Elantra MD (2010-15) :: Fuel Gauge Shows Half But Tank Is Full
Mar 22, 2015
I just bought my 2012 Elantra Limited from the dealer today . The fuel gauge showed about two bars, a quarter tank I estimated. However when I went to fuel it, the pump clicked off after about 1 gallon, indicating the tank was full.
That was odd so I just figured there was some air in the tank or in the hose, so I tried adding some more fuel. I got about a half gallon more added when it clicked off again. Well, I know you're not supposed to top off the tank so I tried to add more. Got about two gallons added when it clicked off. I stopped fueling at that point for fear of causing damage.
My fuel gauge now shows a little less than half full. How can that be? Is there something I can do to fix this?

Been driving for 3 days now for a total of about 100 miles from a full tank averaging 50 miles per gallon. I noticed the gauge still shows FULL. Not even a bar below or something. Is there anything wrong with my gauge?

My fuel gauge acted pretty weird today. When I left my house today it was just above half a tank. I was sitting in traffic quite a bit and then looked down and it was below the e. I knew it wasn't empty so I kept going. Got to work. Went for lunch and it said full drove about 5 mins to eat and it went down to half a tank. What's going on? I am thinking of the fuel sender or wiring?

As I was driving to work yesterday I noticed my fuel gauge going from half tank all the way to full going down the highway. I started looking at the rest and they seem to be in there normal spots. I looked up and watched the outside temp go from 40 degrees to 5. This morning the fuel gauge goes straight to full and the outside temp bounces between 2 degrees and 10. What may be going on to cause this?
The truck is a 2000 F350 crew cab with a 7.3 Power Stroke

I've been having a very erratic fuel gauge issue as of about 2 months ago. My fuel level would register full, when in fact I knew it only had 1/2 a tank or so. Then 5 minutes later it would be pegged on full. Under a 1/2 tank the gauge would read any where from 1/2 to empty from 1 minute to the next. So last week I decided to drop my tank and take a look. I was thinking maybe my fuel sender was broken, maybe a loose wire in the tank, or even that my float had dropped off in to the tank.
After dropping the tank, I removed the PK-Up and sending unit and everything was intact. I placed my ohm meter on the sending unit and it checked out fine. So I took the Pk-up and rolled back up underneath the truck and plugged it back in. I had my son turn the key on and off while I moved the float to different levels in order that it would register. It registered empty, 1/4/, 1/2, 3/4 and full just fine as I moved the float to those levels. If you leave the key in the run position and move the float, it won't register or better said, the in cab gauge will not adjust with the movement.
You have to turn the key off move the float and hold it there, then have your assistant turn the key on and the gauge will show the position that you've moved and held it at. I simply removed the plastic cover from the sending unit, and sprayed it down real good with electrical contact cleaner. I didn't scrub the copper contact area at all.
I was concerned that scrubbing might remove more than I wanted to, and really mess things up. I attached an Ohm meter and checked resistance thru out the float travel. All checked out good and I reinstalled it. So now my fuel gauge is working as it should be. I did make a video while I ohmed the Sender Unit thru it's travel, but for some reason it won't load.

I recently bought a 2005 Ford F250 Super Duty, diesel 6.0.
As I was driving to work this morning I noticed that the fuel gauge read almost full when it should have only had a half tank. A little while later I heard a beep and saw that the gauge was now on empty with a "Low Fuel" message displayed. Then I noticed the heater was suddenly blowing cold air.
I've only had the truck for a few weeks, but haven't had any other problems. I did replace the CD receiver and all of the instrument cluster lights a couple weeks ago, but everything seemed to be working fine after.

I been having this issue when I drive to 0 miles left on gauge, then fill it at gas station and it clicks like its full, but shows only 8.5-9 gallons? And fuel gauge shows 1 bar missing from full.
2011 66k miles
Took to dealer and they replaced gauge module and was ok for 2 fill ups but now its doing it again.

Ok so the fuel gauge says empty and the low fuel light stays on even though the tank is full. I'm assuming its either the gauges or the sending unit. If it is the sending unit where is it located on this car?

My gas gauge is intermittent. most of the time it reads right, but like 30% of the time it shows empty regardless of how full the tank is. What would cause this?

I have a 2004 Nissan 350Z. During the first few years of the car, I always had a gas gauge that read correctly. Then, I had a recall notice about the gas tank. I took it in and got the part fixed. Now, my gas gauge does not read correctly. It rarely shows that it is full. In fact it looks like the needle "floats" up and down when I have driven it and used some of the gas.
Another thing I noticed is if the tank reads below 1/2 a tank and I go in to fill the tank, then start the car up, it looks like the needle just "sticks" and then jumps to almost full. I have put in some gas cleaners to see if that would work and it does a little but two things I would like to know:
If I decide to get this fixed, what is it that I should call this problem? When I mention it to the mechanics, they always act like I am nuts or they have never heard of this problem.

