DTC P25B0-00: Fuel Level Sensor 'A' Stuck: General Description
WARNING: This page is about a different car, the 2021 Kia Soul. However, it is still accessible from the selected car via links, so may be relevant.
The Fuel Level Sender (FLS) measures the fuel level in fuel tank and its information is used to supply the ECM with information regarding the monitoring condition of the Evaporative Emission (EVAP) canister purge system for leak detection. If the FLS is monitored for high or low stuck or difference between voltage of FLS and voltage deviation of FLS is exceeds limited value while driving, this is interpreted by the ECM as a fault.
