What does code P02A5 mean?

Q: What does code P02A5 mean?

Cylinder 3 - Injector Leaking. P02A5 indicates that the powertrain control module has detected a leaking condition in the fuel injector for cylinder 3, typically by monitoring fuel trim or pressure behavior that deviates from expected values. The computer interprets this as excess fuel entering the cylinder when the injector should be closed, which can upset the air-fuel ratio and trigger the warning light.