I recently took a drive down CA to visit some friends. The whole drive down, my gas gauge did not move one notch. Finally, when I got to SB, it had moved down a couple of notches. By a couple, I mean 2 at the most. The next day, we drive to Costco and all of the sudden my C stops and says problem with the hybrid system. My car had run out of gas however my gas gauge said I still had plenty over half full. This is partly my fault since I shouldn't have expected to have gone so far on the tank, but at the same time, why isn't my gas gauge warning me like a normal car would. I have an appointment to get the gas gauge fixed this weekend. My car has 4000 miles on it now.

I have a 2001 Chevy Silverado with the 4.8L V-8 engine. It acts like it is running out of gas ( the gas tank is over half full). The truck has sat for about 6 months in this condition without being started here in Sacramento, CA. I then replaced the fuel filter and for a few minutes it started and the engine ran fine (without actually driving it). A few days later I started it again and it now again acts like it has fuel starvation, it will rev up briefly then act like it is running out of fuel. I know the fuel pumps are the Achilles Heel of these trucks, but before I try changing it I was wondering if there might perhaps be another problem such as the new fuel filter plugging up quickly or possibly an electrical problem. I've always heard these fuel pumps either work or they don't work, nothing in between. This problem is intermittent but big enough the truck is not driveable. Is there any way to get a good take on the problem before diving into the fuel pump replacement and hoping that solves the problem ?

I have a 2004 F150 XLT 5.4 L 79,000 miles. Yesterday i was driving home turned a corner and the low fuel light came on and the fuel gauge is well below empty. I had approx 1/2 tank of fuel when it happened. I have since filled tank all the way but the gauge will not move and low fuel light stays on. Everything else is working fine! I have never run the truck low enough on fuel to make the dummy light come on.....

Here is my car info:
-------------------
1994 Ford Escort LX (Wagon)
1.9L SEFI engine
Just installed a new timing belt, water pump, thermostat and serpentine belt (the car was running great)
Here is the exact sequence of events that caused the issue:
----------------------------------------------------------
I was working on the car
I backed up on to wheel ramps so that I could check the exhaust
I noticed that the car was idling high, so I removed and lubed the IAC with WD-40
I put the IAC back in place with grey RTV and tightened it down ( It's not leaking at all )
Here are the exact symptoms:
-----------------------------
I turn on the ignition switch
The fuel pump pumps and sounds normal
The Fuel gauge shows about 3/4 tank (which is accurate... I recently filled the tank)
The low fuel light comes on (which makes no sense to me)
When I turn the ignition to the start position, the car cranks and sounds normal, but it doesn't even attempt to run. When I crank the car the Low Fuel light goes off, but the Fuel Cutoff light comes on (only while cranking). I also notice a slight smell of gasoline, but I can't find any fuel leaking or dripping anywhere!
What I've tried:
----------------
Looking for fuel leaks ( can't find any). Made sure the IAC is properly connected.
Verified and tested the Inertia switch in the right rear of the car ( it is working properly and has not been tripped). When I trip it, the fuel pump does not run. When I reset it the fuel pump works properly again.
Disconnected the + battery cable for 5 minutes or more in an attempt to reset the ECU. It didn't work. Symptoms remain the same.

I was involved in a collision and had my 2005 Prius (direct from Japan import) in a collision repair shop. The shop performed the necessary electronic checks and fixed the superficial damage to the Prius. After a time, the car was completed and I drove it off-the petrol gauge was at the half tank mark.
One week later, driving 80k (~50m) a day, my gas gauge is still at the half tank mark. I decided to fill up the tank. I paid for what seemed to be almost a full tank price...and the gas gauge increased by one increment only. It still hovers at one bar over the half mark.
Scouring the web, and this site, I found a fuel calibration protocol. Here it is .....

Over the past approx 3 weeks Ive noticed that my gas gauge stops at about the mark half way between 3/4s and full now. Previously when I would fill the tank it would go about 1 click beyond full. Today,with the needle damn near on empty I filled up and it only took 9.13 gallons. During this same time span I am only avg approx 17mpg where prior i was getting over 23/24 mpg.

1999 Dodge stratus fuel gauge works form Half to Full. Fuel pump replaced and mechanic thinks the BCM is bad. Need to figuring out the issue. Fuel gauge was checked and it gives the correct voltage.

fuel gauge does what it wants? It goes down to half way then goes back to full or sometimes even empty. Not a big deal for me because I have gotten used to it. But I would hate to have my wife in here and she thinks it's good and run out.

My 01 sl2 wont start and the gauge says that the car is empty (before this problem, everything was working fine). I know that I have more than a half tank of gas, the car continuously turns over but wont start. I replaced the fuel pump and still it wont start (not to mention that the tank was more than half full at the time). I checked all the fuses and relays and everything seems fine. I am not even getting gas pumped to the filter.

Full tank and the gauge reads empty. Has happened to me a few times. Occurs after a fillup and disappears after the car is left to sit for a while off. I would hate for this to happen on a long drive. Dealer hasn't been able to duplicate the issue. Am wondering if this might be related to the hiccup in some way. Also, am wondering if this is a fuse issue.
