Q: What does code P25B2 mean?

Fuel Level Sensor A or B Stuck. P25B2 means the engine computer has determined that fuel level sensor A or B is stuck, typically because the signal from the sensor has not changed over a long period or has remained outside a plausible range despite fuel being added or consumed. The computer compares fuel level readings against other inputs such as fuel consumption and fuel tank pressure, and when the readings fail to move as expected, it flags the sensor as stuck.
