I have a Yukon. I just filled it up and when I started it the gas gauge went to empty and low fuel light came on, but tank is full. Will I still be able to drive it until I can get it fixed or will it strand me??

You will be able to drive it just fine.

Fuel level sensor code came on my ford f150, had a new fuel pump and sensor installed and it still show low fuel, any suggestions


A shorted wire is possibly the problem.


Hi I just purchased a 2011 hyundai sonata and the gas gauge doesn’t tell me how much gas I have. The empty light keeps blinking..can it be the gas pump or sensor.. what can the approximate cost be for this?
Thank you


I have the same problem with mine since I purchased it back in July. I would like to know what it is and how much I’m looking at spending to get it fixed. Or is it included in the warranty that I have

2003 Saturn, L200, 2.2 L engine Service light is ON, Gas gauge shows empty but it isn’t, and Security light is ON. They didn’t come ON until I drove 20 miles down the road. What’s the problem?


Hello 2005 mustang. Had check engine light, Ford dealer read code as replace fuel pump, I did now fuel gage fluctuates from accurate to empty. When empty read the idle drops. Thanks

2004 ford explorer fuel Guage malfunctions does this mean that the fuel pump is going


No, the fuel level sensor is attached to the fuel pump assembly, but does not effect the pump at all.

I have an 08 Tahoe. We had our sensor changed (twice) and it is still not calculating the gas right. It will go from full to 1/2 in only a few miles or stay on full for a while then go right to half. My airbag light is on I was wondering if it may have something to do with the computer?


2000 Ford Explorer makes noise every now and then when I hit gas noise stops. Had fuel sender replaced one year ago. Is this going again?


I have a 2013 Chevy cruze, I filled my tank up and it’s still stuck on empty and I’m not sure why is going on. This has happened before but the gauge started moving after I drive for a while. Could you tell me what is going on?


I wanted to purchase a 2003 Chevy Impala but the check engine light is on I had it checked they said it’s the fuel level sensor my question after reading the forum is does that 52nd the Chevy would have a code since the check engine light came on or is that a easy fix!

I recently was rear ended by another driver while stopped at a red light. Since the accident, my fuel gauge stopped working properly. It sometimes reads empty when full and full when not totally full. What’s up with that?


My car keeps shutting off it don’t run hot.. The gas hand moves up and down when gas in the tank. How can ibfix this problem?


I took my 2009 Silverado to where i bought it for transmission fluid change. While in the shop my fuel guage stopped reading. It’s always on empty but tank is full


I have a 2002 ford explorer v6 and everytime I full the car completely in till the gas handel clicks and cant take no more. Then I start the car and the gauge only goes 3/4 of the sT up but I know it’s full because the handel clicked to max. What could it be?


I have a 72 Chevy pick up. I changed the complete float and sending unit.
I also sent the tank out and got it cleaned.
My problem is my gas gauge indicates more than full like twice as much.
When I disconnect the wire to the gauge it indicate full.
I have my tank full of gas.
What is causing this strange reading?


Why would my gas gauge go from full to 3 quarters of a tank over night just by sitting in my drive way. Fill up over the weekend did not drive tell monday 3 trips to same place then back home it was hott out the day i filled up and was hot out monday and when i got hone monday eveing about 350 gas guage showed full it was cool this moreing and noticed the drop in gas what coukd be going on?


Fuel light is on but gas is spilling out. Put 10 dollars and it didn’t spill. Second time put 5 and it all spilled. Any ideas??


Is it possible I pour wrong gas?


What about if you had a half tank and the next day showed a full tank?


Had my fuel pump changed now the fuel gauge is reading incorrect how do i fix it


Either the mechanic did something wrong during the replacement, or the fuel sensor got damaged or is the wrong one.


We have replaced the pump ,fuel sensor and the?? in the dash. we drove from Nebraska to Texas and back and still every time we fill the tank it will go to empty for a short time and repeat it over. The funny thing is if you honk the horn a couple times it will go back to full only to repeat again until you get down to 3/4 of a tank.


What will it cost to replace the fuel sensor on my 2000 Pontiac Grand AM?


What is involved for replacing fuel sensor on 1989 Buick century ?
& how much 🤑


The fuel tank needs to come out of the car, then the fuel sender assembly gets removed from the tank. As long as there is not a lot or rust, the labor for this job is about 3 hours.

I need a estimate of how much its going to cost to have my fuel pressure senor replaced on 06 impala.


Estimate cost of fuel pressure regulator replacement is the part= $90, labor- 1 hour.


