Why would my gas gauge just stop working?
What Causes The Fuel Gauge Not To Work? 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.
How do you reset the fuel gauge on a Chevy Malibu?
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. The fuel gauge will register the approximate fuel level in the tank when the key is in the “ON” position.
How do I fix my gas gauge not working?
How do you fix an inaccurate fuel gauge?
- Turn the ignition on and off a few times, and observe if the needle on the fuel gauge moves.
- Test the grounding wire on the sending unit of the fuel tank.
- Disconnect the wiring connected to the sending unit of the fuel gauge and then look at the fuel gauge.
How do you diagnose a broken gas gauge?
Symptoms of a Malfunctioning Fuel Gauge
- Inconsistent Readings.
- Reads Low When Tank Is Full.
- Reads Full When Tank Is Empty.
- False low fuel light.
Is there a fuse for fuel 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.
How do I reset my gas gauge?
How to Reset a Fuel Gauge
- Turn the ignition switch to the “On” position.

- Turn off the ignition.
- Press and hold the “Odo/Trip” button.
- Release the “Odo/Trip” button.
How do you reset a gas gauge needle?
How do I reset my fuel level sensor?
Why is my fuel gauge not working properly?
The most common gauge problems are either a bad ground at the tank, or a sender problem. As with any electrical troubleshooting, it is best to check the fuse and all wiring connections are clean, tight and free of corrosion. The following process will require the ignition switch be in the “on” position for troubleshooting a fuel gauge issue.
What to do if your gas gauge reads lower than it should?
When the gauge reads lower than it should, check at the gauge by disconnecting the wiring from the tank unit. Turn the ignition on and if the needle reads full or above, the gauge unit is probably good and the tank unit or the wiring leading to it are probably the problem. Reconnect the tank unit wire to the gauge before proceeding.
Where is the gas gauge located on a Chevy truck?
The gas gauge, often located in the instrument cluster, consists of two small coils spaced 90 degrees apart with an armature and a needle placed at the intersection of the two coils. A dampener is also located on the armature to prevent excessive needle movement on rough roads.
What causes the gas gauge needle to move?
The variations in the amount of fuel in the tank cause the arm to move. This changes the resistance of the tank unit, changing the amount of current at the gauge unit coils, which in turn moves the needle located between the coils.
