Why is my fuel gauge not reading?

An inaccurate fuel tank reading is most commonly caused by the sending system which reads the fuel tank level and sends the reading to the gauge. Issues can also stem from a bad gauge, blown fuses, or corroded wiring. You can self-test all of these parts at home with a few tools.

Is there a fuse that controls the gas gauge?

The fuse box will either be located under the driver’s side dash or in the engine compartment, so consult your owners manual to pinpoint the location so you can replace the fuse.

Where is the fuel level sensor located?

The fuel gauge sensor is a sensor that is not seen very often. This is mainly due to the fact that it is not located near the engine under the hood, which is the area you inspect most often. This sensor is located inside the fuel tank near the fuel pump.

What happens when a fuel level sensor goes bad?

A faulty fuel gauge sender may cause the gauge to suddenly change positions, or give an inaccurate reading. The gauge may appear to be at three quarters, and then only a few minutes later will change to half full, or vice versa the gauge may appear to be full, only to have the gauge climb higher a short while later.

How is the voltage of a gas gauge controlled?

Some gas gauges are directly controlled by voltage feedback from the sending unit, while others are controlled by the instrument cluster, which itself gets voltage information from the sending unit. The gas gauge is a relatively simple circuit, but its simplicity means each component is essential to its function.
