inaccurate fuel gauge

[badabing82]

Hi Guys,

I have a 05 camry sportivo, since a alternator or battery change im unsure which one was the catalyst for the issue, the fuel guage is reading too high by about 1/8th of a tank.

So once its drops just below a 1/4 tank it has about an 1/8th left.

Is their a reset procedure or calibration procedure?

Any help would be great.

Regards

Dan

Is this guage an analogue one or digital?

No.

Is this a new issue? If so it may be a sender issue.

For the older analogue types, the test prodedure is described in various published links online. Also in my electronic service manual (for earlier vehicles).

I'm guessing yours is a digital one?

I would do a search online for a test procedure in that case, unless you already have a service manual for it.

Wow thanks for the fast replies.

Its non-digital gauge so analogue.

It's not a "new' issue but it certainly happend after a battery change / alternator change which was in the same week. I drove the car and got stuck on the side of the week after with the fuel gauge sitting between empty and 1/4. I thought maybe it was a computer issue

That's good news. There are several descriptions of the simple tests that can be done with analogue fuel guages. I did some recently.

Also, the needle on that type of guage is usually a press fit onto the spindle. At least mine is; I only just worked on it a short while ago while fitting a tacho to the dash.

What this means is that the needle can be pulled off and replaced onto the spindle in another position. Fit, test using test procedures above. If you can't find the description(s) quickly, let us know and I find them for you.

Where have you gone Dan? I've logged on each day only to find you have not replied for four days. I would like to see you resolve this and get it fixed.

Here is the test procedure for an analogue type guage:

I have a 2004 Camry Sportivo and have similar issues with the fuel guage reading about a quarter tank too high. It shows full at full then at 3/4 i usually fill up with approx 32 litres, When the guage is is at a quarter, I have about 6 litres left.

Appreciate any advice, information on what I can do

Is your guage an analogue one or digital?

If analogue, the tests are simple and can be found on a DIY site on the net. Or I can describe if you want.

fix to this was opening the dash and forcing the needle to another “calibration” not sure why or how this happend. A short time after i sold the camry and got a mazda 3, but i have a 2017 corolla now. def more refined!
