What does P0461 mean in plain words?

The fuel level signal never changes the way real fuel consumption should — often a stuck float or worn sender track. Watch the gauge across a full tank of driving; a needle frozen at one reading while miles accumulate is this code's signature.

Can I drive with a broken fuel gauge?

Mechanically yes — track miles with the trip odometer and refill early. The hidden costs: EVAP monitors may not run (inspection readiness) and running genuinely low overheats the in-tank pump that the fuel normally cools.

Why does my gauge work but the code persists?

The computer watches the signal's plausibility over time, not just the needle. A dead spot the needle skips past quickly still logs. Live data shows what the gauge hides.

P0461 — Fuel Level Sensor Range/Performance

Low

Quick answer

P0461 means the fuel level signal never changes the way real fuel consumption should — often a stuck float or worn sender track. First move: watch the gauge across a full tank of driving; a needle frozen at one reading while miles accumulate is this code's signature.

What it means

P0461 reports that the fuel level signal never changes the way real fuel consumption should — often a stuck float or worn sender track.

The fuel level sender is a float on an arm sweeping a resistive track inside the tank, usually built into the fuel pump module. It affects nothing about how the engine runs — but it does affect the EVAP system's leak tests (which need a known fuel level) and, more practically, whether you can trust your gauge.

The steps below run cheapest-first — because in this family, the cheap causes really are the common ones.

P0461 symptoms: what you'll notice

The needle stays frozen at one reading while you burn through miles of fuel.
Check engine light with no change at all in how the car drives.
Distance-to-empty stops counting down, or shows the same number for days.
You only learn the real fuel level at the pump — the tank takes far more (or less) than the gauge promised.

How to fix it: diagnosis, step by step

Cheapest and most likely checks first.

1 Characterize the gauge

Stuck full, stuck empty, frozen mid-tank, or jumpy over bumps — each points differently (open circuit, short, dead spot on the track, loose float arm).
2 Test at the tank connector

Most senders are a simple variable resistance: measure at the tank-module connector and compare against the spec range from empty to full. Wiring to the gauge gets tested the same way.
3 Plan the repair realistically

The sender usually comes as part of the fuel pump module. If the pump is original and high-mileage, replacing the whole module while the tank is down is the once-not-twice decision.
