What does code P0A5A mean?

Q: What does code P0A5A mean?

Generator Current Sensor Circuit Range/Performance. P0A5A indicates that the generator current sensor circuit is reporting a value outside its expected range or is not performing as designed. The powertrain control module (PCM) monitors the sensor's signal and sets this code when the voltage or current reading is implausible for the operating conditions, often due to a wiring fault, sensor degradation, or charging system issue.
