Mileage Not Showing On Dashboard – Signs, Causes, and Fixes

Mileage not showing on the dashboard is a common problem experienced by car owners.

It can range from inconvenient to dangerous, as it can lead to inaccurate readings for important functions such as fuel consumption and oil changes.

Fortunately, there are some signs, causes, and fixes that you can use to diagnose and address this issue.

In this article, we’ll look at the common causes of mileage not showing on the dashboard, as well as tips to help you get your car back up and running.

Key Takeaway

• An odometer works by counting the revolutions of the vehicle’s drive train, which are then translated into distance traveled using the known circumference of the wheel and tire combination.
• Mileage may not show on the dashboard due to a variety of issues including a defective odometer, cracked solder joints, faulty dashboard lights, a dirty cluster, a dead digital display, or a defective car speed sensor.

How Does The Odometer Work?

An odometer primarily works by counting the rotations of the vehicle’s wheels and then multiplying it by the circumference of the tire to calculate the distance traveled.

In mechanical odometers, this is done through a flexible cable made from a tightly wound spring that turns the odometer.

In digital odometers, electronic signals are used to record wheel rotations and display the distance on the instrument cluster or dashboard.

The information is presented to the driver in terms of kilometers or miles.

What Causes Mileage Not To Show On The Dashboard

Here is what causes mileage not to show on the dashboard:

Faulty Odometer

A faulty or defective odometer is a common reason why mileage may not display on the dashboard. If the odometer malfunctions, it may fail to record and display the vehicle’s mileage accurately.

Cracked Solder Joints

Cracked solder joints can also cause mileage not to show on the dashboard. These joints are responsible for transmitting electrical signals; if they crack, the signals may get disrupted, leading to the dashboard not displaying mileage.

Dirty Cluster

The cluster, which houses the speedometer, tachometer, and odometer, may get dirty over time. This dirt can obstruct the visibility of the odometer reading or even interfere with its functioning, causing mileage not to show.

Faulty Dashboard Lights

Dashboard lights illuminate the instrument panel, including the odometer. If these lights are faulty, it may become difficult or impossible to see the odometer reading, especially in low-light conditions.

Dead Digital Display

In some modern vehicles equipped with digital odometers, a dead digital display could cause mileage not to show. This means the screen that displays the mileage has stopped working, perhaps due to a blown fuse or other electrical issue.

Faulty Car Speed Sensor

The car speed sensor plays a vital role in feeding speed data to the odometer. If this sensor is faulty, it may lead to incorrect or no readings being displayed on the odometer.

Faulty Wiring or Cables

Faulty wiring or cables can disrupt the transmission of signals from the car’s moving parts to the odometer, causing the mileage not to show on the dashboard.

Cruise Control Enabled

In some vehicles, when cruise control is enabled, the odometer reading might be hidden to show the target speed of cruise control. If cruise control is enabled but not set, this might result in a blank space where the odometer reading usually appears.

Signs That Your Odometer Is Not Working

• The odometer display is blank or illegible.
• The odometer reading doesn’t change even after you’ve driven a significant distance.
• There are discrepancies between the mileage recorded on service records and the reading on the odometer.
• The trip meter (which records the distance traveled in a single trip) doesn’t reset or change.
• There are signs of tampering, such as loose screws or misaligned numbers.
• The check engine light or other warning lights related to the vehicle’s electronics system are on.
• The speedometer is not working correctly, as it often shares a connection with the odometer.
• You notice erratic behavior of other gauges on the dashboard, which could indicate an underlying electrical issue affecting the odometer.

Where Is The Mileage Located In a Car?

The mileage of a car is typically displayed on the odometer, which is located within the vehicle’s dashboard.

The dashboard is the control panel located directly ahead of a vehicle’s driver, displaying instrumentation and controls for the vehicle’s operation.

In modern cars, the odometer is usually part of a digital or analog display that also includes the speedometer (showing the current speed of the vehicle), and other important vehicle status indicators.

The exact location can vary depending on the make and model of the vehicle, but it is generally centrally located where the driver can easily see it.

Is There a Fuse For The Odometer?

Yes, there is typically a fuse for the odometer in most vehicles. The odometer is an electronic component and it, along with other parts of the dashboard, is often protected by a fuse.

This fuse is usually located in the fuse box, which can be found either under the dashboard or in the engine compartment, depending on the make and model of the vehicle.

If the odometer stops functioning, one of the first troubleshooting steps is to check this fuse and replace it if necessary.

However, the exact location and specification of the fuse can vary greatly from one vehicle to another, so it’s best to consult the vehicle’s manual or a professional mechanic for specifics.

How Much Does It Cost To Replace an Odometer?
