What does code P24BA mean?

Q: What does code P24BA mean?

EVAP System Leak Detection Pump Pressure Sensor Circuit Low. P24BA means the engine computer has detected a low-voltage signal from the pressure sensor built into the evaporative emission (EVAP) system's leak detection pump. The sensor's output is below the expected range, so the computer cannot trust the pressure reading used to test the fuel system for leaks.
