How to Fix Gas Gauge: Are You Actually Running Out of Fuel?
Posted: Fri Feb 16, 2024 8:14 pm
Even if you don’t have the slightest idea about the internal mechanics of vehicles, you know about the fuel gauge. It’s one of the basic concerns when you own a car. As the gas gauge lets you know when your car needs refueling, keeping an eye on it is essential. After all, you don’t want your car to stop in the middle of a highway with no workshop for miles. So, learning how to fix gas gauge can be handy.
How Does It Work?
The gas gauge system is basically differentiated into three parts: sender, gauge, and circuit. A fault in any of these parts will cause a failure in the system.
Generally, the fuel sending unit is a part of the fuel pump module. That’s a combination of parts including the fuel strainer, fuel pump, fuel float, and a fuel filter. The fuel sender modifies the ignition circuit.
The gas gauge circuit contacts the sending unit, gas gauge, battery, and ground. Most modern sending units have a ground connection to their electrical system whereas a few older models were grounded to the frame or body.
To know how to fix a gas gauge, you must first learn how to identify the signs that the gas gauge is broken. Not so surprisingly, the signs are pretty straightforward. If the needle of the sensor moves much quicker than you feel your car is burning gas or just ticks erratically, there is an issue in the gas gauge system.
Fortunately for the newbie car owner, the gas gauge is one of the simpler circuits of a vehicle. While simplicity means you don’t need a degree to handle the system, it also means that the components are crucial for the functionalities.
An instrument cluster failure is the rarest and most expensive-to-fix issue. Most modern instrument clusters feature fully integrated circuits, sometimes devoid of replaceable parts. You have to replace the whole unit if the gas gauge malfunctions as part of these clusters.
How to Fix Fuel Gauge
As we said, self-diagnosis of such problems is pretty easy. You only need a handful of tools: a digital multimeter (DMM), an electrical wiring diagram (EWD), and a set of basic tools. Then, run the following tests to identify the source of the problems.
Use a Multimeter to Test the Gauge
There is, in fact, a fuse for the fuel gauge. Any part of your vehicle that needs electricity to run will have some form of contact with the fuse boxes inside the vehicle. So, a car has multiple fuse boxes. Traditionally, one is located under the steering column. Most vehicles also have a fuse box under the hood.
Yes, you can certainly drive your car even when it has a bad gas gauge. However, we don’t recommend it at all, unless you’re very diligent about filling your car up regularly and tracking gas consumption.
Just because the gas gauge is broken you don’t have to worry about being stranded on the roadside with an empty gas tank. All you need to know is how to take a reading from the broken state. So if you’re delaying on how to fix gas gauge, this is a doable alternative.
The price is going to vary based on what issue you’re there to get fixed. A simple issue associated with a fuse could be solved for as cheap as $10 because all you will need is a new fuse. Or, if you have to replace the entire fuel gauge sender, expect to pay up to $800 after labor.
