FUEL GAUGE LIGHT ON 2005 TOYOTA PRADO 3L TURBO DIESEL???

fill the tanks completely and see if the light goes out. The tanks on the Prado automatically 'switchover' when the main tank is empty, the needle returns to the full position because the tank you have switched is full.

You may not have enough fuel in it to click it over to the main.

thats exactly it, you'll need to make sure you have more than 90L in there and I suggest if you are only putting 50L in at a time you are probably not putting enough in. You will notice if you have filled it up enough to use the 2nd tank the needle will go down to 1/2 full and then flick back up to full and the 90L light will come on.

Hi Just Goin

If you have read the owners manual, you should be aware the 90 litre light will be on continuously until you have more that half a tank of fuel - over 90 litres in total capacity.

When on trips and when you are using a good amount of fuel, this is how our fuel gauge works.

With a completely tank full of fuel, the fuel gauge will work as normal until around the half empty mark, which at that this point the needle will go back to the full position and then the 90 litre green lamp will come on, indication that you now have 90 litres of fuel or less available to use. From this point on the needle will drop as normal and show you just how much fuel is left in the tank, and the green 90 litre light will only go out when you put more than 90 litres of fuel back into your vehicle.

We have found the gauge to be reasonably accurate and on one of our remote desert trips, when where there was no ability to purchase any fuel, we arrived into Laverton and proceeded to put 175 litres of diesel into our Prado, which was a very expensive fill up. For this very reason, we always have a full tank of fuel at all times, and this stops the initial big drain on the wallet.

I hope this helps you out.


Cheers

If the fuel tanks in the Prado are nearly empty and you put in 100ltrs not all of it will go into the main tank. Probably 50ltrs will go into the main tank and 50ltrs into the second tank. This will not allow the the 90ltr light to go out. Go to a Petrol Station and fillup and I'm sure the light will go out. It will not come back on until you have used all the fuel in the main tank.

The 2005 120 actually draws all its fuel from the front tank. There is no "switchover" from the sub to main per se. What happens is the fuel is constantly transferred from the sub tank to the main via a jet pump, keeping it full until the sub is empty.

I'm not quite sure how the gauge logic works, but I imagine it's something to do with either the fuel senders or float switches controlling the 90 light, etc.
