Code P0464 2015 Chevrolet Silverado Description
The primary fuel level sensor and the secondary fuel level sensor change resistance based on fuel level. The Fuel Pump Driver Control Module monitors the signal circuits of the primary fuel level sensor and the secondary fuel level sensor and sends the signal information to the Engine Control Module (ECM) for all further handling. The ECM uses this value in order to determine the fuel level. When the fuel tank is full, the resistances of both fuel level sensors are low, and the ECM senses a low signal voltage on both the signal circuits of the primary fuel level sensor and the secondary fuel level sensor. When the fuel tank is empty, the resistances of the fuel level sensors are high, and the ECM senses a high signal voltage. The ECM uses the signal circuits of the primary fuel level sensor and the secondary fuel level sensor in order to calculate the percentage of remaining fuel in the tank. The ECM sends the fuel level percentage via the serial data circuit to the instrument cluster in order to control the fuel gauge.

The ECM uses the signal circuits of the primary fuel level sensor and the secondary fuel level sensor in order to calculate the percentage of remaining fuel in the tank. The ECM sends the fuel level percentage via the serial data circuit to the instrument cluster in order to control the fuel gauge.
The Diagnostic Trouble Code (DTC) will be set if the ECM detects the fuel level change is greater than 10% for a duration lasting less than 30 seconds.
What are the Possible Causes of the DTC P0464 2015 Chevrolet Silverado?
- Faulty Fuel Level Sensor
- Fuel Level Sensor harness is open or shorted
- Fuel Level Sensor circuit poor electrical connection
- Faulty Instrument Cluster
- Faulty Engine Control Module (ECM)
