Error Code P0461: What It Means & What To Do?

<<See All OBD Codes

The engine control module (PCM) gets information from the Fuel level Sensor regarding the amount of fuel present in the fuel tank. The P0461 code will be set by the PCM when it detects an irrational signal from the fuel level sensor. The fuel pump may contain the Fuel level Sensor.

The level of fuel present in the vehicle’s tank is informed in terms of voltage to the PCM. A difference between the fuel level and its report to the PCM is referred to as P0461 error code. P0461 code will be recorded in the onboard computer of the vehicle, only if the voltage level received by the PCM from the fuel level gauge, is not similar to the actual quantity of fuel in the tank. This error code can also be stated if the input voltage level surpasses the maximum factory level.

What causes this problem with the Fuel Level Sensor Circuit Range/Performance?

• Broken Fuel Level Sensor
• Fuel Level Sensor joint is exposed or shorted
• Reduced electrical connection to Fuel Level Sensor circuit
• Broken combination meter

1. Fuel Level Sensor - A broken or damaged Fuel Level Sensor need immediate fixation to avoid trouble in your engine system.
2. 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.
3. Fuel Pump - By replacing your faulty fuel pump, you can overcome this P0461 error code.
4. Fuel Level Gauge - Get the right replacement part of fuel gauge for your vehicle from Parts avatar and avoid this error.
5. Fuel Level Sensor harness - You can overcome the P0461 error code by Changing of fixing the joints of the fuel level sensor.
6. Powertrain Control Module - Faulty or damaged Powertrain Control Module has to be replaced or repaired quickly.

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

Replacing the fuel gauge or the instrument cluster is the common repair for P0461 code. However, other repair works may be essential, which includes the following:

• Changing or fixing a damaged wiring joint
• Changing the broken fuel tank grounding wire or strap
• Changing the damaged fuel tank
• Replacement of a faulty PCM or fuel level controller which is rare

Here are some steps which you should follow in order to diagnose this P0461 fault code:

• Firstly, the mechanic will connect an OBD-II scanner to the communication port of the car that is present under the dash of the driver side. The codes are read, and cleared. Now test drive the car to see if the codes return.
• Next, the mechanic will keep the key on and then detach the fuel sending unit connector and ground wire, to check if the fuel gauge moves either to full or empty. If the gauge performs well, then the mechanic will start diagnosing the rest of the system. If the gauge does not move, then you have to replace the cluster. Check for circuitry by removing the cluster and see if there are any damages or corrosion to the wiring.
• If the gauge moves as stated by the mechanic, he will then check for damages to the fuel sending sensors wiring joints and other networks. The mechanic will also check for the conditioning of the fuel tank grounding strap and as well as for corrosion and clean them, as it can also give rise to P0461 code.

Common Mistakes When Diagnosing the P0461 Code

• Fault in the Fuel pump
• Fault in the Powertrain Control Module (PCM)
• Electric wiring issues
