Q: What does code P268A mean?

Fuel Injector Calibration Not Learned/Programmed. P268A indicates that the engine control module (ECM) has not successfully learned or stored the calibration values for one or more fuel injectors, which are critical for precise fuel delivery. The ECM detects this when the injector calibration data—typically a multi-digit code unique to each injector—is missing, corrupted, or has not been programmed into the module after service or replacement.
