P0461
Fuel Level Sensor Range/Performance
Severity
low
Lowest on our scale. Fix it when convenient.
Can you drive it
Only if running normally
A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety.
Indicative cost (USD)
$300–$800
Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
Fuel level readings out of plausible range.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

P0461 sets when the PCM sees fuel level sensor readings that change implausibly slowly, jump erratically, or fail to track fuel consumption inferred from injector pulse width over a drive cycle.
Cheapest-first ladder
- pull live data and watch the fuel level PID (volts or percent) while you add a known quantity of fuel.
- A healthy sender sweeps smoothly from roughly 0.2 to 4.5 volts (or 0 to 250 ohms on resistive senders) as the tank fills.
- Flat-lining at one value, stair-stepping, or dead spots in the middle of the sweep point to a worn rheostat card inside the sending unit.
- Before dropping the tank, wiggle-test the connector on top of the pump module and check ground continuity to chassis (under 0.1 ohm).
- Expensive misdiagnosis: replacing the entire fuel pump assembly when only the level sender card is bad, or chasing EVAP codes that share the same module connector.

- 2008-2016Chrysler Town & Country and Dodge Grand Caravan with the saddle-style tank use a transfer pump and two float arms tied together; the primary float pivot wears a flat into the resistor card around the 3/8-tank position, causing the gauge to stick and P0461 to set after a long highway run.
- 2007-2013Chevrolet Silverado and GMC Sierra 1500 with the 5.3L commonly fail the sender card from sulfur-fouled contacts, fixed by AC Delco SK1422 sender alone rather than the full module.
- 2004-2010Ford F-150 with the in-tank module sees the float arm bind on the bucket housing after pump replacement using off-brand kits.
- 2005-2012Nissan Frontier and Xterra have a TSB for the level sensor harness chafing on the frame rail just forward of the tank strap.

P0461 — frequently asked
What does a P0461 code mean?
Fuel level readings out of plausible range.
What causes a P0461 code?
Common causes: Bad sender; Corroded contacts.
What are the symptoms of a P0461 code?
Typical symptoms: Fuel gauge sticky.
Is it safe to drive with a P0461 code?
Only if running normally. A short trip to a shop may be reasonable if the light is steady and the car runs normally. Stop safely for a flashing light, severe shaking, overheating, loss of power, or another urgent warning. The code alone cannot confirm safety. Estimated repair: $300-$800.
How do I diagnose a P0461 code?
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
