The fuel gauge system has two main components: a transmitter unit, which measures the amount of fuel in the tank, and the meter itself, which displays the amount of fuel for the driver. If the meter, transmitter, or the required wiring between them does not work properly, the fuel gauge may show incorrect data or simply do not work at all. There are some simple tests you can do to check if your fuel gauge is working:

1.
Ensure that all wiring connections (both on the back of the meter and on the measuring unit) are clean, sealed and free from dirt and corrosion. If you check the wiring on the back of the fuel gauge, you may have to go under the dashboard, remove the dashboard, or remove the sensor from the dashboard. The transmitter is located on the fuel tank and is available in many cars under the rear
seat or trunk. To do this, remove and raise the rear seat or trunk mat.

2.
Turn the contact on and off several times and check whether the needle is fully moving. If there is no movement, check the fuse. The fuse panel can be under the hood or under the dashboard. Each fuse must be marked with a current and digit or series of letters indicating which circuit protects the fuse. Refer to the maintenance manual to determine where the fuse panel is and which fuse controls the fuel gauge system. Replace the fuse if it is defective and check that the spare fuse has the correct amperage.

3.
Connect the jumper to the ignition switch and the connector on the back of the fuel gauge, and then turn on the car. If the meter is working now, replace the faulty wiring between the meter and the ignition switch.

4.
Ground the meter by soldering or cutting the end of the jumper to the meter ground terminal and the other end to the clean contact point on the car frame, and then turn on the car. If the meter starts to work, replace the ground wire of the faulty fuel gauge.

5.
Ground the transmitter block with the jumper using the method described in the previous step. The transmitter can be grounded by attaching the auxiliary wire to the outside of the fuel tank or the frame of the car. Replace the transmitter ground wire when the instrument starts.

6.
Disconnect the wire connecting the fuel gauge to the transmitter, and then turn on the car. If the fuel gauge indicates that it is full, it indicates a problem with the sensor or mechanism in the tank. If the meter continues to show a blank, you may have a faulty fuel gauge that needs to be replaced.

Points to note:

After replacing the fuel gauge, if a problem with the readings remains, contact a specialist.

Make sure there is fuel in the tank before you begin these steps.

Before touching live wires, disconnect the battery from the vehicle.

Nice one

Okay

No be those wey get moto dey check fuel gauge?

More like teaching a novice about practical steps to burn a car.

Oshey o Jare!

You are an ancient mechanic. Don't try this nonsense on modern cars you may kill the brain box. Use OBD II to diagnose it.

no mind them.

Great

Don't mind the quark mechanic.

Don't mind the quark , what is the function of OBD 2?

This is the problem with copy and paste.

This is exactly the challenge I am having right now. My gauge ain't working fine, I wouldn't know what the problem is.

It displays false reading.

Kind of annoying when you're trying to analyse the issue, and Kazeem just tells you, "Oga go buy fuel put".

it's as if, the more gadgets you have the more you stress yourself checking this and that. Somebody cannot drive car again without doing full engineering course?
Check which wire?

Abeg buy urself one bottle for this epic comment

Just don’t tell me that the car transporting buhari back to duara on Saturday is having fuel gauge problem,we will send an Atikulated Uber driver to pick him up.

Here’s the picture of the car

I thought it is something I can do on my own

I thought I'd see something spectacular. Well, good job OP

Obsolete practice. What about the cars with digital fuel gauges?

just fill your tank to the brim and see if the guage is not working

The Check Engine light and Vsc light on my rx300 just off by itself
Let's somebody shout hallelujah!

Ok
