fuel Injector A Offset Learning At Min Limit. P02D4 means the engine computer has learned that the fuel injector for cylinder 5 needs the maximum allowed correction to its opening time, and it can no longer compensate any further. The computer stores this code when the injector's offset learning value sits at the minimum limit during its self-test, indicating the injector is flowing more fuel than expected or the electrical circuit is behaving outside the normal window.
