Whenever I switch on the car, the fuel gauge indicates that the fuel tank is full even when the fuel is very low in the tank. What causes the fuel gauge to give me wrong readings? How can I fix this problem with the fuel gauge? I will really appreciate your help. John Tety from Tanzania.

SOURCE: 2002 Avalanche gas gauge problems

Gm has a real problem with fuel tank sending units. That is what is wrong. You need a fuel tank sending unit. You can only get them aftermarket with the whole fuel pump module, but you can buy them seperate if you buy it from the dealer.

SOURCE: fuel gauge reads E when first started, jumps to F after awhile

I agree with philipk and I might consider a different shop since separating the level sender from the gauge isn't rocket science and only requires a basic meter to check the integrity of the sender. If it checks bad, it will still cost a bit of labor (the sender isn't expensive; <$50 US) but since it is located inside the gas tank and is rarely removable without dropping the whole gas tank, expect some labor costs. The cost of replacing the instrument cluster would be far greater though if the sender checks out OK.

SOURCE: 2002 Chevy Suburban: Fuel gauge reads empty, tank is half full

Youre gauge is controlled by a plunger in the fuel tank which is attached to the sensor and the fuel gauge. it sounds like when the plunger goes down half way its either getting stuck down lower then it should. Needs replacing. Any mechanic can do this install for you.

SOURCE: The fuel gauge doesn't read right, makin' low fuel light flash

if the fuel pump is all in-tank; the sending unit built in to the fuel pump is most likely malfunctioning; if so, this will require removal and replacement of the entire fuel pump, sometimes expensive, others not so much

Sorry to say,but the fuel sending unit is the problem,the fuel tank will have to be lowered out of the vehicle to replace the unit.If the fuel sending unit is not available by itself you will have to replace the whole fuel pump assembley.

Fuel gage showing half a tank but trip computer only registering 60 miles left


Its very simple. If the gauge is showing half full then fill the tank and see how much fuel it takes. If the amount you add is approximately 50 percent of the fuel tank capacity then you know the fuel gauge is accurate . In that case the computer is giving an inaccurate reading and should be ignored. All you need is an accurate fuel gauge - it does not matter a row of beans what the computer says if the fuel gauge is reading correctly.

I have a Toyota Echo 2004 , the fuel tank indicator on the instrument panel stop working even if the car is completely full the ligth is on , indicating low fuel.


There is a flotation operated sender inside the gas tank, which provides information to the gauge.
Either your sender has died or become corrupted by taking on gas, or the gauge has died. Probably easier cheaper and faster to have the gauge checked out at a dealer than to pull the tank out. Might be a common problem on that model or year. Ask a dealer service department how much to figure it out.

89 jeep Grand Wagoneer fuel gauge not reading.


Did the mechanic use an OEM replacement unit or an after-market unit? I think the original unit has a damping circuit to prevent immediate response when accelerating/stopping/cornering; the needle reacts slowly to changes in fuel level. If the new unit shows an immediate transient response, but settles back down to the actual fuel level, I'd just live with it.

1990 toyota camry gas gauge quit working


Either fuel sensor is bad or coated with sulfur residue from inferior gas. Try a can of Sea Foam gas treatment OR can of Techuron concentrate. Both available at auto parts and , of course, Walmart ! Add to full gas tank, drive 75 - 100 miles and see if all is well. If not, condide4 sensor change

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!
