Why does my fuel gauge work sometimes?
Alternatively the gauge may read F and E all the time regardless of how much fuel you actually have. In some cases the fuel gauge will randomly read E and this can be fixed simply by turning your car on and then back on. This is likely caused by a wiring or sending unit issue.
How do you reset the fuel gauge on a car?
How to Reset a Fuel Gauge
- Turn the ignition switch to the “On” position.
- Press the “Odo/Trip” button until the odometer is put into “ODO” mode.
- Turn off the ignition.
- Press and hold the “Odo/Trip” button.
- Release the “Odo/Trip” button.
What are the symptoms of a bad fuel 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.

What causes fuel gauge to fluctuate?
A fuel gauge displays that fluctuates between empty and full may be due to a mechanical failure. The fuel sending unit float arm may ‘stick’ at certain levels, and fall back into place either naturally or with help from vehicle movement. Once the float arm falls back into place, the fuel gauge becomes accurate again.
Is there a fuse for gas gauge?
As mentioned, the fuel gauge fuse is most likely the same as the fuse that all of your other instruments use. This means that this fuse could be located in the fuse box that’s under the driver’s side of the dashboard.
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.
How do I test my fuel gauge?
Turn on the engine’s ignition and probe with a multimeter between the ground and the positive terminal on the back of the gauge; it should be marked with a “+” or an “I.” If there is no voltage then the fault is in the ignition circuit—and the gauge is probably good.
Why does my gas gauge keep going up and down?
What will cause the fuel gauge not to work?
Fuel Gauge Reading Incorrectly: What Went Wrong? Sending Unit Failure. The most common reason for a fuel gauge to not work. Problems with the Circuit. Depending on the source of the trouble, there could be a voltage problem in the fuel sender, causing the gauge to receive no voltage response Gas Gauge Failure. A less common but not outright impossible reason. Non-Functioning Instrument Cluster.
What’s causing my gas gauge to not work?
Sending Unit Failure is the most-common cause of a gas gauge not working. Circuit Problems can cause the gas gauge to stop functioning normally. Gas Gauge Failure is less common, but still a possible issue. Instrument Cluster Failure is the least common, and likely the most expensive problem to fix.
Do I still have a fuel gauge problem?
If the gauge continues to read empty, you most likely have a faulty fuel gauge that needs to be replaced. After replacing the fuel gauge, if there is still a problem with the fuel reading, consult a mechanic. Ensure there is fuel in the tank before beginning these steps.
Why is your fuel gauge always stuck on full?
Fuel gauge stuck on full Another, less common, symptom of an issue with the fuel gauge sender is a fuel gauge that is stuck on full. A faulty fuel gauge resistor can send a bad signal to the instrument cluster which can cause the gauge to permanently read full.