I replaced my alternator , the car cut off and the gas level went to empty. When the alternator was replaced the gas level still says empty. I was told without looking at car to buy a fuel tank assembly but I don’t think I need that.

We changed the fuel sending unit on the 2003 pontiac montana and about a week later when j start the car the gauge reads empty and when I start to drive the gauge starts to work normal…..question why!!!! It it another sensor or a easy fixes please help


I replaced gas tank and the whole gas pump assembly unit on my 95 tahoe and my sending unit doesn’t work…..please help me


If this problem started only after replacement of these parts, then you could have the wrong sensor, a broken wire or a bad sensor.


1979 chevy c 20 3/4 ton pickup .. topped off both tanks & the fuel gauge is now reading 1/2 full when i switch to either tank. simultaneous sender failure in both tanks or indicator problem in dash ?

Edwin Arellano

Hey I have a 2003 chevy silverado and the fuel gauge doesn’t say if it’s full or low it’s just sitting down and everytime I fill it up with gas it doesn’t say full


You need the fuel level sensor in the gas tank.

Scott conner

I have a 2003 Ford Mustang GT and the level on the fuel gauge says low and the gauge reads empty when in fact the car has fuel

Willie fontaine

I’ve got a 1999 Pontiac sunfire as my gas gets run down my gas gauge goes down but it stops at half a tank then starts to go back to full as I run more and more gas out what would cause this the same fingers ?


Yes, the fuel level sensor is bad on your car. The resistor can burn up anywhere on the sensor or the fingers are corroded.

This has fixed 4 different cars in the past for me. Go to your local auto parts store. Purchase a bottle of either Redline SI-1, Techron COMPLETE fuel system cleaner (NOT INJECTOR CLEANER, MUST BE COMPLETE SYSTEM) or bottle of Gumout REGANE. The ingredient you are looking for is PEA. PEA is what cleans the system. If it doesn’t have PEA , which most do not, IT WON’T do anything. The 3 products I mentioned contain PEA, are proven to work and readily available at local auto part stores, walmart, etc. The exception is Redline SI-1, the only local place that sometimes carries it is Orielly’s, the other stores do not. Amazon has it too. Here’s my method that worked on 4 different vehicles. Cars and trucks. I buy 2 bottles of said treatment. I allow vehicle to get down on fuel as low as I can. I pull up to gas pump, I dump entire bottle into tank (doesn’t matter if its 12 gallon capacity, 26 gallon capacity or 40+ gallon capacity). I then put 4 gallons of PREMIUM fuel in tank. Drive around until near empty then repeat process with second bottle. On third fill up, I fill it full with Premium fuel and problem is resolved. If you’re lucky enough to live in an area with Chevron gas stations, THIS is the fuel to use. Chevron adds the same additive in their fuel as what comes in the bottle. I’d be willing to bet that anyone who uses Chevron exclusively doesn’t have fuel gauge problems or at least much more rare. Since Chevron is not available to me, I use BP or Shell. If this fixes the problem, put a bottle in the tank every couple months to keep it clean. Another good thing to do is… Read more »

Brian, I followed your instructions on a 2002 Pontiac Grand Am and IT WORKED!! so far anyway. I did this a few days after the gage was stuck on empty. I bought Gumout with PEA at Walmart. After the second fill up and second bottle of Gumout the gage returned to a full tank register! THANK YOU SO MUCH FOR THE TIP!!


Thank you very much, your information help me to find out where the problem is!!!!!


I have a 2002 blazer with a stuck gas gauge.could it be a bad ground?

Linda Townson

Where is the fuel sensor level gauge located on 2007 Chet Malibu. Gas gauge woks when it wants just not often

The fuel level sensor in your Chevy Malibu is located inside the fuel tank on the fuel pump.


Thank you so much for the clear explanation of how the gas gauge works. My gauge suddenly stuck on the near empty mark on my 1993 Nissan Sentra when I filled it and I was told I needed a new fuel pump!


I have a 1999 Buick lesabre I have had bout 6 months. Have never filled it up until yesterday and today hen I did…the gas gauge moved back to the empty mark. Does Anyone know why?


I am told from research it may be a faulty slosh sensor on 1992 plymouth voyager

Rebecca Dailey

My daughter has a 2015 Chevy Cruze.
This was a wreck that we fixed back for her.
The gas gage has not worked accurate for a couple months. Now it’s showing empty all the time. Has no lights or codes. The gage is just staying around the E.
What could cause this?


