Q: What does code P2DC1 mean?

Starter/Generator Phase X Current Sensor Circuit. P2DC1 indicates that the powertrain control module has detected an abnormal current reading from the phase X current sensor circuit of the starter/generator unit, which is part of a mild-hybrid or integrated starter-generator system. The computer compares the sensor signal against expected values and sets this code when the current is out of range, intermittent, or implausible for the operating conditions.
