Toyota fuel gauges from that time were actually meant to work like that! It's not drawing power from your battery with the ignition off, the needle just stays at the last reading.

I have a 1992 Mercury Grand Marquis Ls with a fuel gauge that does not work (gauge may be reversed)??? help please.


The fuel level indicating system is a magnetic type system, which consists of the sending unit located in the fuel tank, an anti-slosh module located on the back of the instrument cluster, and a fuel gauge located in the instrument cluster. The sending unit changes resistance according to the level of fuel in the fuel tank, which varies the current flow through the gauge.The pointer position varies proportionately to the current flow. In this system, the sending unit resistance is low (22 ohms) when the fuel level is low and high( 145 ohms) when the fuel level is high. The pointer of the magnetic gauge remains in position when the ignition is turned to the Off position. On some models, an anti-slosh module is used to dampen out fluctuating fuel signals from the sender. Some vehicles are equipped with a low fuel warning indicator. The anti-slosh module will also actuate the low fuel indicator when the fuel level in the tank reaches 1/16 to 1/8 full.


Do your other gauges/warning indicators work properly with the ignition on? If not, check for power at the fuse panel/fuses.

If they do then partially remove your cluster with connector still installed and check for voltage at cluster connector and gauge. Check continuity of cluster and gauge for ground.

Sometimes the anti-slosh module (if installed) goes bad in the Grand Marquis but not likely.

Sender troubleshooting:
  1. Perform test with resistors as follows:
    1. Disconnect wiring connector at sender unit, then connect resistor between gauge lead and a suitable ground.
    2. Turn ignition switch to On position.
    3. With 145 ohm resistor, the gauge pointer should contact the Full mark.
    4. With 22 ohm resistor, the gauge pointer should contact the Empty mark.
  1. Perform test with fuel sender of known quality as follows:
    1. Turn ignition to Off position.
    2. Disconnect wiring connector from sender and connect it to test sender.
    3. Move float rod away from fuel filter against Full stop position. Wait approximately 30 seconds, then turn ignition switch to On position. The gauge should read on or above the Full mark.
    4. Move float rod toward fuel filter against Empty stop position. Turn ignition switch to Off position. Wait approximately 30 seconds, then turn ignition switch to On position. The gauge should read on or below the Empty mark. If gauge works properly replace sender, which involves dropping fuel tank.

Dash gas gauge stops showing proper gas level once it hits half a tank. Then gauge will fluctuate between empty (light will come on), full and anywhere in between but seems fine from full tank to half


If the trouble with the gauge started after you worked on it then you likely damaged or created a restriction to the movement of the sending unit. You will have to remove the tank and double-check your work.

Oil level gauge and sensor


Should be relatively easy to access the wiring harness if you have even a little bit of skill. i'm assuming if you plan on checking wires you are not stupid and are capable. the fuel pump sending unit could be bad which is only remedied by replacing the entire pump assembly. it very well could be the wire(s)from the pump itself leading up to the gauge. if you know the gauge is working then either one other those two things are a possibility. the pump doesnt have to be replaced if the sending unit is bad you just will not know what fuel level your at.
AS far as the oil pressure switch goes if it was wired that way already and it previously worked properly that way i would look at shorts being a possibility. otherwise your oil pump could be out .
good luck

Why does the fuel gague in my 1988 Honda accord always read full?


check to see if your fuel gauge is working by disconnecting the fuse from the panel, if gauge reads e then ground the fuel gauge if it reads full then the fuel gauge reads fine the its the float sensor in the fuel tank. good luck have fun

My 1988 Buick Regal Limited is having an issue with the fuel gauge; it doesn't seem to be working. How could we go about repairing this?


It sounds like the fuel gauge sender unit in the fuel tank has worn our and gone open circuit and needs replacing.

Fuel gauge


What you probably have...is a worn out fuel gauge sending unit. It is not worth the trouble to fix this unless you can do it yourself, or have someone fix it for free ( a brother or relative) If it works at 1/4 of a tank, then that is all you really need so that you don't run out of gas. The sender is a coil of fine wire wrapped around a small fiber or plastic wafer. Then there is an electric contact that slides along this coil and the resistance changes in proportion to level of fuel in the tank. This allows a variable signal to be sent to your fuel gauge in the dash, that corresponds to the level of fuel in the tank. The contact, and the coil are both metal, which wear out after time. Sorry.

1989 Saab 900 low level fuel light


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!
