- How to test and replace a fuel level sensor. Because it's an in-tank fuel pump, the hardest job is removing the fuel pump from the vehicle. Doing this test can help you pinpoint why the fuel gauge is not working. If this sensor is indeed working on your vehicle, then check the fuel gauge itself. This specific vehicle is a 2010 Subaru Impreza.

This is a great and detailed video. You explain literally EVERY question I might have with regard to performing this test. That is a quality most youtube video's don't have. You even addressed which terminals to connect the positive and negative probes to and how to find out which lead is positive and netagive. Most videos would just say" connect the probes to the leads and then look at your multimeter and there ya go. I LOVE the detail in how you address everything here.
Yes the quetion so true..
I have this very issue with the fuel sensor on my 2010 Nissan rogue not reading correctly. I will likely be doing this soon. Absolutely well detailed video, and easy to understand. :) great find.
Very thorough explanation and detailed video, thank you! Subscribed!
Is the fuel level sensor also called sender unit?
One of the first things I learned at trade school was take off your watch and especially when you work with electricity and fuel. You disconnected the battery cable but there still can be static electricity.
give me a call 8324077765
It will only take ONCE of getting that SHOCK for anyone to remember about wearing metal jewelry/watches while doing car repairs. My Uncle was working on an 18-wheeler engine wearing his watch. He made contact with the battery and it gave him a shock that traveled down his spinal cord stimulator and damaged his spine further. He was in ICU then Rehab. Now he is disabled at 55. Don't wear metal working on vehicles.

Very well presented for someone with minimal experience like me. Very professional thank You.
Thanks so much for this video! Very helpful.
Glad to help.
Extremely helpful with my Mazda. I had to purchase a fuel pump without a float. This video perfectly explained how to change mine out and why!
Well done.
Question: on a 2005 Nissan Pathfinder...due to age & location of parts, if Im having fuel sensor issues should I just go ahead and replace the fuel pump & that gasket while the gas tank is opened? EXCELLENT video...Im a totally visual learner.
Thank you man, very useful video.
Great informative video. Can I find sensor only ... are these available. Thanx
Very detailed explanation. Thx!
Awesome. Glad to help.
Hello , very nice video !!! Thks a lot !!! If on empty indicate 53 , and full 23,6 means i have to replace it ? Is it broken ? Legacy 2008 2.5 liter
Good video. I need this repair on my Mercedes Benz E320 Diesel but I don't know which one is bad, if the right or left. Any tip?
good job , thanks a lot
Very good video. My 2008 E320 Bluetec fuel gauge need the same work to be done.
Glad it helped
Thanks so much for this video! Very helpful
Glad it was helpful!
In Uganda i need two please
Thanks for the alligator clip tip, I will start using mine, I always probe the lazy way
Is this the reason why my gas gauge is slow to reach to its gas level? Did not do this before, DO you know what I need to replace? thank you and I liked your video..
Nice explanation, in my ford fiesta gauge works, but fuel light doesn't turn on when low fuel. Ford resetted parameters and it works that day, going on and off 3 times, after refilling never turned on again. Any ideas what's going on? Thank you!
good work - thanks for sharing ,nice vid
Thank you. You are the best ❤️❤️
Thanks so much! you said that fuel assembly was from a subaru. Was it from a brz? looks like the 86s are having these problems. looks like I have to replace the fuel level sensor.
This was a 2010 Impreza non-turbo.
It wasn't clear whether you replaced or fixed the sensor. If replaced, is that part available for sale? Or does it have to be purchased with the fuel pump?
What’s a good estimation for having the fuel pump float sensor replaced? Labor wise
Thanks bro, very nice and clear...
Glad to help.
This video is so helpful
Good video
What year Sorrento is this video meant for cuz there is so many different looking ones I have seen and this one looks very close to what I need
Great video it helps me alot thanks
Glad to help!