I have a 2006 Chevy Uplander. I just put almost a full tank of gas the hand went to empty and said low fuel. Can I continue to drive it till Saturday will it be OK or should I take it to my mechanic asap please respond thank you very much


Did you ever get your problem resolved if so how ?


My 2006 Chevy Cobalt LT says that there is NO FUEL but when I went to fill it up, the pump quit at 3 gallons because it was FULL. Not sure what way to go about this without paying an arm and a leg.


Where can I get this fuel gauge fix for a Cadillac 2002 SUV, in North County, Missouri 63033


Hey man I have a 1998 isuzu rodeo 2.2l 4clyinder and my gas gauge stays on empty all the time we have change the cluster 5 times and the sending unit(which has the fuel pump all in 1) about 2 times me and my dad can’t figure out why it does

Mechanic Joe

If the problem is not in the sending unit in the gas tank, or the dash, then you have a wiring problem somewhere between the two.


I have a 2002 Nissan Altima,I never had this problem but when I started my car my gas light was on and says empty but I had just fill my car up an hour ago. Could you please tell me what is it that cause it.


My fuel guage on my 05 2500 dodge ram stays at a quarter tank and wont go down. But when i put gas it goes up! Anyone know why?

Check your mass air flow sensor

What in the heck is wrong with that now?

I recently purchased a 2003 chevy blazer and the gas gauge is constantly going from empty to full as I am driving. We went on a camping trip this weekend and the service engine soon light came on so I went to auto zone and had them check it and it come up with the code p0442. Can someone tell me what the problem could be since it has the code and the fuel gauge problem?


hi ! I have a 1981 delorean the gas gauge on my dash board don’t work it shows that is allways on empty I need help thanks


i have a 04 malibu. the check engine light says po442. i took it to a repair shop they pumped smoke through system and told me i have a bad vent valve. also the gas gage is flipping from full to empty all the time. is this two problems or can this be fixed by one part being replaced and which one or ones is it? i would rather do this myself if possible. the repair shop already charged an arm and a leg and gave me very little info.


Hi I have a 2001 acura MDX the gas light is on and my tank is full and the gas gauge do not move can you tell me what mite the problem be and if you know how much it would cost to be repaired because I know the dealership is going to over charge me

I have a 94 crown Victoria and I have a Digital meter it is always reading less then what I put in NY tank what can that be…


What is the code for the fuel level sensor on an 2002 YukonXL

Karl Bagley

I have 83 F150 put in a new fuel sender and when I fill it up it reads full then after 1 hour it reads half then a little while later it reads empty


It is either the wrong sensor or you have a poor electrical connector.


i took my traverse to the dealer cause gas gauge was acting erratic, the technician said the interior dividers of the tank are broken creating that issue.
is that correct?


Yes, I have seen this several times. The baffles inside the tank get loose and stop the float of the sensor from moving properly.


I have a 2006 dodge dakota with a 4.7. It has a slight hesitation on acceleration

Tom McCall

my 2008 chevy silverado 3500HD diesel fuel gauge started showing empty when it was 1/2 full the low fuel light is on and the DIC says low fuel ? is the problem the gauge or the fuel level sensor, How could I check out the right problem and the fix


I have a 1988 ford f150 and the truck will be out of gas and the gauge will say empty then I can put in like 5 gallons and it will go to full

john y

I have a 1998 ford f-150 pickup 4.6 liter engine that even with 3/4 tank of gas I will get a low fuel lite and engine wont start. I will wait 20 minuets or so and move the truck by hand 6 feet or(I guess slosh the gas) and it will start. happened recently after finally starting drove 45 miles home without putting any more gas in it. ???? do not have a clue.


I have a 07 chevy cobalt my gas gauge has been jumping from full to empty on its own and the steering wheel locks for this has been going on for awhile I took the car to a dealership they claim they fixed the problem and they had to replace the serpentine belt spent $450. Now a few weeks later still the same problem. I take it to a service center he tells me its a computer issue spend $300 a couple weeks later samething. Now he’s telling me its the transmission control module. I am so confused I don’t know who to trust Please help


I have a 2013 Chevy Suburban 3/4 ton, and ever since I purchased it and I take it on a long trip (800 plus miles in a day) at some point during the drive the fuel gauge will fall to empty. It has happened on every long trip. It eventually comes back, sometimes it might take two days. I have had it back to the dealer and they say that they can’t find the problem. Of course every time I bring it in the gauge is reading properly. Any suggestions would be appreciated.

