P0462 on Nissan by model: symptoms, diagnosis and fix
The in-tank fuel level sending unit uses a resistive card that the float arm wipes across. On TA60 Armadas (shared with the Titan and QX56) the card wears/corrodes and the float can also hang up, so the gauge reads roughly 1/4 tank when the tank is actually empty, or sticks on Full and never moves. Owners run out of fuel with the needle still showing reserve. Nissan issued recall 10V074000 covering 2005-2009 Titan/Armada/QX56 for an inaccurate fuel gauge reading, replacing the sender with an improved sender card, but many VINs were left out of the recall population and the same failure keeps appearing on non-covered trucks.
Common Symptoms
- Fuel gauge never reads below 1/4 tank
- Ran out of fuel with gauge showing fuel remaining
- Fuel gauge stuck on Full
- Erratic or jumpy fuel needle
- Distance-to-empty readout wildly wrong
- Low fuel warning light never illuminates
How to Fix
Replace the fuel level sender unit inside the tank with the updated sender card (dealer performs free of charge on VINs covered by recall 10V074000). Out of recall, the tank must be dropped and the sender/pump module assembly replaced; a fresh fuel filter sock and a check of the tank for debris is worthwhile at the same time. Reflashing or replacing the combination meter does not fix it - the fault is in the tank.

The Juke's saddle-shaped fuel tank uses two level senders: a primary unit on the pump module and a secondary sender on the opposite side that also drives the transfer jet pump. When the secondary sender's resistance card wears through, the gauge stops tracking properly - typical owner reports are a needle that will not move after a fill-up, a distance-to-empty that never changes, or a gauge frozen between half and three-quarters that never reaches empty. The dangerous part is that the low-fuel warning never illuminates, so the engine stalls unexpectedly in traffic with the gauge still showing fuel. Failure of one sender commonly upsets the reading from the other, which is why partial-range faults are the norm rather than a dead gauge.
Common Symptoms
- Fuel gauge does not move after refueling
- Gauge stuck between 1/2 and 3/4 and never reads empty
- Distance-to-empty readout frozen or wildly wrong
- Low fuel warning light never comes on
- Engine stalls from fuel starvation with fuel showing on the gauge
- Gauge needle jumps erratically
How to Fix
Have the sender resistance swept with a scan tool live-data reading while the level changes, and check the fuel-gauge circuit and instrument cluster before condemning parts. The repair is replacement of the failed sender - the primary unit comes with the in-tank pump module under the rear seat access panel, while the secondary sender usually requires lowering the tank. Have the fuel pump module gasket replaced at the same time. Until it is fixed, track fuel by trip-meter mileage, not by the gauge.

Frequently asked questions
What does P0462 mean on a Nissan?
P0462 stands for "Fuel Level Sensor 'A' Circuit Low Input." P0462 indicates the powertrain control module detected a fuel-level sensor signal voltage that is lower than the normal operating range — often interpreted as an empty or near-empty reading that may not reflect the actual fuel amount. The fuel level sender reports tank level via a variable resistance, and an abnormally low signal can stem from a short to ground or a failed sender. This usually shows up as a stuck-low or inaccurate fuel gauge rather than a driving problem. It is low-urgency but should be corrected so the gauge and EVAP monitors work properly. On Nissan it is documented across 2 models: Armada, Juke.
What are the most common causes of P0462?
The most common causes of P0462 are: Faulty fuel level sensor / sending unit, Short to ground in the signal wire, Corroded or damaged connector at the fuel pump module, Open or high-resistance ground circuit, Worn sender resistor card or float, Damaged wiring harness to the tank, Instrument cluster or PCM fault (less common). The specific cause varies by vehicle.
How much does it cost to fix P0462 on a Nissan?
Published repair estimates on Nissan range from $250 to $900 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
