P02DF Cylinder 10 Fuel Injector A Offset Learning At Max Limit
The per-cylinder injector offset on cylinder 10 has reached its maximum value — the injector is delivering significantly less fuel than the calibrated reference, and the controller cannot trim it any further.
Is it safe to drive with P02DF?
Usually safe for short trips, but don’t ignore it: the underlying fault can get more expensive over time.
