I have a 2009 Sonata SE 3.3 with about 35,000miles. I am the second owner.
I believe that my gas gauge or the sending unit in the tank is bad. The gauge will show empty when the tank has fuel and then it will sometimes read normal.
I just filled up my gas tank and when I turned on my car the gas light turned on and the needle read empty. But before I put gas, the gas light wasn't on yet and. Was at 1/4 of a tank. Maybe I filled it up too much and it'll resolve itself after the gas goes down?
It's a 10.5 if it matters.
I bought a 2006 F250 6.0L a couple of months ago, from a dealership. It's been bulletproofed already, has an intake, coolant filter kit. Has 95k (mileage). Today, my fuel gauge dropped to empty from 3/4 of a tank for a couple of miles and set off the CE light. I hooked my scan tool to it, to clear the code (P0460).
After just checking other things out with the scan tool. I cleared it and went on... I had to run to the store, later on... I was pulling out of the neighborhood and the gas pedal was a lot more "touchy" and the truck, responded to it and it launched pretty good and blew a good amount of black smoke.
Do any of you think this has/or had a tuner on it and I may have activated it with my scanner?
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.....
View 5 RepliesI have a 2004 Hyundai accent hatchback with 225000km. The first time I drove it for over an hour, 1 trip no stops, the fuel gauge dropped to empty while there was 3/4 of a tank. The 2nd time I drove over an 1 the fuel gauge dropped again and the gas light came on (again around 3/4 of a tank). My mechanic said until it does it consistently he can't diagnose so I let it go.
More recently, driving it to and from work 5 days, plus some extra city driving, I used 1/4 tank the full week. Today I picked up 4 winter tires and bringing them home (approximately the same distance as my work) I used 1/4 tank right there. I understand it is weighed down, but could it really be that much? What is causing the fuel jumps and gauge jumps? I've already had the float replaced.
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.
View 8 RepliesIts been happening often where it shows empty (when i really have half a tank) and my avg mpg resets itself. As I am driving it will go back to normal.
View 11 RepliesMy 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.

All has been well in just over a month of driving the car and about 3300 miles logged. The 12v, Aux battery was dead from the car sitting on the lot for so long (I replaced with a new OEM Toyota 12v battery) After a week of the car experiencing dim headlights, and various other electronics
No codes or CEL though.
Now that the 12v battery has been replaced, the car runs exceptionally well, aside from an intermittent fuel gauge issue where it only reads full bars (completely full) if I let the tank get to empty (Flashing single bar) or close to that. If I fill the tank from s
So yesterday I was driving home from work.. I know my tank was 3/4 full. All of a sudden, my low fuel light came on and my gas gauge needle went to empty.
The needle sits at E, but it still says about 20 miles till empty on the MFD. When I left the house this morning, it said 5miles till empty.. by the time I got to work, it said 20. Kinda odd..
I will hook up the vagcom when I get home tonight, any area I should scan for? or just a complete scan? There is no CEL error on the dash though. What I could look at to fix this?
I recently replaced my gas tank in my Sundance, it was getting very rusty around the sending unit area and was starting to leak. Everything is back together and it is running well with no leaks. The new problem that it has, when the car is running, the gas gauge shows less than empty, even though it has a considerable amount of gas in it. When I shut the car off, the gas gauge slowly moves up to where it normally would be when it would be running. Did I somehow mess up the ground or did I cross something? This is my daily beater car and need a working gauge.
View 1 RepliesOk 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?
View 4 RepliesThe installation of the new 50 gal. Titan tank went well overall. Start up was smooth with no leaks but the fuel gauge is showing empty with about 45 gallons in the tank.
The sending unit was properly oriented ("clocked") so I'm guessing the electrical connector is not secure at the top of the sending unit. Not sure I can reach the connector without lowering the tank somewhat.
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?
View 3 RepliesI just bought a used 2004 F-350, 4x4, crew cab, short bed, 6.0L diesel. I'm having a WTF moment on fuel. Gage indicates just under 1/4 of a tank of diesel but the on-board computer is flashing like crazy stating 5 miles to empty, what the hell is that all about?
View 1 RepliesI had a 2006 Corolla S 1.8L automatic with 232,000+ miles that was taken away too early by two other cars making a sandwich out of it. It was still getting 32 -37 mpg consistently and about 370 - 390 miles per tank at least before I'd look for gas. I just replaced it with a '13 Corolla S 1.8L automatic and average out near 28 - 32 mpg (but it's winter). My issue is the readout on the gauges. I've got a 120 mile round trip for work daily (all highway). On the way home yesterday, gauge showed 1/4 tank and distance said 85 miles (enough to get home).
At about 26 miles left, yellow light came on. At gas station 19 miles left til empty (or so I thought), yellow light shut off and gas gauge went back up slightly off E. Filled her up and it only took 10.2 gallons after topping it off a couple times after the pump shut off. Distance traveled was about 320 miles on that tank so around 32 mpg. I'm o.k. with that but I thought these had the 13 gallon tank like my '06? Were there still 3 gallons in there and the sending unit may be bad or am I missing something? BTW car only has about 6600 miles on it as of right now.
My 2006 Prius has 165,000 miles. I haven't had any major issues but twice in the last 2 weeks, I've had my fuel gauge go from low (2-3 bars), to one bar, to having the "add fuel" message in less than a half hour. The second time I actually did run out of gas so it's not just that the gauge is faulty. When I ran out of gas, my battery also appeared on it's last bar. After putting gas in it, the car ran fine and the battery perked up. The only recent maintenance was break pad and disk replacements but I've not noticed any drag or difficulty braking.
View 8 RepliesI changed the seal on the tank filler neck, now I run out of gas at 1/4 tank. How to "reset" the gauge?

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?
View 6 RepliesI had a fuel sender failure a couple of weeks ago. 60k mi.
Basically: freeway driving, fuel gauge read 1/8 tank remaining, computer indicated "10 miles till empty" but the car ran out of gas. Fuel sender, in the fuel tank turned out to be the malfunction.
Towed to the dealer...they had never, ever seen this before.
I get the car back next week, just want to bookmark this thread in case any members (God forbid) have this problem now or in the future.
I still have faith in my Lexus, but want to share as this failure was very unusual.
The computer apparently calculates the fuel economy per trip (or a series of trips if the car is stopped less than 2 hours) but I don't know how to get it to display the fuel economy for the tank full. Normally I'd reset the computer upon refilling but since it calculates per trip it doesn't calculate per tank. Fortunately the fuel gauge seems to be pretty accurate and each mark is approx 1 gal so I can do a quick approximation but I'm used to having the car do the tankful calculation. BTW, I reset on MFA 1, I've never reset on MFA 2 and that doesn't show tankful economy either.
