Possible problem with lcd readout (fuel gauge)...

[Nissannate25]

The past two times now that I have filled my Rogue up, there is still one lcd bar missing after the fill-up. Pretty much, the readout is showing a full tank, minus one lcd bar. The first time it did it, I just figured it something was messed up bec. it has been redic. cold here. Now that I filled up and it did it a second time, I'm starting to think there is something wrong my Rogue.Anyone else had this problem, or similar issues?

I see the same thing after a fill-up but after several minutes the gauge does show 100% full. I assume the sensor is a little "slow" determining the level.

Hi,

You have several threads about that already. I posted all the links below and you should be able to see if it is the fuel gauge sensor or the sending unit the culprit in your case:

Hope this help.

Mine is doing the same thing, with the added enjoyment of fuel levels varying between 3/4 and full at various times during the trip LOL. I have taken it to the dealer and have had both sensors replaced. The AWD models have saddle tanks that straddle the rear drive shaft with a siphon tube between them. One side has a fuel pump/sensor combo, and the other just has a sensor. Replacement of these didn't help.Tuesday I am taking it in and they are replacing the fuel gauge cluster. They were told by Nissan that the fuel signal from both sensors bypasses the BCM(?)computer and feeds straight to the smart fuel gauge cluster. I am hoping this works. My Nissan dealer has been great to deal with and they are really trying to solve this problem. I'll tell you if this works.

Thanks for the links, I should have searched myself first before posting. I'll see how it does over the next few fill-ups and if it keeps up I'll take the rig into the dealership and let them wrangle with it.

Just to update the repair of my fuel gauge. The new fuel gauge cluster didn't fix the problem. However I mentioned to them that I had read on an internet forum that several people had the same problem and they repaired it with a software update to the computer module. At first they told me that there was no update, but later checked on the internet and sure enough they found not only the solution to the problem, but the number of the Service Bulletin. They got the update from Nissan and updated my computer module. PRESTO....The fuel gauge works perfect now. If anyone has this problem tell them about the software update and insist that they search for it. I can't believe that they spent thousands of dollars on parts and labor before they tried the simple software update. But then again, they were never advised by Nissan Technical Services about the Service Bulletin.

There is a tech bulletin. From the Official Rogue FAQ:

Quote »NTB08037 - SB 08 Rogue; MIL Light On DTC P0463IF YOU CONFIRM DTC P0463 (Fuel Level Sensor Circuit High Input) is stored in the ECM and there are no other vehicle driveability symptoms, ACTIONS: Confirm this bulletin applies. Check and compare your Current ECM Part Number to Table A on page 3. If that part number does not match one in Table A, this bulletin does not apply. Go back to ASIST for further diagnostic and repair information. See this bulletin for further detail.[/quote]I have read through the entire bulletin and they do not describe the symptom ie. erratic fuel gauge readings. Only if the fault codes appears, reprogram the ECU. The reprogramming is for AWD models only. FWD models are not affected.

I will call the Service Manager tomorrow and ask him for the exact number for the document that he used to determine I needed to have the software update. If nothing else it should give someone with this problem some specific information to give to their service department.

My dealer, Ron Sayer Nissan in Idaho Falls, was great to deal with and really stayed with the problem until it was resolved. It was -22 degrees F when I took my Rogue into the dealer on Tuesday at 8:00 in the morning, and the service manager came in early to warmup the loaner car for me......Wow.

[Nissannate25]

Mine is still doing it. I filled up last night from half tank, still missing one bar on the gauge. My next oil change isin't for another 900mi or so, I'll have the dealer fool with it then.

I called the Service Manager and talked to him. He told me that the bulletin you quoted was the one that led him to reprogram my computer. I guess maybe erratic fuel gauge readings, and one bar short of a full load should be added to the symptoms.

As a side note, when I said I had erratic fuel gauge readings, I didn't mean that the gauge would bounce all over during operation. I meant that sometimes it would gain fuel level after I operated it for awhile, then later loose some level. I'm sorry if my description was misleading.

[philipa_240sx]

The TSB addresses a fault code condition, not errors in the fuel reading. I am having a hard time understanding why an ECU reprogram would affect the fuel sensor. Especially since the fuel level sensor is connected directly to the meter. The only thing the ECU does is provide a fuel consumption rate signal (for mileage calculations) and a vehicle speed signal.

[JacintoRogue]

I have exactly the same problem. The fuel gauge worked perfectly for eight months; now, it refuses to ever register the uppermost lcd bar. I fill up...past the first "click" from the fuel pump, and now the fuel gauge registers full, minus one lcd bar. What was the fix? I read all the posts and links, and I will be advising the service writer of the problem at the next oil change.

I have the same issue, but I don't think it's a problem with the gauge. If you pay close attention to whether your Rogue is precisely level while at the pump, you will probably notice that there is a slight incline one way or the other. If your car is even modestly inclined toward the gas fill-up side, the pump will sense the tank is full before it gets full. See rudimentary pic below:

NTB09-009 Service Bulletine2008-2009 NISSAN ROGUE; FUEL GAUGE DOES NOT READ FULL, OR SLOW TO RESPOND• Fuel level gauge does not read full when tank is full.OR• Fuel level gauge is inaccurate or reads erratically.

This will answer all the questions.

So does the Service Bulletin mean Nissan will fix this problem?

[philipa_240sx]

I have the bulletin. It's a warranty repair. Nissan will replace the sending units (one unit for FWD models, and two units for AWD models). Others have had this done with no improvement. Perhaps Nissan has redesigned the part?

[IdaCrue]

When I reported that my Rogue responded to the computer reprogram I didn't know that it would last approximately 3 days. I filled it up again and the fuel gauge read full minus one bar. I talked to the service manager again and he told me about the new TSB, and is checking with Nissan to see if the two fuel sensors he replaced in my car were the older defective ones.He called the other day to update me on the progress. He told me they will probably get two new sensors (again) if they find out that the sensors they did use were older defective ones, and the new redesigned??? ones are available. I am soooo glad this is under warranty.

off topic here. when i had my 02 altima, they would send me letter for recalls. Do they mail these bulletins out to owners too?

[kerrton]

No, these aren't recalls, they're service bulletins for the Service Dept. guys to address your problem if and when you come in and ask for Service.

[Nissannate25]

Mine has been a bit better. Still right after fill-ups doesn't register as completely full, but after driving a few miles it will show all lcd bars. Idk though, it seems on and off, it swings between showing full and full minus one bar.So idk, I'm just going to see what it does in the next few weeks and if it's still at it, I'll have the service dept. take another look when I get my 1st oil change.

[poconosmama]

Im so glad I found this post. Im actually having the opposite problem. I filled up with gas Sunday, and since then my gas pump light is on, and it shows I have NO gas, and the DTE is blinking. Calling service today, definitely a safety hazzard thinking you have gas when you dont:)

[IdaCrue]

Well the car is going back to the shop on Monday. I got a call from the Service Manager today and was told that one of the fuel sensors replaced in my car was not the newer updated one (I have the AWD with 2 sensors). Anyway, I'll report on the sucess with this latest attempt to correct the problem.
