Anyone have a Fuel Gauge Issue?
 

Guys I've only had my Z for 2 months and i filled up my gas tank a week ago and noticed the last light on my fuel gauge didn't light up. I thought maybe it didn't fill up all the way. But, I filled up again today and noticed it did it again. This happen to any of you guys? Know of any issues with the bulbs on the fuel gauge burning out?

The bulbs are LEDs so it would be unusual for them to burn out. I've noticed that my Z is a bit tempermental with how far the gas nozzle is inserted into the car when filling up. This is mainly an issue at the START of filling though, not the end. If you put the nozzle all the way in (hubbed), it will immediately 'pop' back to off when you start filling. You have to pull it back out a hair before it will fill continuously.

I suppose I'd first try to top things off...once the gas pump stops, withdraw the handle a bit and try putting in another half-gallon or so. If that doesn't light up the final light (far right) then you should just take it to the dealer.

The fuel/temp segments are NOT LED. They're part of the LCD segment, so it can't "burn out."

Thanks for the info guys ... I'm goin to try topping it off again the next time I fill and see what happens ...

The only thing I notice about my fuel gauge..........it blinks empty, often.

I just topped off my tank and all the lights light up. HTH.

The only issue I've seen is trying to read it in bright sunlight. That thing washes out pretty easily.

At 1400 mile I had a check engin light come on while out of town. Stopped in the area dealer they looked up the code and had no info on it. They then called Nissans tech support. They said It could be a fuel sending/pump problem. Told me it would take 6-7 hr to check out. Since I was out of town, I told them no way. They cleared the code and it hasn't come back on. It's been four days now, so who knows. Not sure if this helps or not.

As stupid as it might sound, make sure you filler cap is on well/correctly...I had a Z a couple of years ago that seemed very sensitive to this...apparently, modern fuel tanks are designed to maintain a certain amount of pressure and if the fuel filler cap isn't one properly, the pressure can't be maintained and you'll get the ubiquitous "check engine" light.

As to the fuel gauge question, mine lights up all the way if I fill up the tank all the way - of course, it might work well for me because I'm pretty anal about getting every possible drop in that the tank will hold - you never know when that last half-ounce will be the difference between rolling into the next filling station under power or having to push the car to the pump! :)

I have this too, where the last light won't come on. So far I have filled up 4 times and it has never come on.

Today I even filled up all the up to the neck filler (without causing an overspill on the paint too). It's not a big issue, especially since I'm use to it with the Harley. I never trust gas gauges. Pushing a 700 lb bike a 1/4 mile was not fun.

Maybe it's possible that there is some sort of limit switch that is not adjusted correctly. I would get the dealer to check it out.

This was very true of my 2004 Tiburon I had. If I didn't tighten the cap enough (until I heard one or two "clicks") the Check Engine light would come on. Got lucky once and it went off after a refill but usually I had to go to the dealer to get it turned off.

I believe I even failed emissions in VA. once and it was simply because I hadn't tightened the gas cap enough. Sensitive, indeed! ;)

This is not a good idea, as gas expands. Your owners manual will tell you not to do this as well.

Yeah that was the only time I risked filling up to the neck. I would hate to spill fuel all over the paint.

That happened once with the Harley. Freaking gas pump didn't auto-shut off and fuel dumped all over my hot engine.

No fires, just one pissed off rider, a hard lesson learned, and a couple of hours of clean up.

Thanks for all the help guys ... But after I posted this thread that day I was driving to get Sushi and watch the Laker Game, when I parked I turned off the car and then back on and the freaking last LED lit up :wtf: I'm hoping it won't happen again or else I'm going back to the dealership ... Y couldn't they jus make the damn fuel gauge a NEEDLE like to match the other gauges !!!

Doing that can "flood" your Charcoal cannister, get you a CEL and a No-start..

Happened to my daughter a few times with her Mazda 3 until the dealership told here what was going on..Stopping at the click off is the best technique..

That's usually caused by the automatic kick-off being too sensitive. Some stations aren't calibrated correctly for it, and they pop off easily.

Okay your car must have talked to mines because today the last light finally lit up too! Weird.

