Prius Plug-in 2012-15 :: Fuel Gauge Malfunction - Calculations Accuracy Extent?
May 6, 2012
I filled up for the first time yesterday after driving 1,039 miles. I had almost forgotten how to do it. Anyways, the reason I thought I needed to fill up was that the gas gauge was down to one bar. However I was only able to add 8.3 gallons. I thought 1 bar=1 gal but that turned out to be inaccurate.

I pumped 7.4 gallons of gas into my prius plug-in and the fuel gauge does not register the gas going into the gas tank. The gauge was down to four bars and after the gas was put in, it did not change. The trip odometer has me at 114 miles left, on what I measure as 10.4 gallons. Toyota care was contacted and is trying to figure out what to do next ad are two Toyota dealerships who have never heard of such a thing before.

I have had my PIP for just about one month now and I have only filled up twice. This car is awesome! I noticed when I filled up the last few times that the last block on the fuel gauge started blinking and my miles to empty reading was pretty low. However, when I filled up the tank, it only took around 9,2 gallons. Doesn't this car have a 10.6 gallon tank?

I had a 2006 Corolla S 1.8L automatic with 232,000+ miles that was taken away too early by two other cars making a sandwich out of it. It was still getting 32 -37 mpg consistently and about 370 - 390 miles per tank at least before I'd look for gas. I just replaced it with a '13 Corolla S 1.8L automatic and average out near 28 - 32 mpg (but it's winter). My issue is the readout on the gauges. I've got a 120 mile round trip for work daily (all highway). On the way home yesterday, gauge showed 1/4 tank and distance said 85 miles (enough to get home).
At about 26 miles left, yellow light came on. At gas station 19 miles left til empty (or so I thought), yellow light shut off and gas gauge went back up slightly off E. Filled her up and it only took 10.2 gallons after topping it off a couple times after the pump shut off. Distance traveled was about 320 miles on that tank so around 32 mpg. I'm o.k. with that but I thought these had the 13 gallon tank like my '06? Were there still 3 gallons in there and the sending unit may be bad or am I missing something? BTW car only has about 6600 miles on it as of right now.

Me and my fiancee have a 2013 Camry SE and we've been having issues with our fuel gauge... It randomly will just stop working... First time it happened she just got in the car from work and it was at empty. When she got to work it was at half a tank... It took about 20-25 minutes of driving for it to slowly reach back to half a tank.... What could/would cause this malfunction?? And then today on her way to work it did the same thing..

Just wondering how accurate the digital gas gauge on the Prius c is? My current 04 Prius has a notoriously inaccurate gas gauge: It often gives me an incorrect reading showing much less fuel than I actually have. It is even worse in the winter.

Display says i have only used 5 gal of gas, but i only have two blips left on my gas gauge. Something has to be wrong.
Wonder if something is wrong with my tank.

Just wondering about the "miles to empty meter", should I disregard it when I have high mpg? (50-60 mpg)

I've recently purchased a 2007 Prius and have been tracking my gas mileage. I've been comparing what the computer says and what I get by dividing the miles since last fill w/ the number of gallons to fill. I always reset the computer and have always let the tank get almost empty (flashing fuel gauge). I consistantly calculate 2-4 MPG LESS than the computer reports. I talked with a friend who has a (I think) 2006 Prius and he does the same but his calculations and the computer usually within a few tenths of a MPG. I took my car into the dealer today for the accelerator pedal recall and asked them to look at the MPG. They could find nothing wrong and said that was "normal" I'm not convinced... What do the rest of you see?

how much fuel is consumed during a typical warm-up period for the Gen III? I realize there are variables related to ambient temperature etc..
my interest is to get a baseline consumption figure to compare warm-up saving devices/techniques against.

In the past I have had my fuel Gauge go down 1 bar after about 60 miles traveled. Since my last fill up my fuel Gauge has only gone down 1 bar (9 still ON) after 185 miles travel. The gauge appears to be struck with 9 bars ON after 185 miles traveled!, Any fix to a stuck fuel Gauge indication?

