Recently, the fuel gauge on our 2012 Sonata began to malfunction. We first noticed it when it said that we were out of petrol even though my wife had filled the tank earlier in the day. When we went to purchase extra gas, it only required a few liters. When it first happened, we believed it to be some kind of oddity, but now it’s happening more frequently. We took it to the dealer twice to have them look at it, and both times they said they couldn’t reproduce the issue and charged us a diagnostic fee. She also showed them the numerous videos she had made of everything taking place. Anyone here experienced the same problem? Here is a link to the video on YouTube so you can watch.
On the Hyundai, all other gauges function, but the fuel gauge won’t work and constantly displays empty. How can I resolve this issue?
Before checking the gas tank, turn the ignition on and off numerous times as a blown fuse is typically to blame for fuel gauge issues. If the gauge doesn’t move, check your fuse box and use your repair manual to locate the fuse. If the link is damaged or broken, replace the fuse. Next, check the gauge’s wire connections to ensure they are clean and attached. the “off” position on the ignition switch. Connect a jumper cable’s one end to the terminal located behind the fuel gauge. The ignition terminal should receive the other end. If your car’s gas gauge indicates that the tank is full but it isn’t, replace the sender unit in the gas tank. If the needle doesn’t work, get a new fuel gauge.
Check the fuel sender sweep
Fuel lines and pump connectors should be disconnected. From the tank, remove the whole fuel pump mechanism. Watch the DVOM measurements while raising the float arm. A rise or decline in the reading should be visible without any dropouts. Take a reading while the arm is completely extended and then compare it to the specifications. Replace the fuel sender if they are not on. If they are in good shape, look at the cabling and connector between the body control module and the gasoline sender.
How do you reset the Hyundai fuel gauge?
Resetting a Fuel Gauge the “On” position on the ignition switch. Once the odometer is in “ODO” mode, press the “Odo/Trip” button. OFFSET the ignition. Long-press the “Odo/Trip” button. “Odo/Trip” button should be released.
Why is my fuel gauge permanently at zero?
Fuel gauge is stuck at zero. A fuel gauge sender that is malfunctioning frequently displays another common symptom: an empty gauge. The gasoline gauge could fail and get stuck on empty if the float accidentally snaps or separates from the arm. The gauge may potentially display empty due to a broken resistor.
What is in charge of the fuel gauge?
The gasoline tank and transmitting unit’s operation can be seen visually thanks to the gas gauge in the instrument cluster. While other gas gauges are controlled by the instrument cluster, which in turn receives voltage information from the sending unit, other gas gauges are directly controlled by voltage feedback from the sending unit.
The fuel gauge is controlled by what sensor?
All autos have a fuel level sensor (FLS) that displays the fuel level. Fuel level can be determined using a variety of techniques, including capacitive, discrete resistors, resistive film, and ultrasonic. For this application, resistive-based sensors are most frequently utilized. The mechanical connection between these sensors and a float, which changes height in response to fuel level, is strong. The sensor’s resistance varies as the float moves. This sensor is a component of the fuel gauge display circuit’s current balancing circuit, which normally comprises of coils for actuating the display needle. The position of the needle varies proportionally to the current flowing through the coil as the resistance of the fuel sensor varies. In Figure 1, a typical resistor-based FLS is displayed.
The wear and tear of the sensor caused by the sliding contact inside the sensor parts is a drawback of resistive contact-based sensors. The sensor life is shortened as a result of wear and tear.
This study discusses how to employ Hall-based sensor ICs for FLS applications that require non-contact sensing.
Why isn’t my fuel gauge showing the correct amount?
Five fuel gauge system components that may be damaged and require repair or replacement can cause the fuel gauge to malfunction. The transmitting mechanism, which reads the fuel tank level and delivers the reading to the gauge, is most frequently to blame for an erroneous gasoline tank reading.
A broken gauge, blown fuses, or damaged wiring can also cause problems. With a few tools, you can test each of these components on your own at home. Check out the comprehensive step-by-step guide at the conclusion of this post if you’re interested in accomplishing this.
How can I turn off the low fuel indicator?
Your low fuel warning light ought to go out once you fill up at the closest gas station.

Your fuel level sensor may need to be serviced if your light remains on even when your gasoline tank is full. Consider utilizing higher grade fuel. Lower grades may contain traces of water or have additional contaminants, which could harm your sensor.
Taking your automobile to a repair might be a smart idea if you are still experiencing issues. Your mechanic will examine your sensor for flaws and clean or replace the sensor as necessary. Your fuel tank may also be inspected for flaws by your mechanic. A
Depending on the make and model of your car, replacing your fuel sensor could run you $200 to $300.

How can I tell whether the sending unit or fuel gauge is malfunctioning?
