Low Fuel Light Still On Even After Pumped Fuel

asankabs · May 10, 2014

i have a toyota premio and 2 days ago i drove it till the low fuel indicator came up. today i pumped rs 500 amount of petrol but still the low fuel light is on. i can see a one bar in fuel gauge. also another strange thing is that the fuel efficiency value in the in the middle of the display (Km/L) does not change. any one know how to fix this?

also i really appreciate if some can post a link to english translated manual of this car(after 2010).

thanks

You are not just an idiot... u r a f**king idiot!

You pump 500 rupees of petrol and expect the low fuel indicator to go off???

and u had to open a thread to ask that????

*sighs* has a new premio and pumps 500 fuel.

kata kiyannada ithin mewa.

FFS you just pumped like 4 liters for like a 50ltr tank.
PUMP MORE PETROL

and i bet u cheaped out and pumped 92oct as well.. Good for you.

Typical .......

Are you serious or just joking? For the car user guide Try PM Sampath Gunasekera or there was a recent thread which contained those.

Hahahahahahahha this is hilarious! Anyway as others have solved your low fuel light indicator i'll solve the other one. Does the fuel economy reading say something like 10km/l? i think its changed to average fuel economy reading. There are 2 buttons on your instrument cluster one is to change whats shown on that display in the middle

Notice the two sticks? its one of those. i guess its the right side one

@asankabs - vehicle fuel level sensing mechanisms (old mechanical to new electronic based ones) has a threshold window (or more correctly a hysteresis threshold) when it comes to detecting and resetting the low level alarm. What this means is that let's say you get the alarm when you have only 5 Ltrs left in the tank. At this point if the mechanism is designed to reset the alarm with only additional 1 Ltr you would have a flickering alarm when you are on the move because movement of fuel inside that tank would move the float up and down to easily simulate the addition of 1 Ltr of fuel. Go and fill up at least 10 Ltrs to see if the alarm disappear. If it is still there then of course there could be a problem.

let me simplify this for you. i don't think anyone who has the revolutionary thinking pattern you do got what rumesh was trying to explain.

you sir, did the equivalent of throwing a hotdog down a hallway.

permit car?

Here's a simpler explanation

Now that you own a Premio, malli, you can no longer carry petrol in a coca cola mega bottle and pour it in to the petrol tank at traffic lights. Also you don't need to add 2T to the petrol. That should save you 30 bucks everytime you pump petrol.

guys i always pump oct 95. the reason that i pumped just rs 500 because i went to a rural area where the nearest oct 95 station is about 25Km away. i just wanted to go there so pumped rs 500 92oct.

you genius were very helpful here and im happy if i made you laugh

the average fuel economy won't reset even if i press the right side button. it only resets when i pump fuel but this time it didn't happen

A little context would've helped maybe?

Nothing would have happened if you pumped more of 92....

Well what a story asankabs you would be a good movie director directing movies with rivoting plots no one can foresee . I did not see that explanation coming. Anyhow just to improve my knowledge I have a particuar circumstance which I would like to be clarified. Thanks beforehand for any assistance.

One of my friends (quite a knowledgeable chap into automobiles according to my honest opinion) have aways told me that I must try to never get the petrol low indicator light on as it is not good for the petrol pump. He says that when the light comes on/ when your running on very low fuel levels then the Petrol pump does not get lubricated as a whole with Petrol. His view is that through time if you have a practice on running your vehicle on very low fuel the lubrication that the Petrol Pump needs would not happen reducing the life span of a petrol pump as the components of the Petrol Pump will wear off faster.

Over time, as sludge builds up

In the tank, this can happen. I've heard the same. The octane level however is not an indicator of the purity of the petrol. Just it's combustibility.

All in all it's a safe practice to pump before warning light comes on unless it's an unavoidable circumstance.

But OP's logic I can't understand. Because I'm yet to see a far off rural hidey-hole in our blessed nation that doesn't have a brand new Prius/vios/premio/axio etc.

Those cars must be pumping walas thel

Thanks. we really needed that laugh on a boring saturday evening/sunday morning.

So did u reach that shed 25km away and did u pump petrol? and did the low fuel indicator light go off?

Hoonigan · May 11, 2014

You must have got to that other pump 25Km away and topped up your tank before coming home right? Didn't your indicator clear at that point? Or did you immediately went online to open this thread at that rural pump? Must have mad cell reception for a rural area!

asanka BS indeed!

ruwds · May 11, 2014

Not only that, the fact only rs500 was pumped for a reason (unknown to the thread) and getting alarmed that the light did not go off when infact more fuel would turn off the light - simple logic.

Please check your car manual, It should state

i) total size of tank

ii) reserve fuel level when light turns on

These two facts should solve any further mystery's you may encounter with the fuel light (if you can work out the maths of course..)

I dont know if its the right or left button but one of those buttons will change the display to current fuel economy mode if thats what you want

Komisiripala · May 11, 2014

So did the light turn off when you topped up at the other station?

VVTi · May 11, 2014

I am yet to come across a situation where I wait till the Warning Light comes on to pump 95...when I knew that there will be no 95 for a few KMS... having said that I have pumped 95 and via credit card as far as Samanthurai and pothuvil.

So its all your fault for waiting till the tank ran dry. There are other wasy to squeeze out Kms out of your fuel, waiting till the tank run dry is not one of them

BTW, a replacement in-tank fuel pump for the 1NZFe is about 15k recon and 60k brand new....

few more 500 rupee fill ups and you will be opening a thread asking where to buy a pump.
