Fuel Gauge Issue

Jme370 · 11-03-2009, 01:30 PM

I just started up my Z and the fuel indicator shows no lights (empty tank). My distance til empty was flashing at 270 mi and my check engine light is on.

After driving 5 miles, the range dropped to 170 and the warning light is still on. I checked the gas cap. It is on tight. I tried power cycling the car a few times, no dice.

Has anyone experienced this with their Z? I did fill up with Premium Citgo gas last night. Thanks.

It sounds like the ECU isn't getting a reading from the sender unit anymore. It could be a bad connection in the wiring harness or the sender completely died (rare). I've had them get stuck before such that they show a 1/2 tank when it is actually empty but never seen one lose connection altogether.

Not to make fun of your plight but that might be your problem... "Chavez gas"...

LOL. My tech at Nissan said the sender unit is faulty or a bad connection. He's leaning towards it being a bad unit. Unfortunately, since this is a new car, even though the active code thru diagnostic is a common problem with other models they must spend hrs troubleshooting it for Nissan to warranty it. Also if it does require a new unit, Nissan most likely has not started making them yet as was the case with my seat heater that never worked from delivery. I am currently waiting on Nissan to make a spare seat to replace it.

This is starting to sound a lot like the reliability issues that caused me to get rid of my 350z.....

Nissan USA confirmed today that my car is the first 370 to have this problem reported. I am sure it won't be the last. Whoever it happens to next can thank me for letting Nissan spend many days working on it so it can be troubleshooted quickly in the future! haha

my fuel light issue is different, but here goes the last few fill ups the first led (when full first led) won't light up and some times the 2nd one either not a huge deal just b@#$%ing i guess but anyone else have this ??

i got the exact same problem, it irritates me, cuz i think the tank isn't full, then after a min or two of driving, all the lights light up and shows a full gauge.

I too have this minor irritation.

Yeah, I'm having a similar issue, but for me, it's my last led. It just stopped lighting up around 3 fill-ups ago. Somewhat annoying, but I guess I'll just live it it for now.

That happened to me back in October. The first light would not light up after a full fill. Lasted two tanks and hasn't recurred. I guess it healed itself.

It will stop again, just like mine and all the others.

I have the same problem! I thought of having it fixed but never did.It just a pain.

I think that digital gas gauge looks out of place, they should have put a normal gas gauge. The Mini gas gauge is similar, looks like a flower with each light a flower petal... Really gay not very accurate at all.

Red370 · 11-04-2009, 11:26 PM

nothing wrong with mine, but I tell ya, 3rd dot doesnt last more than 5 miles before it drops down to two, pisses me off.

Jme370 · 11-05-2009, 07:27 AM

The low gas light does come on very early. It is very misleading as you can still drive fort a while although I don't recommend it. As far as the first LED not lighting up until you start driving, that could possibly be the fuel injectors?? Not sure, but thats the first thing that came to mind?

My car is still in the shop, hope to hear something today on when I can return the Rogue and get my Z back!
