Causes of Inaccurate Fuel Gauge and Tips to Overcome It

An inaccurate fuel gauge can lead to quite serious problems if not addressed immediately. This is because the car can break down due to running out of fuel. So why does this happen? What are the causes and how can it be resolved? For more details, let’s take a look at the following review.

Causes of Inaccurate Car Fuel Gauge

There are several factors that cause the car fuel gauge to be inaccurate. Here are the complete causes.

1. Dead battery

An inaccurate car fuel gauge is usually caused by a dead battery condition. As is known, the battery is a component that supplies and stores electrical energy. This energy will then be distributed to all car components that require electrical power. If this component has problems, then electrical energy cannot be distributed to the car's electrical components, including the car fuel gauge.

2. Broken speedometer

Damage to the car's speedometer can also interfere with the performance of the car fuel gauge, resulting in less accurate data.

3. Damaged fuel tank

A damaged fuel tank due to corrosion, leaks, or dents from impacts can also cause the fuel gauge to become inaccurate.

4. Tank often empty

The habit of delaying refueling until running out of fuel can also cause the fuel gauge to be inaccurate. This is because a tank that is often empty can create water vapor, which can cause the tank walls to rust over time.

5. Damaged cables

An inaccurate fuel gauge can also be caused by damaged cables. This damage is usually caused by electrical short circuits or frayed cables.

6. Problematic fuel float

The next cause is also due to a problematic fuel float. If this component is damaged, the float cannot rise when the fuel tank is nearly full.

7. Damaged fuel sensor component

Damage to the fuel sensor component also causes the sensor to be unable to convey information accurately to the fuel gauge.

8. Old car age

The age of an old car will affect the health condition of the components inside the car, including the fuel gauge.

Tips for Dealing with an Inaccurate Fuel Gauge

To address an inaccurate fuel gauge, you need to follow some of the tips below.

1. Check and repair all damaged fuel system components

The first tip is to check all components of the fuel system, starting from the fuel sensor, fuel float, connected wiring installation, to the fuel tank. Ensure that these components are not problematic. If there are issues, immediately make repairs or replace damaged components with new ones.

2. Check and repair all car electrical system components

The second tip is to check all components of the car's electrical system, starting from the battery condition, connected electrical wires, to the speedometer. Immediately replace with new components if these components are damaged.

3. Refuel immediately when the fuel gauge needle approaches “E”

The third tip is to not let your fuel tank run empty. Refuel immediately when the fuel gauge needle is close to the “E” mark. This can prevent corrosion in the tank and extend the lifespan of other components such as the fuel float, fuel sensor, battery, and speedometer.

4. Perform regular and periodic servicing at an authorized workshop

The fourth tip is to regularly service your car according to the specified service schedule. By servicing regularly, you can know the condition of your car's components and whether repairs or replacements are needed. This way, the wear and tear of the car components can be extended. Make sure to service at an authorized workshop like Daihatsu's official workshop to keep your car in optimal condition.