Or maybe Nissan read the post and uploaded a fix via bluetooth. lol

Usually when I fill up I FILL UP with every last ounce I can get into the tank so as to keep my fuel stops as infrequent as possible...of course, I usually don't fill up until I'm actually going somewhere and/or traveling so whatever gas is in the tank get's used pretty quickly (or at least steadily)...at any rate I've never had a problem doing it that way (maybe I've just been lucky). ;)

I filled up yesterday and the last light on the fuel gauge did not light. I drove back to work and let it sit after lunch. When I went home the last light was on and has been on. I think I will keep an eye on it.

mine has done this twice as well the light always lights up after i turn the car off and back on again... i have no clue why its doing this

Lolz ... 370's are psychic !!! Well, it seems like it's not jus our cars doin this so I guess we gotta keep an eye on this ... Maybe it's jus a sensitive fuel gauge sensor inside the tank ...

So did you bring in your car to fix the issue? Because I just fueled up again today it did it again !!! I'm pissed and ready to make Nissan fix this ... If any of you guys that are experiencing the same problem please let me know if you got this fixed and know why it's happening ...

no i didn't it hasn't done it in a while so im not too worried about it

Ok well I just spoke to my dealership and I will be bringing in my car next week ... I'll keep you guys posted on why this issue just in case it happens to you guys ...

Betcha they do more harm than good......This is really a non-issue.

Good luck (you'll need it)

Aren't these guys supposed to be professionals? You really think they'll mess up my ride to fix a simple issue like this? I tried ignoring it and hoping it would fix itself but that became wishful thinking ...

Assuming your average dealer tech is a professional may be a bit of a stretch from many reports here. They're going to have to dissasemble part of your interior to get to the fuel gauge senders as they are mounted in the fuel tank on both sides of the car (guys that have probably never taken a 370 apart before). It's not THAT simple. Personally I'd run a few bottles of Techron through your next few tanks of gas before I'd go that route. Techron has great success in scrubbing Fuel senders clean and bringing them back to full operation..It's worked for me and a bunch of my friends in the past,,

BTW, Senders are just simple rheostat type devices with a contact that moves up and down to make connections with the multiple contact strips and transmit electrical signals to the gauge and cause it to read from empty to full depending on the fuel level. Being submerged in fuel they tend to gunk up and stop reading correctly if good gas isn't used. The look like this:

I have just filled up my gas tank to the brim and my last fuel dot is not lit up. This happened to me last two times too. After driving lets say 30-40 miles, the last led becomes visible again (sometimes). Weird :ugh:

Good info DIGItonium. Your statement makes sense because sometimes the last dot did lit up after driving for a little while. Not sure what's the cause of this.

Yeah mines has been hit or miss these past 7 months. Most of the time it fills up to the last dot. Other times it looks just like your picture.

I am no master mechanic, however, maybe a fuse??

yup.. six miles driving into it, the last LED lit up :icon14:

I've had this happen last three fill ups! Tonight I decided to add another dollar and a half after the pump click off to see if it was a sensitivity thing! Well it worked!! The last light did light up!

I only run Chevron w/ Techron in my cars anyway, but I did try the Techron concentrate bottle two fill ups ago (what Modshack mentioned). Not sure if it did much.

Same thing used to happen on my Titan. The gauge would slowly rise from 3/4 to full the first 30 miles or so after a fill-up. I had the fuel sender replaced under warranty at the dealer but then it was even worse - after the "fix" it would go all the way to full as normal but then the tank would be empty at 1/4 on the needle with no low-fuel light. I ran out of gas on the first tank after the dealer "fix". Thanks Dealer!

So when the last light on the Z's gauge started doing the same thing on the Z (not lighting up after fill-ups) I listened to some other members here and went to Chevron for the next couple fill-ups (for the Techron). Hasn't happened since. Thanks guys!

The reason for this is that the last contact on the sender spends more time uncovered by fuel then any of the others. This gives corrosion a chance to build up. When you fill up, the connection for the last light is not made because of this. As you drive a bit the sloshing fuel moves the contact arm up and down over that last connection. The corrosion is scrubbed off anf the light illuminates. Again, a bottle of Techron concentrate at your next fill-up will go a long way toward keeping these contacts clean..

Same exact thing with me too guys... full fillup and the last light is not on. I'll drive around for a few miles and or shut the car off for a bit, turn back on and the last light is now illuminated. Not a big deal, but annoying.

I have the same issue. The light have been out for about 2 months. I dont know whats going on. Its annoying at first but im use to it now.

WILL DO! thanks MS :tup:

It just happened to me too..., first time. I am about 8k km on odo. Two LEDs dont lid up. :shakes head:

I always fill it up to the neck...., it never happened b4...., I will try the one click method! :rolleyes:

so any final verdict on a cure for this problem? mine started doing that yesterday. since then i topped it off with gas twice and that final led just wont come on.
