P0463 on Nissan
Fuel Level Sensor Circuit High Input
P0463 on Nissan vehicles indicates fuel level sensor circuit high input. Au7o has documented this code across 1 Nissan model — most commonly on Rogue. 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 Nissan range from $250 to $600, 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 Nissan by Model
Nissan Rogue(1 issue)
- Inaccurate fuel gauge / faulty fuel level sender2014-2016
A frequently reported issue (nearly 200 reports) is an inaccurate fuel gauge driven by a failing fuel level sending unit inside the tank. Owners see the gauge read full when the tank is half empty, read near-empty with a full tank, the low-fuel warning trigger prematurely, or the gauge start at zero on key-on. The float/sender resistance drifts out of spec, sometimes setting code P0463 (fuel level sensor circuit high input). Nissan has issued recalls for the same part on the Altima/Frontier but not (for most years) on the Rogue.

What does P0463 mean on Nissan?▼
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 Nissan specifically, this code is documented across 1 model.
What causes P0463 on Nissan vehicles?▼
Common causes on Nissan: 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.
