P0461: Fuel level sensor circuit range/performance
The fuel level sender reports a level that does not match fuel use or hardly changes. Often a sticking float or a worn resistor track.
| Code | P0461 |
|---|---|
| System | Engine and transmission |
| Group | P04xx, Emissions control |
| Type | Generic: it means the same on every make |
| Can you keep driving? | With care |
What P0461 means
The ECU compares the level from the sender with how much fuel it reckons has been used. If the level does not drop as you drive, jumps suddenly or does not fit usage, it logs this code. The circuit is working electrically, but the reading is not believable.
Most common causes
- Worn patches on the sender’s resistor track
- Float rubbing, catching or filled with liquid
- Deformed tank restricting the float arm
- Connector with an intermittent poor contact
- Wrong sender fitted after a repair
Symptoms
- Gauge stuck in one area or dropping in steps
- Gauge changing suddenly on bends or hills
- Engine warning light on
Can you drive with P0461?
With care It does not affect the engine, but the gauge is not reliable. Fill up early and keep track of the miles covered.

How to check it
Note the live level with a full tank and check it every so often as you drive. If it stays stuck at one value and then drops sharply, the sender track is worn.
How to read and clear P0461 with Final OBD
Plug an OBD2 scanner in under the steering wheel, switch the ignition on and open Final OBD. Under Faults you’ll see P0461 with its description and whether it’s confirmed, pending or permanent.
If the engine stores it over standard OBD, with FREE you read this code with its explanation for nothing and clear it. With PRO you also read the faults of every control unit and clear them in all of them.
Clearing the code only turns the light off: if the cause is still there, it comes back. Clear it once it’s fixed, and not right before an inspection. It’s all in how to read and clear fault codes and in inspections and OBD.

How do you clear P0461?
With an OBD2 scanner and an app like Final OBD, which clears it for free if it’s stored by the engine control unit. But clearing it only turns the light off: if the cause isn’t fixed, P0461 comes back.
Read it on your car
Final OBD reads and clears engine faults through standard OBD for free, each one explained in plain English. With PRO it also reads the faults of every control unit, each make’s own codes included, and clears them in all of them.