Does this process apply along with the fuel pump of a 2003 Chrysler voyager LX because my issue is that the gas fuel needle
doesn’t mark the gasoline level correctly so it could be the fuel level sensor
so replacing this is easy as shown in this video correct?
I've been noticing my fuel gauge is erratic bounces up and down. I can't seem to find a reason able price for a new sending unit , (just presuming that that's the problem, it may just be a bad ground but just in case it is the sending unit) However I see the price if a whole fuel pump assembly that seems well made and a little more than half price . Is there any downfall with just replacing the whole pump or should I just get the sending unit and keep with the original pump ? In other words it just seems more practical to replace the whole pump with everything included . I'm not a big fan of after market part s but I'm wondering if it's worth it in your opinion.thanks
Love this video!
The reason for these bucket type fuel pumps is "Misfire Monitor." It was so strict, that it was relaxed in 1997. The modular reservoir assembly is to cool the pump, lubricate it and not suck air when low during corners. Many with larger tanks, engineers used some small amount of pressured fuel, "Tee" into the line and run a line to a brass Venturi at the bottom above the filter to create a negative space to draw fuel into the bucket. This covered the fuel pump and kept air out. Air creates a low volume problem that results in low pressure and misfire. The sensor at the bottom is a NTC thermistor. This produces lower resistance when no fuel to cover it, then turns on the light. Before ordering a fuel sender, find the "Fuel Pump" terminal in the relay-fuse center. Using the correct terminals, hook a jumper wire, amp clamp and view the electrical pattern with a lab scope. It should be even and consistent with proper fuel pressure. If not, replace the entire unit. GM designs these to last 5,000hrs. This is about 150k miles. The inside of the bucket will capture dirt and dust and is not hard to open with 3 plastic tabs and a pocket flat blade screwdriver. The tank needs emptied at this point and washed with steaming hot water. Dry with cloth & paper towels then air dry overnight. Use dielectric grease on terminals inside connectors.
My watch, ring and wallet went into my tool box after I opened it every AM. This is the reason to touch the fuel pump at the station when getting out.

Great video. Does the fuel pump level sensor also operate the low fuel level warning light?
Instablaster
Usually yes.
Depending on the manufacturer (American vs foreign), the ohms reading will sometimes go up, sometimes go down, as the float goes from empty to full. Don't know anything about foreign thinking, but domestic sending units usually have readings of 0-30, 0-90, or 240-10 (I'm guessing on the ten) when going from empty to full (or is it full to empty). Anyway, GM and Ford have opposite ideas about fuel gauge readings. One has the fuel gauge go past full when the circuit is open, the other has the gauge go past empty when the circuit is open, so don't use these ohm readings for all sending units. Check with the manufacturer to see what the ohms reading should be for your particular sending unit.
Thanks very much I really appreciate it thanks 🙏
Glad to help out. Cheers.
thankyou verymach you are number 1 of the world
Looks like I need to borrow a multimeter; my fuel level on the dash and when filling up have been inaccurate lately. Overfilled the tank to spilling out the fill port the other day because the car didn't stop it like it should have. I have a filter, strainer, pump, pressure regulator coming so my costs are already getting up there, so will test before buying a fuel level indicator. Now that I've seen I won't have to open up the fuel pump assembly to do the level indicator I feel fine with waiting since it is just clipped onto the side.
In some cases, the connector may be bas as well. I use the multimeter directly to the fuel level sensor wires and the ohms read correctly, but when I connected it to the connector and attached the ohms reader to the metal parts it gave me nothing to return so I'm thinking I'm just going to buy a new fuel pump instead of going through all the crap
I had an intermittent fuel level reading on my 2010 350Z. On my car, the wiper was making intermittent contact because the "Teeth" on the semi-circle that varies resistance from high to low (empty-to-full) were lacquered up and partially conducting, (like the volume wiper on old your shop radio that pops and snorts when changing the audio level) The wiper arm had a small copper contact point the rubs against the "teeth" as the arm raises and falls with the level. I basically cleaned the "teeth" on the semi-circle contacts (variable resistor) with gasoline and a Q-tip and the problem was solved. My sensor (wiper arm) had a cover on it that applied pressure and contact to the teeth and the only tricky bit was reattaching the cover in mid-range (half-full) to allow the cover clips to seat....lucked out and only pulled the pump out enough from the tank to allow access to the cover and the teeth embedded in plastic....don't drop the cover in the tank when re-seating!! So no cash out for a new pump or sensor!!
