Gas Gauge Indicator

yes, this sometimes happens. there is no way to know if the pump shut off early, or the gauge didn't register all the way. (which sometimes happens for unknown reason) don't try to add more as that can potentially cause damage. if you track your mpg's and fill up history, you usually have a pretty good idea of how many gallons it will take.

 

That happened to me as well the first few times that I went to fill up my fuel tank. Eventually the problem went away. My guess is that it's just how you hold the pump to refuel. If it's not in the right place, then the nozzle will click.

 

Your post implies that you were watching the gas gauge display WHILE pumping the gas.
If so, that's probably not a good thing to do.......as all electrical systems should be OFF when fueling.

 

this has happened to me as well a few times and i'm about to reach 25000 miles. i am going to have toyota take a look at this when i take it in for my regular maintenance...

 

Toyota in all their infinite wisdom has put in a weird coding policy with their fuel gauge. If you don't put more than 3 gallons of gas in the car, the gauge won't move... I had to fight with a rental car company about it... Not sure if this is your problem or not, but there is that.

 

Scangauge 2 is great .... u can see how many litres or gals u have used.... great for instant mpg, average mpg, coolant temp. 12 volt battery charge, etc.
