Gas Gauge | Delaware, OH

Running out of gas while driving can be downright dangerous. If your vehicle’s gas gauge isn’t functioning properly, it can give you inaccurate readings, which increases your chances of suddenly sputtering to a halt on a busy road. Here’s a quick look at why this happens, and how Chesrown Chevrolet Buick GMC can help you avoid it.

Why does this happen?

There are several possible reasons why a gas gauge might stop working. The most likely of these is a mechanical failure. The gas gauge is a delicate device with a lot of components that could potentially break. One of these is the sending unit, which can wear away over time due to friction with the variable resistor. If your gauge interprets the resulting voltage as coming from a dead sender, it could show your tank as being fuller than it really is.

If a circuit is damaged, an inaccurate amount of voltage may also give false readings. Loose connections, friction and water damage, and corrosion are also possible culprits. In rare cases, the entire gauge or instrument cluster might fail.