How do you like your Z?
@@CarsNToys well its the first car for my son so we (he) have had a few 'traction events', we put a used Japanese crate engine in, loud muffler ( boyz nd noiz), so starting to show her age a bit.....fun to drive (manual 6spd).....it would be nice if every spring cars would shed their skin and grow another brand new layer....love my Model 3, there I get new bangles every few weeks!!
Can you recommend where online I can purchase the level sensor only?
Wonderful
Thxxxxxx for sharing
So my husband just installed a brand new fuel pump in my GMC Yukon 2004 and the psi's are at 60 runs wonderfully but the float is stuck do we have to drop the whole tank again is there a way around this may be a stupid question but if anyone's drop the tank before it's not the greatest and most pleasurable thing to do the fuel pump works great it's just a Float/ sensor is stuck
Is it the same for the 2004 maxima
@CarsNToys did the float sensor stop the car from running?
Hi! Thnks for sharing ur knowledge! I try to integrate car fule sensor with arduino(microcontroller) so I my question is . every car has same mechanism like this ? to measure there fule? I will B waiti g for Ur valuable Reply?
Some use a digital unit but for the most part many vehicles use the 'floater' design.
good video. thanks.
Welcome.
Could you please explain me how does that top plate works?
WOW, Where do you buy it? I can't find him anywhere. They Always sell me the full fuel pump.
Any idea what would solve the issue of the fuel gauge light on the dash? Mine has never appeared and when I refuel the gauge is really slow. 05 Impreza outback sport
hi there I have passat cc 2009
my fuel level sensor reading is between 50 to 300 ohms!
but not indicated on the dashboard
where do you think is the problem??
thanks
On my 08 Chrysler 300 I think my fuel gage is broke. It goes to half and stops. How can I tell if it’s the fuel gage or the fuel sending unit ?
I have a 2007 model Innova... The moment it starts after 4 to 5 acceleration this meter shows check engine... Also, the pick up drops drastically... Please suggest what could be the problem???
I'm looking for a 2011 Kia Sorrento fuel pump is it different I'm having trouble with my fuel level floater
I wish all vehicles had a access Patch or panel like this to get to the fuel pump
Long story short - 2006 Sentra 1.8L Had at least a year old problem and took it to a couple shops and didn't fix it . It was not revving up no matter if i floored pedal . It was gas pump and I went to junk yard got it for $34 including warranty . That was yesterday now running like a champ like new !! Yeah at very beginning suspected it might be pump but went with shop's recommendation . I trouble shooted it myself
What's a "gas pump"? I have an 07 Nissan Sentara and my fuel gauge keeps giving me inaccurate readings.
@@verinb9 I meant fuel pump. As for the rest of my comment. .a lot has happened since I first wrote here. Car's history is all over the place. I had a very long time problem and did replace fuel pump. Shortly after that , it was again having that same problem. I got another car. New car was in shop and I used the old Sentra. It was pretty reliable never experienced that same old problem which I've been dealing with for long time. Ran reliable for about a month. Then once new car was fixed I didn't use it much. Just used it today and still no problems. Kinda at a loss to explain it all.
Hey I did this test when I went from lowering it from high to low the reading was okay but everytime I do the test I get a OL for like a second a continues reading
The 2006 Buick Rendezvous that I was trying to find a video about doesn't have a panel that I can remove the fuel pump through, unfortunately.
