P0461 on RAM by model: symptoms, diagnosis and fix
The in-tank fuel level sending unit (float arm and variable-resistor card, part of the fuel pump module) wears out and gives false readings — commonly reading full then dropping to empty, sticking, or bouncing. On OBD-II trucks it sets P0463/P0462. It is one of the most-searched Ram gauge complaints and is separate from the instrument-cluster fault.
Common Symptoms
- Gauge reads full then suddenly drops to empty
- Gauge stuck on empty or full
- Erratic/bouncing needle
- Low-fuel light behaves incorrectly
How to Fix
Confirm the sender resistance sweep before replacing the cluster. Repair requires dropping the tank (or removing the bed) and replacing the fuel level sending unit — often done as a complete fuel pump/sender module for reliability. Avoid the cheapest unbranded senders, which frequently read wrong out of the box; use a quality module (Delphi/Spectra/Mopar). Parts $60-$250, with labor $150-$500.

Frequently asked questions
What does P0461 mean on a RAM?
P0461 stands for "Fuel Level Sensor 'A' Circuit Range/Performance." 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. On RAM it is documented across 1 model: 1500.
What are the most common causes of P0461?
The most common causes of P0461 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0461 on a RAM?
Published repair estimates on RAM range from $150 to $500 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.
