Q: What does code P2DC5 mean?

Starter/Generator Phase Z Current Sensor Circuit. P2DC5 indicates that the powertrain control module has detected an abnormal electrical condition in the phase Z current sensor circuit of the starter/generator unit, which is the motor-generator assembly used on hybrid and mild-hybrid vehicles. The computer monitors the current sensor signal to verify that the phase winding current stays within an expected range during starter and generator operation, and it sets this code when the signal voltage or current reading falls outside that calibrated window.
