Q: What does code P2D97 mean?

Starter/Generator Phase Z Current Sensor Circuit Low. P2D97 indicates that the powertrain control module has detected a low-voltage condition on the signal circuit of the phase Z current sensor, which monitors current flow in one phase of the starter/generator unit on hybrid and electric vehicles. The sensor's output is below the expected range for the given operating conditions, so the module cannot reliably measure phase current and sets this code.
