What does code P2D93 mean?

Q: What does code P2D93 mean?

Starter/Generator Phase Y Current Sensor Circuit High. P2D93 indicates that the vehicle's control module has detected an abnormally high voltage on the signal circuit of the phase Y current sensor, which monitors current flow through one phase of the starter/generator unit. This high signal voltage is outside the expected range and can be caused by a short to voltage, a faulty sensor, or a wiring issue, potentially affecting the proper operation of the starter/generator system.
