The error code P0461 can be defined as Fuel Level Sensor “A” Circuit Range / Performance. The Fuel Level Sensor tells the engine control module (PCM) how much fuel is in the fuel tank.
When the PCM detects an irrational signal from the fuel level sensor, it will set code P0461.
The Fuel Level Sensor may be part of the fuel pump.
What Does Code P0461 Mean?
The P0461 code means that the car’s computer has detected a discrepancy between what the fuel gauge reads and the actual amount of fuel in the tank.
Most fuel level sensors usually attach to the top of the fuel tank, although some designs sit within the fuel pump assembly.
Whatever its design, the sensor turns the mechanical fuel level into an electrical signal and sends it to the ECM or PCM.
The computer uses the sensor’s readings to monitor just how much fuel remains in the tank, keep track of fuel consumption, and adjust engine performance for the best fuel economy.
The PCM checks the voltage of the electrical signals sent by the fuel level sensor. If the voltage doesn’t match the correct operating voltage recorded in the computer, the onboard diagnostics will log a P0461 code.
The computer also checks the voltage of the fuel level sensor’s signals when the driver turns the key on for the first time. If it notices any discrepancy in the voltage, the PCM will set a fuel level sensor code.

Potential Causes of a P0461 Code
Typically the causes for this code to set are:
- Open in the signal circuit to the FLS sensor – possible
- Short to voltage in the signal circuit to the FLS sensor- possible
- Short to ground in the signal circuit to the FLS sensor- possible
- Failed FLS Sensor / sensing arm stuck mechanically – likely
- Failed PCM – unlikely
What are the Common Symptoms of the P0461 Code?
It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0461 here:
Common Symptoms
You will experience one or more of the following symptoms depending on your model and make, as well as the reason for P0461 code.
- Fluctuation of fuel gauge
- Fuel gauge is either full or less empty
- The light of the check engine is on
- The warning light of the Low Fuel will flash / on even if the tank is full
How to Fix P0461 Code?
Use these tips to fix a P0455 code accurately:
- Fuel Level Sensor – A broken or damaged Fuel Level Sensor need immediate fixation to avoid trouble in your engine system.
- Fuel Tank – Is your fuel tank damaged? Are you looking to replace them? Then you are at the right place as Parts Avatar offers it as best price.
- Fuel Pump – By replacing your faulty fuel pump, you can overcome this P0461 error code.
- Fuel Level Gauge – Get the right replacement part of fuel gauge for your vehicle from Parts avatar and avoid this error.
- Fuel Level Sensor harness – You can overcome the P0461 error code by Changing of fixing the joints of the fuel level sensor.
- Powertrain Control Module – Faulty or damaged Powertrain Control Module has to be replaced or repaired quickly.
How Much Does It Cost to Fix a p0461 Code?
A P0461 code repair typically costs between $200 and $500.
Depending on the vehicle make and model, with the primary cost factor being the labor involved to access and replace the faulty fuel level sensor within the fuel tank.
