What happens to the fuel gauge when you turn off the ignition?
Sometimes, but not always, after you turn the ignition right off the fuel gauge moves (normally very rapidly) from zero to about 2 oclock (regardless of the quantity of fuel in the tank). At the same time the temperature gauge moves to a (more realistic) position. Is this an electrical problem, eg water in the ECU? I’d very much appreciate help.
Why do the needles on the fuel gauge go up and down?
I noticed that during the last few days, when I start the car, the needles on the fuel, speedometer and temperature gauges go all the way up and then back down. After they finish moving, I then see the engine lights go on and off. Normally, when I start the car, just the engine lights go on and off. The movement of the needles on the gauges is new.
Why does my car’s temperature gauge keep fluctuating?
The radiator could be plugged, could have plugged cooling passageways, could have a defective water pump, loose belt issue, collapsed hose, excessive load on the engine due to dragging brakes, underinflated tires, and so forth.
What to do when your car gauges are not working?
The fuse should have power on both sides when the ignition key is turned to the on position. You can check this with an inexpensive test light or multimeter, or take your car to a mechanic if you don’t have the right tools or aren’t comfortable digging into a diagnostic like this.
Why does temp gauge go to full hot when you turn car off?
The temperature gauge is reading the temperature of the coolant in the block, NOT the temperature of the block/heads/intake. They are much hotter than the coolant.

What happens to the fuel gauge when the tank is full?
As the water rises, the float arm rises until it shuts off the fill valve when full. In a fuel tank, as the fuel level rises, the fuel sending unit float rises, and a variable resistor changes the resistance in the electrical current running to the gauge so it reads full.
What happens when your gas gauge is not working?
The gas gauge tells you how much fuel is in your gas tank and alerts you when it’s time to refuel. If your gas gauge is not working, the inaccurate information it provides may cause you to run out of gas unexpectedly.