I have a 97' F-150 4.6 L and I've been having some fuel gauge issues.... I filled up my tank up and I drove it 130 miles and it still said full tank... even when I had 1/2 I would start it and every time I started it it would jump up all the way to full and slowly drop down. Then randomly last night it started working... I noticed as I hit rough patches in the road and bumps it would usually fluctuate, but it would also fluctuate up... It read I have 3/4 tank last night and I go to start it today and its back up to full! I don't understand... Wouldn't a bad sending unit just stop all together?

After my 25k service it seems the timer scheduler when the square button is pressed/held flashes at 7am. When i press the H button the hour advances to 12am then closes. I want to start the charge at 12am and finish at 5AM. The timer windows closes when i move the finish hour to 12am and then my regular clock hour changes. It used to be when i pressed/held the timer button the start time would show at 12 am and after setting it would go to the finish hour.

I've done 3 oil changes since picking up my 2012 Lariat 5.0 a little over a year ago. And I've always questioned the accuracy of the oil dipstick - seemed to always read 'low'.
I just changed oil tonight (Motorcraft 5w-20 semi-synthetic), and I measured the oil that I drained out - just about right at 8 qts. I put in 7 qts and 24 oz (about 1.6 - 2 oz over the 7.7 qts that it calls for) and the oil barely reaches the low level on the dipstick.
I guess between what I drained out and my current oil level reading, my dipstick is not accurate.

I bought a 2013 XLT 4X4 wiht 5.0 V8 about 3 months ago. I reset the computer when I first bought it and it shows an average of 15.7 MPG. I have also kept records of all fuel purchased and my actual mileage is 15.2 MPG.

Yesterday, I was driving home in EV mode, PHEV on, about 80°F, no hills, not accelerating, SOC about 4 bars, about 1/2 mile out, when it dropped out of EV mode, and then I got the red triangle and the check engine light. Today I grabbed the code with an OBD2 reader, and got this:
Freeze Frame Information:
1. DTC for which Freeze Frame was Stored - P0A92.
2. Engine Coolant Temp - 138.20 °F.
3. Engine RPM - 1,888.00 Rpm.
4. Vehicle Speed Sensor - 14.91 Mph.
5. Intake Air Temperature - 96.80 °F.
6. Time Since Engine Start - 101 Sec.
7. # Warm-ups since DTC Cleared - 74.
8. Distance since DTC Cleared - 706.50 Mi.
9. Control Module Voltage - 13.69 V.
10. Ambient Air Temperature - 80.60 °F.
11. Accelerator Pedal Position D - 30.98 %.
12. Accelerator Pedal Position E - 46.67 %.
13. Time since DTC Cleared - 30 Hr32sec.
Does this happen because it's in EV mode? Do I just have to put up with it every so often? (This is the second time it happened.)

2 weeks ago, I noticed the fuel gauge doesn't return to EMPTY when the engine is off. I didn't worry much as the actual movement of the gauge seemed accurate as I was using up the fuel. I figured it might fix itself during my next fuel fill up. Nope....continued staying at the fuel level and not returning to EMPTY. A few days ago, I noticed it went back to EMPTY when the engine was off, but it took approx. 5 minutes. Now it doesn't go back to EMPTY.

I was heading to the gas station with one bar on the fuel gauge. When I got there to fill up I had two bars, same Miles To Empty (45). What would cause that?

I have a 2012 Buick Enclave that the fuel gauge fluctuate. It is not in sync with digital readings. When parking down hill the gauge goes to full. After driving a while the needle will move up a little. Even when on level ground it will fluctuate.

The outside temperature is reported inaccurately by your C? I now automatically deduct 5 degrees from whatever my C tries to tell me is the temp. I may mention this at my 5,000 visit to the dealer because I'm wondering if the sensor is placed too closely to something creating warmth. But....it's definitely reading too high.
