Q: What does code P268C mean?

Cylinder 1 Injector Data Incompatible. P268C means the engine control module (ECM) has received injector characterization data from cylinder 1's injector that does not match the values it expects for that injector or that are internally inconsistent. The ECM compares the injector's stored calibration or coding against its own programmed data and flags the circuit as incompatible when the two do not agree.
