What does code P1432 mean?

Q: What does code P1432 mean?

Fuel Level Sensor 2 Circuit Low Voltage. P1432 on a GM vehicle means the powertrain control module (PCM) has detected a low voltage signal on the fuel level sensor 2 circuit, which is the secondary fuel level sender used on vehicles with dual tanks or a transfer pump system. The PCM monitors the signal voltage from the sensor and sets this code when the voltage stays below the expected threshold for a calibrated amount of time, indicating a short to ground, an open circuit, or a failed sensor.
