Oh no not another fuel gauge issue!

2004YZFR1

It seems like all of the new Nissan cars fuel gauges aren't accurate. My 09 370 and my wife's 10 Altima set coupe do the same thing.

Assuming the new sensors are good, sounds like high resistance between the sending units and the ECM (or wherever the analog signal goes). Could be a bad ground, dirty connection, frayed wire, &c.

Hopefully it's not a bad ground or frayed wire! Flammable liquid and electricity, doesn't seem like a good combination.

I'm going to try to keep it parked as much as possible until Tuesday.

Unless the bad wiring (assuming that's what it actually is) is inside the tank (all that's in there is the sensor/pump and you have a new one) or you have a hole in the tank (you'd probably smell it if so), the chance of explosion and/or gasoline fire should not be not any greater than normal. There could be a greater chance of a wiring-initiated fire (eg, under the carpet), but the fuse should blow before things get too hot. But, yeah, since gasoline could be involved, it would probably be a good idea to limit how much your drive until you find out what the problem is, just to be safe.

Good luck finding/fixing the problem and let us know what you find out.

Edit: Keep in mind that I'm just making a (educated) guess about the problem being a high-resistance circuit and the risk of fire/explosion may be much greater or much less than I portray above. It's probably not a safety issue, but better safe than sorry.

only issue I have with my guage is the last bubble doesnt show up. but then I put some injector cleaner, or octane boost in it and for whatever reason that fixes it for like 5-6 fill ups. Dont ask why, I have NO IDEA why it works, but it does consistently. renewable temporary fix lol. my 09 did the SAME thing.

Mt Tam I am

My 09 is not problematic.

Use your odometer in the mean time. 200 miles around town and refill again. Always fill to top when without a gauge. Good luck.

Our gas tanks have 2 floats in them. One mounted on the fuel pump sender housing right side, and one on the left side on it's own bracket. So our gas gauge is gettings readings from 2 different places.

I've had this problem too but after the first shut down and restart, it comes back as full.

Ayooooooo! I agree with the no issue, wasnt even thinking about that. I dont look at the fuel guage cuz I dont care about it.
