Q: What does code P02B5 mean?

Cylinder 7 - Injector Leaking. P02B5 indicates that the engine control module has detected a leaking condition in the fuel injector for cylinder 7, typically by monitoring fuel trim or pressure behavior that suggests excess fuel is entering that cylinder when it should not. The computer sets this code when the injector's electrical or flow characteristics fall outside the expected range for a sealed, non-leaking injector.
