Q: What does code P02DF mean?

Cylinder 10 Fuel Injector A Offset Learning At Max Limit. P02DF means the engine computer has learned that cylinder 10's fuel injector needs the maximum allowed correction to deliver the right amount of fuel, and it can no longer compensate any further. The powertrain control module (PCM) monitors injector flow via crankshaft speed fluctuations and fuel trim, and it sets this code when the learned offset for that injector hits its calibration limit.
