Lexus GX 2004-09 :: Fuel Gauge And Range Readout Not Working Intermittently
Sep 23, 2014
We have an 04 GX-470. Most of the time the fuel gauge and the range readout work OK. However, sometimes, the fuel gauge works, but the range shows 0 miles, or they both don't work - fuel gauge shows empty and range = 0. My wife says she thinks she's seen the gauge = empty but the range still showing xxx miles - I haven't seen that.
We've been to 2 different Lexus dealers, paid for diagnostics at both and gotten no fix. In fact, they have both said they can't find anything wrong.
To my way of thinking, these would both get their initial information from the same source - some sort of sender unit on the fuel tank. However, as both gauges do not always go out together, I'm inclined to think that this probably isn't the cause. I would think that the range readout comes from some calculations done by the onboard computer.

We've only had the car for a week but I'm puzzled by what I'm seeing for the mpg on the screen. At no time has the screen indicated an average mpg of outside the range of 44.7 to 45.0 mpg. This is despite filling it up, resetting the trip meters and immediately heading up the Cajon Pass twice while the instant fuel economy indicated 25 mpg or less. I understand the inconsistency of calculating at the pump because of the bladder but doing that has worked out to 2 fills in the high 30s, one in the high 40s and one of 53 mpg. Yet the car still reads 44.7 to 45.0.
It's not a big thing because I don't depend on it; I tend to fill the car when it goes below 1/2 full and over time I will have enough pump calculations to give me a fairly accurate depiction of my average mpg.

How accurate is the mpg readout on that display screen on the Prius. How is it measured.

Just traded in a 2012 Nissan Sentra SR on a 2013 Hyundai Santa Fe Sport and have a question about the gas mileage.
My Sentra always read 28+ MPG, but it was a known issue that the reading was almost exactly 3 MPG off; thus, I was hitting about 25 MPG most of the time. I could typically get by for a week and a half, sometimes two on a single tank (which was about 11 gallons).
I took the Santa Fe home on Thursday night, filled up from the dealer and reading a range of 384 MTE. As of tonight (Saturday), my fuel meter is reading two notches over the halfway mark and the range has dropped to 232 MTE. I haven't driven anywhere near 150 miles since Thursday, FYI.
The MPG on the Santa Fe started t a measly 12 MPG when I left the lot, most likely due to sitting and idling and lots of stop-and-go driving on test drives. I've since managed to get it up to 22.2 MPG (and feel confident it should eventually read about 25 MPG, about the same as my Sentra). Even though the MPG reading is going up, I feel like I'm going to be filling up the tank again without hitting a full week of driving (and this is a bigger tank than the Sentra). I'm not getting the difference. Is there an issue that I'm missing here? After checking in with the dealer that the previous owners used for service to ensure there were no red flags, they did tell me that it had an active bulletin for a software update. I've read in other places here that this update can have some effect on the MPG. Any thought on if these things are connected?

Ok, had the prius c four for a few months now. What is up with the gas gauge? When I get down to one rectangle my cruising range drops to like 9 miles. I got gas and put in 8 gallons, which means I had 1.5 gallons still. Why is it showing such low cruising range mileage? Looked through the manuals by couldn't find anything useful. Also, is there a way to see exactly how much gas you do have? The rectangles seem a bit arbitrary to me when it comes to representing an actual amount of gas?

I already searched and seemed to only find info about, no backlight but lcd readout was still working. My backlight reacts to the lights being turned off and on; so I know it works but just no numbers. I noticed it on the way to work after the truck had been sitting in the hot sun for a while but When I got off work after dark around 11:00pm it worked all the way on the drive home, but I went to grab a bite and it no longer worked. I figure it could have something to do with sitting in the heat? It's the stx cluster with only the speedo and no tac if that makes a difference. I really don't want to have to drop cash on a new cluster.

Yesterday my fuel gauge stopped working it is pegged all the way to the left. I filled up the truck no change. Got home and my garage door opener would not work and when sitting in car the map lights wont come on, the overhead lights work when you open the door. Cannot find any reference to what fuse any those items are connected to. is there a fuse for the fuel gauge?

My fuel gauge is not working properly. I ran out of gas while going down the road with the fuel gauge still at 1/4 tank. What do I do to fix this problem?

I have owned the car for about three weeks and I have noticed that the fuel gauge will sometimes go to empty or should I say will not go up to the fuel that is in the car... It always stays empty... At E, why? I have tried tightening the fuel cap for multiple times. What kind of parts should I replace from Sewell?

Is there a digital readout gas gauge so that when I am driving down the road I can see exactly how much fuel is in the tank

Why External mirror command and seat memory don't work normally on my GX 470. Some time is work and sometime not. Maybe some fuse or relay are bad now...

Fuel pump in my Volvo 940 has been replaced twice. Since then, my fuel gauge has not worked right and I have had to pump gas about every 120 miles so that the fuel pump would work right. I would fill the tank, and 120 miles (about 5 gallons) later the fuel gauge would indicate about 1/4 tank of gas left. That's when the fuel pump begins to mis-behave. If I make a sharp turn, it would stopped pumping for about 2-3 seconds. If I continue to drive at that level of gas. I can avoid all these problems by keeping the tank at least "half-full", that is, by pumping every 120 miles. The car was totaled by a hail storm and I bought it back for $84. I like to operate the vehicle for as long as I can, one day at a time.

How many miles can get on one tank of gas. Is it between 300-400 miles? I know hills and city driving makes a difference, but I'm trying to get an average.

My low fuel indicator isn't working and I'm wondering if there's a way to initiate a bulb check without OBDII?
Looking for options prior to pulling the cluster to look for a bad bulb.
Ran it pretty low this morning, distance to empty indicating 24 miles and fuel gauge on "E" - would think it should be on.
Realize it may not be a bulb but that's an inexpensive fix.

My 2007 ES 350 will chime if the car is on and the door is opened. It will also warn you if the car is on and the electronic key becomes out of range.
One day both of these features stopped working. Everything else seems to be working just fine.

I have a 2004 F150 XLT 5.4 L 79,000 miles. Yesterday i was driving home turned a corner and the low fuel light came on and the fuel gauge is well below empty. I had approx 1/2 tank of fuel when it happened. I have since filled tank all the way but the gauge will not move and low fuel light stays on. Everything else is working fine! I have never run the truck low enough on fuel to make the dummy light come on.....

I have a 2002 Prius, and I have been struggling trying to get it fix. But it's either one thing to the next without completely knowing what's what. Recently, the right front bearing and the left rear bearing, both front struts/shocks, right balljoint, and two front brakes were replaced.
Before these replacements, I had a P1436 code for the valve which was lube but nothing happened. Then after replacing the front struts/shocks, turn the car on for a test drive, brake light and check engine light came on, speed odometer it not working. I used the OBII scanner from autozone and got P0500 said: vehicle speed sensor A malfunction.
