Q: What does code P2DC3 mean?

Starter/Generator Phase Y Current Sensor Circuit. P2DC3 indicates that the engine control module has detected an abnormal signal from the phase Y current sensor circuit of the starter/generator unit, which is the motor-generator assembly used on many hybrid and mild-hybrid vehicles. The computer compares the sensor's reported current against expected values for the commanded operating state and sets this code when the signal falls outside the valid range or is implausible.
