P0461 on Infiniti
Fuel Level Sensor 'A' Circuit Range/Performance
P0461 on Infiniti vehicles indicates fuel level sensor 'a' circuit range/performance. Au7o has documented this code across 2 Infiniti models — most commonly on FX35, M35. P0461 means the powertrain control module sees a fuel-level sensor signal that is implausible or doesn't change as expected — for instance, the reading stays fixed while fuel is consumed, or it moves erratically. The fuel level sensor (sending unit) in the tank reports how much fuel remains, and this data is also used by the EVAP system for certain leak monitors. Typically this only causes an inaccurate fuel gauge or skipped emissions tests rather than drivability problems. It is a low-urgency issue but worth fixing for an accurate gauge. Typical repair costs on Infiniti range from $300 to $900, depending on the specific model and root cause.
Common Causes of P0461
- •Faulty fuel level sensor / sending unit in the tank
- •Worn or dirty sending-unit resistor card or float
- •Wiring or connector problems to the sending unit
- •Corrosion at the fuel pump module connector
- •Stuck or damaged float arm
- •Poor ground for the sensor circuit
- •Instrument cluster or PCM fault (less common)
P0461 on Infiniti by Model
Infiniti FX35(1 issue)
- Fuel Gauge Sending Unit Failure2003-2012
A common Nissan/Infiniti issue on this era of FX35 is inaccurate fuel level readings caused by wear or contamination of the fuel level sending unit inside the tank. Owners report the gauge sticking, dropping suddenly, or showing empty with fuel still in the tank, sometimes accompanied by a check engine light.
Infiniti M35(1 issue)
- Fuel Gauge Sending Unit Failure2006-2010
Some M35 owners report inaccurate fuel level readings, including gauges that stick, read empty when fuel remains, or fluctuate unexpectedly. The issue is commonly related to wear or contamination in the fuel level sending unit inside the tank, which can affect trip planning and trigger low-fuel warnings incorrectly.

What does P0461 mean on Infiniti?▼
P0461 stands for "Fuel Level Sensor 'A' Circuit Range/Performance."
