It is the sending unit, usually the veryable resister and arm. Remove and replace sending unit. It is , unfortunately, located inside of the fuel tank. To confirm gage operation reverse wiring to the guage and it will reverse the guage, confirming tha the gauge.is ok.
You should check to see how many "bars" of fuel you have left. A common issue with these is that the fuel sending unit goes bad, and will show you 1, 2, or 3 bars while the car has no gas. You may have run out of fuel. Even if you put new fuel in, some Prius models need to be reset by a Toyota dealer in order to make it driveable again. In some Prius models, the whole fuel tank would need replaced as the sending unit and tank is all one whole assembly. Some allow you to just purchase a new sending unit. You do also have a chance just paying a dealer for the diagnostic and having them reset the system for you. You will just have to remember to not let your "bars" get down to 2 or 3 bars. Hope this helps.
Are you sure its not the fuel sending unit and not the fuel gauge itself.Because the sending unit controls the fuel gauge level and if the float gets stuck then the fuel gauge will not work.
The solution to your problem most likely is the fuel gauge sending unit which is located on the fuel pump in the tank. SOMETIMES, the fuel pump and gauge are sold separately, but chances are, you may have to replace the whole assembly. Which is actually good measure, considering that you'll have the tank removed, anyway.
OK, your fuel indicator is wired to a sending unit that is located inside the fuel tank. this assembly is part of the fuel pump assembly. the fuel indicator sending unit is housed in the same assembly as the fuel pump.
The fuel indicator will not function properly if there is a bad ground or, if there is a fault within the sending unit. there is a floater device attached on this assembly and, it raises with the fuel level and lowers when the fuel level is low, sending resistance signals to the indicator gauge on your dash board. these signals can be disrupted if the ground is corroded or, if the sending unit is damaged.
In most cases, replacing the sending unit will fix this issue. if the fuel indicator is stuck on the full mark, check the ground. if the fuel gauge is laying on empty all the time, replace the sending unit.
