What does code P2DBE mean?

Q: What does code P2DBE mean?

Battery Charger B Coupler Lock Position Sensor Circuit Low. P2DBE indicates that the powertrain control module has detected a low-voltage condition on the signal circuit of the battery charger B coupler lock position sensor, which monitors whether the charging coupler is fully latched. The sensor's output is below the expected range, so the module cannot reliably confirm the coupler's locked state and sets this code to flag the circuit fault.
