2005 Chevy Malibu Gas Gauge Not Working

How do you reset the fuel gauge on a Chevy Malibu?

Each odometer works independently, so you can keep track of two different distances. Switch between them and the odometer by repeatedly pressing and releasing the reset button. To reset a trip odometer, display it, then press and hold the reset button until the odometer clears to zero. via

What would cause gas gauge not to work?

Depending on the location of the fault, the fuel sender may not have a source voltage, the gas gauge may have no fuel sender voltage, or the ground for either one may be interrupted. Loose connections and corrosion can also cause problems, particularly at the Fuel Pump Module, which is usually exposed to the elements. via

What does it mean when the fuel gauge needle suddenly drops?

Ray: Actually, you probably just have a faulty gas tank sending unit. There's a float in your gas tank that floats down as the fuel level drops. As the float goes down, the metal contact attached to it slides down a variable resistor. And the contact's point on that resistor tells your gas gauge how much fuel is left. via

What controls the fuel gauge?

The fuel sending unit has a float arm that sits in the liquid gas. When that arm moves up and down, it changes the resistance to ground on a variable resistor. That resistance is then translated and sent through the car's wiring and electronics to determine where the needle or digital gauge is positioned. via

Why is my gas gauge reading backwards?

Your car's fuel gauge functions by measuring the level of fuel in your tank. The lower the level of fuel, the higher the resistance of your sender unit. This means that less electricity passes through your Gauge and it shows a seemingly backward reading (empty on a full tank). Don't worry, this is normal. via

How do you change a fuel sending unit?

Remove the screws that hold the sending unit to the tank and take it out. Next, remove the three wires on the back of the old gauge. One wire goes to the center pin on the tank sending unit, one goes to ground, and the third connects to a 12-volt source, normally the ignition switch. Remove the fuel gauge. via

Why does my fuel gauge stay on empty?

A fuel gauge that only reads empty may be caused by the float separating from the arm, which causes the rest of the components in the fuel sending unit to stop completely. In some cases, a faulty resistor can also cause the gauge to read empty by restricting the signal completely. via

What kind of sensor is a fuel level sensor?

Gill fuel level sensors use solid-state capacitive technology to detect the level of gasoline, petroleum, jet fuel and other fuel types and grades. Our range of fuel level sensors are designed to provide high accuracy and reliability in the harsh environments including temperature and vibration. via

How much does it cost to replace a gas floater?

Depending on the make and model of your car and the specific sender that you purchase, costs will run on average between $250 and $800. You can save a lot of money replacing this part yourself if you feel comfortable. via
