Exclamation Fuel Gauge Problem - Contessa & Esteem

Hi,

I've been having a problem with my fuel guage for a long time now.

The photo here shows the gauge when the tank is full.



I have checked the float and the guage for any problems, but all seems OK.

Can anyone help solve this please.

Thanks,
Falcon

Welcome to the club. My car's fuel guage worked fine for a long time. Now the needle just dosen't move up. I checked the fuse, the float, etc. and again, like your case, it seems to be fine. I'm taking it to the garage this week. Let's see what happens.

I use my odometer to know when to fill fuel.

Hi Aditya,

The Temperature gauge and the Fuel gauge are connected via the same supply line. There is a sort of thermal relay to limit the supply going to the Fuel gauge, so the Fuel gauge does not get pure DC, but pulsating DC.

If your temperature meter is working then supply is not a problem, it could just be a matter of cleaning the contacts of the bimetallic strip feeding the fuel gauge.

Do let me know what the findings are... It will at least give me a pointer as to what I have missed checking.

BTW which garage do you go to ?
I take it to National Garage at Milan Subway, Santacruz. Have not asked them about this fault as yet though...

Well, my meter is not totally dead, so as soon as it drops to quarter tank, I top it up...

And even at the quarter mark, the tank still holds about 20 litres of fuel!!!

It dosent move at all. It all started after i installed my new central locking . it had a ignition cutoff function which completly killed my battery as i did not know how to bypass it. The speedo meter is working fine but the temprature guage is not working as well, at times i see it climbing up but it stays below normal. I think its a bad fuse could you tell me how to check and which could be that fuse?????

Well i am also facing problem with my fuel gauge Type 1 esteem.
I had tried to repair the float winding, it worked fine for an year but again its gone bad.
Mechanic said to replace the kit i.e. Fuel pump and gauge float. Rs 6k new isnt it killing, dont we get the fuel gauge only?

Needles are working fine the problem rests at the tank end. What to do?

Dude, if the problem is inside the tank, he will advice you to change the whole fuel pump set. Cost 6k for original and nalla about 1.5-2k.
Mind it you dont get the fuel gauge seperate.
My suggestion would be to search for it at some junk ward.
Also donot leave the car at workshop.
There is a winding on a plastic pad like thing, on which the needle moves.
check if there is a cut in the winding, try to repair it.

So let’s understand how most fuel gauges and indicators work.
The gauge consists of two parts:
  • The sender unit
  • The indicator
The sending unit usually uses a float connected to a variable resistor. When the tank is full, the resistor is set to its low resistance value.

As the tank empties, the float drops and the slides a moving contact along the resistor, increasing its resistance, finally reaching its highest value when the tank is empty. In addition, when the resistance is at a certain point, it will also turn on a "low fuel" light on some vehicles.

The indicator unit on the instrument panel is measuring and displaying the amount of electrical current flowing through the sending unit. When the tank level is high and maximum current is flowing, the needle points to "F" indicating a full tank. When the tank is empty and the least current is flowing, the needle points to "E" indicating an empty tank.

The system is fail proof; a fault that opens the electrical circuit causes the indicator to show the tank as being empty rather than full.

Thus you have to start from your float assembly and check the resistor coil at the end of the float for any discontinuity in the coil. Also check all the wiring from the float assy. to the indicator and the ground wire.

Finally you can also eliminate the doubt in the meter by shorting the meter terminals and it will show a full tank and explain the meter is working.

All spares including the float assy. pump are available separately and can be replaced after identifying the cause of the problem.

Cheers
Mike