Although less frequently, the gauge can display full when the sender is malfunctioning. Instead, a defective resistor is frequently the cause of a fuel gauge that is locked at full.
The instrument panel receives the incorrect signal from the resistor, which causes it to indicate that the tank is full. It’s possible that the transmitter is to blame if the resistor isn’t the problem.
How is a fuel tank calibrated?
Process for calibrating a gasoline tank with the goal of producing a calibration table that maps the LLS-HD fuel level code to volume.
The procedure of calibrating a fuel tank involves filling the tank incrementally from “Empty” to “Full,” with a set amount of fuel for each stage, while also correcting the mapping between the calibration table’s level code and volume.
Additionally, this procedure can be modified to calibrate with “Full” to “Empty” draining.
calibration of the fuel tank with a single LLS-HD installed:
1. Drain the tank of fuel.
2. Use the Omnicomm UNU-USB adapter to connect the LLS-HD to the PC in accordance with the plan.
3. Open the Omnicomm Configurator program. From the “Operation mode” drop-down menu, select “Fuel tank calibration.”
4. Click “Add a sensor” if the “Sensor 1” column is not visible. Choose the type of sensor. During initial configuration, choose the “Sensor network address” setting.
5. Enter litres for the “Interval between the calibration points.”
Use a gauge tank or a fuel flow counter with a predefined volume for each step during refueling.
6. Click the option to “Start/Continue the Calibration.”
7. Add fuel to the specified “Interval between calibration points” quantity.
8. Select “Add a row” on the menu.
9. Click “Add a row” to add a row.
10. Continue carrying out steps 7, 8, and 9 until the fuel tank is full. The minimum number of steps for gasoline tank calibration is 20, according to Omnicomm.
11. Select “Fimish the calibration.”
12. Using the “Export” button on the Terminal, LLS-HD, Omnicomm Online, or fuel tank calibration file (.ctb), save the calibration table.
In the event that a fuel tank has more than one LLS-HD installed, follow the calibration method just as you would for a single LLS-HD, but before calibration begins, all sensors must be uploaded to the Omnicomm configurator. All installed sensors will all be calibrated concurrently for fuel tanks. With KTZ-splitter, multiple LLS-HD devices can be connected to the PC simultaneously.
Is repairing a gas gauge expensive?
I discovered I was running low on gas as I was traveling down the street. I assumed the gauge was malfunctioning at the petrol station because it only allowed me to put in a few gallons. How much does a car gas gauge repair typically run?
In less than two minutes, find out if your auto insurance is being overcharged.
Although having a damaged gas gauge is inconvenient, it is unquestionably a fixable problem! Depending on the model of the automobile, you might get the part for between $50 and $200 to fix the gas gauge for the least amount of money.
If you decide to visit a repair facility, budget $200 to $300 for labor if you purchase the new gauge on your own. According to some reports, you may have to pay between $300 and $1,000 at a dealership depending on the type and model of your car.
You should always check your insurance to see if your extended warranty covers this.
However, there are other ways to cut costs on the repair if your warranty does not cover it. Try using the Jerry app to see whether you can save money on your auto insurance—it will bring you tailored quotes from leading companies, leaving you with only the task of selecting the strategy that will work best for you!
Is there a fuse in the fuel gauge?
A fuse may be at blame, especially if you are having problems with multiple gauges on your car. Make careful you replace the instrument panel fuse if it has blown.
What location does the fuel level sensor have?
The fuel level sensor has historically been a component inside the fuel tank with a resistive strip and a wiper contact that slides on that strip (as on older cars when the ECM/PCM doesn’t monitor fuel level).
What is the fuel sensor code?
We’ve teamed up with RepairPal to provide recommendations for reliable stores nearby. Enter your information to find certified shops in your area that provide upfront estimates, guaranteed fair pricing, and a warranty with a minimum of 12 months and 12,000 miles.
The powertrain control module (PCM) of your car sets off the P0463 code when it notices that the fuel level sensor is reporting incorrect fuel levels. The PCM is informed of the fuel level by the fuel level sensor. The check engine light turns on as a result of this code because the fuel level sensor detects that there is more petrol in the tank than it can actually contain.
If the gauge is damaged, would the gas light still come on?
The gasoline gauge and the low fuel light are linked, thus if the gauge is broken, the low fuel light can also turn on. A malfunctioning fuel level sensor may be the cause of problems with the fuel gauge in the instrument cluster.
The low fuel indicator may flash needlessly due to issues with the fuel sensor. Though the sensor is malfunctioning, the fuel light may illuminate even if the gauge is functioning properly. However, you might not be able to rely on the accuracy of the fuel readings.
How much does a fuel level sensor replacement cost?
While parts are priced between $773 and $862, labor costs are predicted to range between $161 and $203. This range does not account for taxes and fees, your particular car, or your particular location.
