SOURCE: 2005 Nissan Xterra gas gauge reads empty when full of gas.

Sending unit died. can be expencive to replace since most sending units are integral with the fuel pump now. lots of labor too. Better to use the trip odometer till you can afford a day without your car and a $600.00 +labor repair bill.

SOURCE: 1992 f 159 dual tanks fuel guage not working

You will need to remove the wire for the sending unit on the tank and ground it to the frame with your selector switched to the tank you are working on and the key on. If gauge comes up to full then the sending unit is bad and gauge is good. Repeat process on other tank. The fuel tank switching valve on the frame also switches the wiring signal from either tank for the gauge. If no change with first test you will want to check the valve.

Tank empty, gauge reads 1/4, tank full, gauge reads full, tank 1/4 full, gauge reads 1/2. Engine off, gauge reads below empty. Any ideas will be welcome.


The values differ in all types of cars. Older cars peg out at 90 ohms. Newer cars range between 0 and about 400 ohms. Dis-connect the connector at the sender. Ground the sender wire and the gage should read empty. un ground and it should read full. They use a ceramic resistor in the tank that usually go bad.

Gas hand floats bad and reads wrong says full when empty and empty when full makesno sense...reads different all the time though


more than likely the sending unit in the gas tank, Could be very costly/hard to replace as you must remove the gas tank to get at the sending unit.

My gas guage stays on empty and the tank is full


Sounds like your senor in the gas tank it self is bad. Most cars have a float that read out how full the tank is and when it goes out it will stay stuck showing you on the dash that your tank is empty even though it is full.

Left petrol tank stays full, not feeding/emptying - BMW X5 4.6is


inside the tank there are 2 or 3 hoses that transfers the fuel to where the fuel pump is. check for leaky hoses.

Fuel gauge wraped around to full


Fuel gauge measures resistance of potentiometer coil in tank.
If you pull wire at tank unit, and short it, it should read full.
With wire off completely, should read totally empty.
If not, gauge bad.
If ok, then tank unit bad.

You don;t say whether the fuel gauge is reading accurately, or whether it's always on empty. If the gauge is always showing empty, it's most likely a problem with the sending unit in the fuel tank. Check the resistance across the two terminals of the sending unit.

On a C900, the fuel sender level unit is separate from the fuel pump and located on the right side top of the tank, accessible by removing the trunk floor lift up panel (the pump is located on the left side top of the tank.
Possible problems are: electrical line off or broken, float not working (it's fairly delicate); or gauge not working.

Test the resistance of the sending unit with the lines disconnected, the resistance should be 2.6 to 3.8 ohms full tank, 63.3 to 67.5 ohms empty tank; and test for voltage across the top of the sender unit, if no voltage, that's likely the problem!

If the gauge is otherwise reading accurately (showing 'full' for a full tank, etc) then the problem is likely a gauge malfunction and can be simply replaced.

Good luck!
