P0463 on Volvo
Fuel Level Sensor Circuit High Input
P0463 on Volvo vehicles indicates fuel level sensor circuit high input. Au7o has documented this code across 1 Volvo model — most commonly on V50. This code means the fuel level sensor is reporting a voltage that is higher than the computer expects, which usually translates to a reading suggesting the tank is fuller than possible (such as more than full). The fuel level sensor is the float-and-sender unit inside the fuel tank that tells the gauge and computer how much fuel remains. A high-input signal points to an electrical problem like a short to voltage or an open in the sensor circuit, rather than an actual fuel issue. Besides an inaccurate or pinned fuel gauge, it can disturb EVAP system monitoring that uses fuel level data. Typical repair costs on Volvo range from $300 to $800, depending on the specific model and root cause.
Common Causes of P0463
- •Faulty fuel level sensor/sending unit (float stuck or worn)
- •Open circuit in the fuel level sensor wiring
- •Short to voltage in the sensor circuit
- •Corroded or loose connector at the tank or sending unit
- •Damaged or stuck float arm inside the tank
- •Faulty instrument cluster or gauge driver
- •Faulty PCM/ECM (rare)
P0463 on Volvo by Model
Volvo V50(1 issue)
- In-Tank Fuel Pump Module Failure2005-2011
The Volvo V50 fuel pump module located inside the fuel tank can fail, causing starting issues and stalling. The fuel level sender can also fail separately, causing inaccurate fuel gauge readings.

What does P0463 mean on Volvo?▼
P0463 stands for "Fuel Level Sensor Circuit High Input." This code means the fuel level sensor is reporting a voltage that is higher than the computer expects, which usually translates to a reading suggesting the tank is fuller than possible (such as more than full). The fuel level sensor is the float-and-sender unit inside the fuel tank that tells the gauge and computer how much fuel remains. A high-input signal points to an electrical problem like a short to voltage or an open in the sensor circuit, rather than an actual fuel issue. Besides an inaccurate or pinned fuel gauge, it can disturb EVAP system monitoring that uses fuel level data. On Volvo specifically, this code is documented across 1 model.
What causes P0463 on Volvo vehicles?▼
Common causes on Volvo: Faulty fuel level sensor/sending unit (float stuck or worn), Open circuit in the fuel level sensor wiring, Short to voltage in the sensor circuit, Corroded or loose connector at the tank or sending unit, Damaged or stuck float arm inside the tank. Specific causes vary by model and year — see the per-model sections below.
