What does code P2541 mean?

Q: What does code P2541 mean?

Low Pressure Fuel System Sensor Circuit Low. P2541 means the engine computer has detected an abnormally low voltage signal from the low-pressure fuel system sensor, which typically monitors fuel pressure or temperature on the supply side before the high-pressure pump. The computer expects a voltage within a calibrated range, and a reading below the minimum threshold for a set time triggers this code.