Hello
I need your help, my Nissan Micra 1.0 k11, does not turn on the fuel reserve light, but does the indicator work?
Do you have any idea what the cause will be?
Thank you.
ayeeee a Z32. thats dope. i love my TT
Hi am having trouble after I open the top disc. Now it will not lock back down. It actually seems that the surround metal has expanded, and will not stay lock down. Instead of have a plate that screw down, they decided to USE metal DISC lock it. But what happens when the metal get stretched, it will not stay lock down I'm going to try to use mini c clamps to make sure the it stay lock down and will not pop open because of pressure or vibrations.
I have a question I tried to calibrate the gas needle on my Honda CR-V 2005 cause I was trying to replace a light 💡 on the creíste some how I ending up with the needle fell off on me I just put it back but it’s not accurate anymore
I have a 99 Lexus es300.. and the gauge would move super slow.. now it barely moves above half a tank.. and moves just as slow to decrease. Only time I know it’s full is the gas pump stops.. I’m thinking it’s the sensor.. it’s bout $163 since finding even a fuel pump assembly for this car even trying it under Camry can’t find nothing! It’s a literal pain.. guess I’ll have to get it. Don’t want to end up stranded somewhere.
How does one remove and replace the fuel lever sensor on a 2003 Honda Pilot? There is no tab to depress, and otherwise does not appear to be removable. Is this so for this car?
Hello, my Ford S-Max Titanium 2013 fuel indicator is electronic when it works, but when it arrives before halfway it stops and does not give a reading and remains off. Please answer me. Do I have a problem with the sensor or something else, even though I had a problem with the old battery amp? Thank you.
I have a honda crv 2007..when i fill up my tank the gauge (electronic display on the dash) show full and increase the miles left to run.. Problem is you might drive for 150 miles straight and not a single bar on the gauge will decrease and the miles are basically the same which is wrong.. Checked my fuel sensor and seems to work since the resistance is changing when i move the sensor up and down.. So my question is this? Is my whole console needs to be replaced or is it possible i have a bad ground circuit somewhere? And from where do i start to investigate?
where did you buy the level sensor unit itself??
im looking for one for the g37
Sometimes you have to purchase the fuel pump assembly. If you can't find one on amazon, ebay motors, etc...Nissan/Infiniti may be your last choice.
When I disconnect the fuel lines on a diesel before removing the fuel sending unit, will I have to bleed the fuel system after putting the system back together? (audi a6 quattro 2005)
No need
Where is the link for my Samsung Galaxy S5 phone app so I can use this gizmo?
Nice but I need data on a 2010 Prius fuel tank float gauge. Where is the link for my Samsung Galaxy S5 phone app so I can use this gizmo?
Lol.. Fuel gauge for a Prius
Will the reading be different for range if the fuel quality is really bad
I can't see how. The sensor is buoyant.

I need to change it in mazda cx7 , where I can buy the ful gauge?
Is this part in any way connected to the Fuel Level Sensor 2 on Audi? I watched your Tank System Malfunction videos & a Mieneke mechanic changed this part (pump)-which didn’t make the error light go off, then a 2nd mechanic (3rd party) replaced my Sensor B control module. Light went off for a second & came back on. Now Audi is saying it’s the Fuel Level Sensor 2, saying I’ll need to replace the whole fuel tank.
Where can I buy fuel pump level sensor ???
Thanks
same here, i can t find one anywhere; only complete fuel pump
i need help, my fuel gauge was erratic, so i replaced the sending unit and then it started reading full all the time even when it wasn’t full, so i replaced it again because i thought it was bad, same thing. so i replaced the whole fuel pump and assembly and it’s still stuck on full. all of my fuses are good and i even tried replacing the whole cluster and it still reads full. i have a 2012 sonata se
I got a p0461 and p0455 code on my cobalt. I just had the whole pump replaced last year. Someone said it might just be the evap canister needs to be replaced or cleaned out; however, sometimes I can't fill up properly. Not quite sure what to do. I have a hunch the fuel lines may have something to do with it also, but it's hard for me to test this stuff myself, right now, without a garage.