I just changed the full pump and the needle gauge dont work and the light for gas it’s on.


i have a 1997 ford Taurus my gas gauge read empty too but i was wondering could it be some thing else too or is that the problem


I have replaced the fuel pump in my 2006 F150 twice having the same problem because when I put gas in my truck the gas gauge reads empty and my fuel light comes on but my tank is full. It stays this way until I crank or drive my truck about six or seven times and then the gauge will go to full and work regularly. Why does this keep happening???


My gas gas since I got it says empty even after I put gas in it and when I turn the car off it always say over a quarter of a tank on my 1997 Chevy 4×4 blazer


my fuel pump was replaced now my gas hand want read any idea about the problem

I bought a new Toyota Corolla LE Plus (2015) and the
cruising range and gas gauge needle are way off. A quick
descent from Full to 1/2 Full,
and then it seems to level
off a bit. The only reliable indicator is the odometer
which is also a bit screwy at times. The dealership claims that the new ones are all like that, and that it is
a computer programming design error which cannot be altered. I want a new vehicle!! (swap it out). Has anyone
else run up against this problem IN A NEW TOYOTA? What are
my options? Lemon Law saus it’s hard to prove gas mileage.


Are there any type of sensor that would be located on or above the gas tank on a 2003 gmc yukon that would cause a check engine light to come on and would require the tank to be removed to get to the sensor. I was told my map sensor was bad and the gas tank had to be lowered. Pretty sure the map sensor is on the engine. Did the mechanic just say the wrong sensor is he trying to rip me off.


I have a Ford Fiesta 2005 model and my gauge read empty but the tank is full i have replace the fuel pump and replace the cluster but still shows empty can it be that there might be something other than that can be faulty what can i check next,this is so frustrating please help


i have a saturn vue 2003 the gas gage is on e i fill it up and its still says E. i took it to get fixed he said both of the fuel pumps are fine and the sensors on it are good. could this be the fuel level sensor that makes the needle move that need to be replaced .


I have a 2001 Lincoln Town Car. Everything was working fine until I filled it with gas today and the guage stayed right where it was before I put 13 gallons in it. Would a fuse go out to cause this problem?


I have a 2005 Pontiac sunfire fuel gauge is all over the dash any clues whats causing this ?


I drive a 78 Jaguar XJ6, I accidentally left one of my fuel caps open after leaving the pump and drove on the highway at 100kms for about 15clicks before realizing and pulling over. After this happened the fuel gauge stopped working and sits at “E.” Its never done this before and the car is well maintained. The jag has two gas tanks which can be switched using a button on the instrument panel, even when the tanks are switched the gauge still reads Empty even when full. Got any ideas?


because it wasn’t running no noise when I turned key on checked all my fuses and there good


i have a 2002 Saturn sl100 series and my security light is on and my fuel guage reads empty but before this problem started I got gas and on the way home my battery died and I got a jump start when I reached my house the car was puttering like it wanted to cut off I figured it was due to the battery dying so I shut it off myself ever since haven’t been able to start it back up it turns over just wont start. replaced the fuel pump because it was running but when I tested the old one it also still worked. I did the relearn for my security and my light went off but sill nothing on the gas guage.


Replaced fuel sending assembly on 04 Bonneville and gas gauge reads full until tank is 3/4 empty then gas gauge starts to move.


If this is the same problem as before replacement, you have a corroded wire to the sender. If this is a new problem, you got the wrong or a faulty sender.


I realize this is an older article, but I have an older vehicle. A 97 gmc safari van to be exact. The gas guage reads empty when the van is on, and sometimes above empty (a little less than 1/4) when it’s turned off. As you noted the common problem with the sender it was my first guess that the fuel sending unit was bad as well. 3 hours of labor later, and around $300 bucks for the new pump/sending unit, I find the same problem still exists. Not really sure where to go from here. Instrument Panel? I read a post where the motors on the IPC can go bad. I’ve also heard talk about ground wires. I dont know where to go though.

did you ever resolve this problem? i am having the same problem with my 1998 gmc k1500

I would check the wiring before replacing the instrument panel.


I have a 2003 grand prix. when it is in park the fuel gauge reads full and when yo put it in gear it will read empty and the fuel light will come on. Any ideas on what would cause this?


Most common problem is the fuel level sensor in the gas tank.


I did take your advice and ended up replacing the fuel sensor and now the fuel gauge works great………….Thanks for the help


If my fuel level sensor is bad, but my tank is full, would my vehicle think it is out of gas and stall?

Answer: No. But if the sensor is bad, and your are out of gas it will.
