P0462 on Nissan
Fuel Level Sensor 'A' Circuit Low Input
P0462 on Nissan vehicles indicates fuel level sensor 'a' circuit low input. Au7o has documented this code across 2 Nissan models — most commonly on Armada, Juke. 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. Typical repair costs on Nissan range from $250 to $900, depending on the specific model and root cause.
Common Causes of P0462
- •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)
P0462 on Nissan by Model
Nissan Armada(1 issue)
- Fuel Level Sender Card Failure Causing Gauge to Stick Above Empty2005-2009
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.
Nissan Juke(1 issue)
- Fuel Level Sender Failure - Gauge Sticks or Reads High and Car Runs Out of Fuel With No Warning2011-2017
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.

What does P0462 mean on 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 specifically, this code is documented across 2 models.
What causes P0462 on Nissan vehicles?▼
Common causes on Nissan: 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.
