What does code P2D94 mean?

Q: What does code P2D94 mean?

Starter/Generator Phase Z Current Sensor Circuit High. P2D94 indicates that the powertrain control module has detected an abnormally high voltage signal from the phase Z current sensor circuit of the starter/generator unit. This sensor monitors current flow in one phase of the integrated motor-generator, and a high reading typically points to a wiring fault, a failed sensor, or an internal issue within the starter/generator assembly.
