What does code P2DCC mean?

Q: What does code P2DCC mean?

Starter/Generator Position Sensor Correlation. P2DCC indicates that the engine control module (ECM) has detected a disagreement between the position signals from the starter/generator unit, which is the combined motor-generator used on many hybrid and mild-hybrid vehicles. The ECM compares the resolver or encoder outputs that report the rotor angle and speed, and it sets this code when the correlation between those signals falls outside the expected range.
