Q: What does code P0A58 mean?

Drive Motor B Current Sensor Circuit High. P0A58 indicates that the hybrid or electric vehicle control module has detected an abnormally high voltage signal from the current sensor circuit monitoring drive motor B, which is the second traction motor in a multi-motor hybrid system. The computer expects the sensor's output to stay within a calibrated range that corresponds to the actual current flowing through the motor, and a high signal means the reported current exceeds what the system can safely command or verify.
