Q: What does code P2DCB mean?

Starter/Generator Phase X-Y-Z Current Sensor Correlation. This code indicates that the powertrain control module has detected an implausible relationship between the current sensors for the three phases of the starter/generator unit, which is the motor-generator assembly used in many hybrid and electric vehicles. The computer compares the current reported by each phase sensor and flags a correlation error when the readings do not align within the expected tolerance during operation.