Not having a garage in cold weather is a killer. Have you tried testing the fuel lines via fuel pressure gauge? You may be able to rent one. Amazon has some low cost options.
Hi I have code P0464 on my 2000 nissan sentra I ready read en tell me my level sensor it's not working but it's work because i I see when I full mu tang ??? Do you think I have to renplace my level sensor ...
Hi, I have a 2001 Jaguar S Type, and the level sensor is bad. Do you know where I can find one, I checked on ebay but nothing. Don't know if the X type one Wil work. I live in the Dominican Republic, so it has to be on internet
Sure so smart 👊
Hello, I have a very weird situation if you could help. My 2010 Nissan Altima 2.5s has a crank won't start situation. It has P0463 and P0183. I filled my tank with 105% (more than full) and parked on a 10 degree inclined slope. I don't know if these two codes would cause my car crank but no start? Last time it had a starting sound for 1st second, then died on the 2nd second.
I checked battery - good. I pulled out fuel line before the injector, when I switch to on position, there were fuel shooting out. The fuse of the fuel pump is good. I even changed a camshaft position sensor, didn't help. I removed engine air filter, sprayed starting fluid, didn't work. Car is cranking, so I assume the starter is good.
What can the problem(s) be?
Thank you in advance!
I have a Chrysler 300 if my gas gage not reading gas do that mean i need a fuel level sensor?
I've just tested my gauge and I get a reading of around 4 when low and 80 when full... Should I replace the gauge? I have the 2010 X-trail T31

I don't see the link for removing the fuel pump?
do you have to replace the fuel pump as well or just the sensor?
No need to replace the fuel pump; unless the sensor is built into the unit.
Oh man i didnt test my fuel pump b4 installing
I tuk it fo granted
Cuz it wuz a new 1🤪😫😱

Can this cause your car to turn off on you once it’s on? I got a code for fuel temperature sensor P0183 and my car turns off on me when I drive it for a while any help please?
i keep getting feul temp and fuel level codes in our 2001 santa fe 2wd 2.4l manual trans, i have replaced the fuel pump but still get them. so frustrating
Where do you buy the sensor??
Would this be the same for a fuel temperature sensor a circuit is that where is located
Typically, yes.
Dose a fuel pump level sensor sell separate from the complete pump
they usually sell u together the whole sending kit

Hello I've got a VW Touran 2006 diesel fuel gauge not working change sender still not working fuel gauge on dash goes to move a little bit but then stops any idea
is the fuel level sensor also called a sender? i want to purchase the sensor but it seems like in the car's spare parts diagram, it is called a sender. Or maybe it is the wrong part?
conseguiste? tambien necesito el sensor
Hello my car is fortuner 2013 diesel 3.0 D4D manual gear , my fuel sensor is broken but I don’t know choose which number sensor , before I choose one but not okay
Any you could just clean it up and it would start working again?
My car reads the amount of gas but it takes like 30 seconds for it to move up when I fill it and when I'm getting to e when I'm driving giving it gas the needle moves up just a little like a cm then when I brake it goes down a cm what is that ?
Gravity moves the float. Really can’t do much ab tbat
Fuel pump was replaced and read has level for a week or so and went out again. Any help?
I’m new to this so I may not be correct. But I’m assuming there’s two ways to go about replacing a fuel pump? 1) Removing the bed completely 2) Dropping the fuel tank.
So when my car first starts it shows the right amount but as I drive it it goes down super fast and then after a while of it being warmed up it goes back to normal
I’m testing my fuel sensor and when ohmmeter reading reaches around 40 I get the continuity beep. Is that fine?
I think so. If there is no continuity I'm pretty sure you would see OL for open lead.
