P0461 — Fuel Level Sensor A Circuit Range/Performance
Low severityWhat it means
P0461 is stored when the engine control unit sees a fault involving the fuel level sensor circuit. The fuel level sensor reports how much fuel is in the tank; besides the gauge, the control unit uses it for some EVAP leak tests. A “range/performance” fault means the value is present but implausible — it does not agree with other sensors or expected conditions.
Common symptoms
- Readings that drift or disagree with related sensors
- Fuel gauge reading wrong or stuck
- Check engine light
- EVAP monitor not completing
Likely causes
- Drifting, contaminated or aged sensor
- A mechanical issue skewing the reading
- A worn fuel level sender in the tank
- A wiring or connector fault
What to check first
- Cross-check the reading against related sensors in live data on a cold start
- Watch the fuel level reading in live data as the tank empties
- Inspect the sender wiring and connector
Can you keep driving?
Safe to drive; the main inconvenience is an unreliable fuel gauge, so keep an eye on your mileage.
Frequently asked questions
What is the most common cause of P0461?
The most likely cause is: Drifting, contaminated or aged sensor. Several other faults can set P0461 as well, so confirm the real cause with live data and the checks above before replacing any parts.
Can I just clear P0461 and keep driving?
Clearing P0461 with an OBD2 scanner turns the warning light off, but if the underlying fault has not been repaired the code will usually come back within a few drive cycles. Fix the cause first, then clear the code to confirm the repair worked.
How serious is P0461?
P0461 is a low-severity code. It rarely affects how the car drives, but it is still worth fixing so the engine runs efficiently and passes an emissions test.
