How to Fix Truck Fuel Gauge Reading Incorrectly

Resetting fuel gauges are some basic skills you should have as a truck owner. The fuel gauge is a significant component of your truck which gives you the actual amount of fuel in your tank. This component enables you to understand the rate at which your truck consumes fuel, and it will also help you to determine if the remaining fuel can sustain you up to the next filling station. In this guide, we will go through steps on how to fix the fuel gauge reading incorrectly.

Fuel Gauge Reading Incorrectly

A fuel gauge can be either digital or LCD, while others are analog. The fuel gauge has an indicator and sending units. When your truck’s fuel gauge is inaccurate, attribute it to a faulty sending unit. Here is an insight into what to do if your fuel gauge does not give accurate readings.

Steps To Follow When Resetting Fuel Gauge

Software or an electric malfunction makes your fuel gauge not give accurate readings of the fuel in your fuel tank. To solve the inaccurate fuel gauge reading problem, you have to revert it. The manufacturer’s guide usually gives the procedure for resetting your fuel gauge. But the reverting method is universal in all trucks. 

Follow the below steps to reset your fuel gauge. 

Turn On Your Ignition

Before performing this procedure, ensure your truck is parked on a plain surface and the handbrake is engaged. Please turn on the engine and let it run.

Put the Odometer Into ODO Mode

You will do this by pushing the trip/Odo button, the location of this button varies depending on the type of truck you have, but it is commonly located on the dashboard.

Turn the Ignition Off

You will have to perform this procedure several times, so you do not have to remove your key from the ignition. 

Press and Hold the Trip/Odo Button

While doing this, turn your keys on as you hold the button for around 2 seconds before releasing.

Press the Trip/Odo Button 3 times

Hold the Trip/Odo button on the third press for about 5 seconds. Release your hands as soon as the odometer displays the truck leveling information.

Press and Hold the Trip/Odo Button

At this point, only release your hand from the Trip/Odo button when the odometer says 1, which means that the resetting process has started. Keep holding the button as your fuel gauge resets. The resetting procedure comes to an end when the odometer moves to normal. At this point, you can release the Trip/Odo button and turn off your engine. 


Your truck fuel gauge is as equally important as other parts. You should ensure it is adequately maintained whenever it starts to malfunction. In a nutshell, it is necessary to know how to reset your fuel gauge.

When your fuel gauge functions correctly, you can know the exact quantity of fuel in your tank. A bad fuel gauge can give you wrong figures, and you might get stranded in a place where it is difficult to fuel your truck. 

To avoid inconveniences, consult your mechanic to help you fix a faulty fuel gauge. Troubleshooting fuel gauge issues on your own is cost-effective. You will only need to follow the above procedure.
