Q: What does code P01DF mean?

Cylinder 11 Injection Timing Performance - Over Retarded. P01DF indicates that the powertrain control module (PCM) has detected the fuel injection timing for cylinder 11 is more retarded than the manufacturer's calibrated limit during engine operation. The PCM monitors the injection event via crankshaft and camshaft position signals and sets this code when the commanded timing cannot be achieved or when the actual timing deviates excessively toward retard.
