P25B0Fuel Level Sensor A Stuck

P25B0 indicates that the powertrain control module (PCM) has detected a condition where the fuel level sensor A signal is stuck within a narrow range and is not changing as fuel is consumed or added. The PCM monitors the sensor voltage over time and flags the code when the reading fails to move despite expected changes in fuel volume.
