Q: What does code P02C5 mean?

Cylinder 11 - Injector Leaking. P02C5 indicates that the powertrain control module (PCM) has detected a leaking condition in the fuel injector for cylinder 11, based on abnormal fuel trim or misfire patterns that suggest excess fuel is entering that cylinder. The code is typically set when the PCM's diagnostic strategy identifies a rich condition or injector performance outside the expected range for that specific cylinder.
