Prius C Fuel :: Low MPG Reading - Reset?
Mar 21, 2012
I bought a Prius C package 4 in Silver with Black interior with 16 inch allow wheels yesterday, I really like the cool technology and the look of the car. I bought it from a dealership roughly 160 miles from my home. Once I purchased it and was driving back on the Florida Turnpike, I first started of getting 43mpg, I was in the higher green area of the Eco meter, basically I was pushing the gas pedal and it was reading roughly 90 percent of the Eco meter is being used, I was driving at 78-83 mph. After an hour or so, I checked again and to my surprise it was reading 32.2mpg, I was really concerned, and slowed the speed, but it didn't change the mpg at all. After another 15 minutes, the mpg raised .1 every 2 minutes or so until I got home and parked my car I was getting 35.8.
This morning I woke up, got into my car and started driving for about 20 minutes, it is still reading the same 35.8. This is with me driving around 50 percent of the Eco meter
I'm concerned, is there something I'm doing wrong, do I need to reset this mpg, if I do, how do I do that.

Every time I turn the car on, the "from start" fuel economy reading resets to 15l/100k. After driving for a while it goes down to 4l/100k but then resets back to 15 once the car is turned off. Is there any way to get it to stay at what it finished at?

Driving on my original tank from dealer today from Upstate NY to NYC. On the way my C had 4 bars to begin then went to 3, then 2 after about 90 miles of traveling at avg of about 55mph. I watched the cruising distance go down to 1 but I still had 2 bars on my fuel gauge (and my crusing distance was conservative compared to my mpg reading the whole trip, which was hovering around 58mpg).
The gauge went from 2 bars to one flashing bar in about 1 minute. I pulled into a gas station about 2 miles ahead and put in about 5 gallons... this put the fuel gauge up to 3/4s or about 3 bars above the halfway mark. What gives? I know there are fuel gauge issues but I thought with two bars I would have had plenty of time before I needed to fill up on these roads with these mpgs.

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?

How to reset the trip gauge on the dash? I would like to reset it to figure out what kind of mileage I am getting. I am a new owner of a 2010 Prius III.

I'd heard that the new Prius V would give you stats on your latest trip. I see where it will tell you how long you've driven, but I was under the impression that it also did your MPG for the latest trip too?
Also, my 2008 would automatically reset the trip odo upon fill up. Not the tripA or tripB odo's, but the one on the consumption screen. Does the new one do something similar? I new at every fill up that I would reset the MPG's for that tank whenever the miles reset. I can't find an analog to that in the new screens.
How are people calculating MPG's per tank, computer wise?

Why does the fuel usage (MPG) stats reset after filling up the tank??
Can I set it so that it doesn't do that?

Not the usual. I stopped on my way home to get gas tonight when the gauge was showing one pip. Naturally it wasn't low, but I'm used to that.
The odd thing is that after I got in the car and turned it back on the gauge stayed at one pip and the fuel display on the multi-function display didn't reset.

Coilpacks get 12V during ACESS, 9V when cranking. Crank sensor gets 10V, and VAG reads RPMs on crank, but no spark, no fuel.

I purchased a 90 Suburban and the fuel gauge reads low. I then changed the fuel pump and sending unit. The fuel gauge still reads low.
Then I noticed that all the gauges read low. Temp is low. Oil press is only a quarter up, the ammeter reads zero.

Having problems with the fuel indicator not reading full after a fill up. I have slowly filled my 2012 Passat TDI SEL till I can see diesel in the filler neck and the gauge still only shows 7/8 full?

I have a 1999 GMC Yukon SLE. I've recently noticed that I appear to be running out of gas at the 1/2 tank mark. When I go to fill it, it seems I really do still have 1/2 a tank of gas (so it doesn't seem to be just a bad gauge). As long as I keep the tank above 1/2, everything is well. What might be causing this?

When I start the car the fuel gauge sometimes goes past F and interferes with the water temp gauge. Also noticed recently that the RPM is not reading correctly.

i own a 67 old cutlass supreme and the fuel gauge, as you turn off the car goes down to 3/4 of a tank, when you start it up it goes to full. But the car is really empty! That is the only reading I get, no matter how much gas I have. I replaced the sending unit and I cleaned the ground wire, it still does the same.

Occasionally when i start my Ex, there will be NO tach reading (0 RPM) and NO fuel gauge reading (E). The Temp and Oil gauges will work fine though.
After a min or so, they come to life and move normally. This happens intermittently.

As title really, it's a 1997 K2500 Suburban 4x4 auto 454. I haven't used the sub for a while but got in it the other day and it fired up all fine and I then looked to see what fuel I had left only to see the needle right over to full. Well I know it is nearly empty and I've never had the guts to fill the thing or should that be had the funds to fill it to the top, so know it is wrong. I got under the truck and unclipped the rear most wiring connector just infront of the fuel tank but the gauge still reads full. I suspect either the gauge is faulty (so is there anyway of checking) or the sender in the tank or wires in the tank have shorted (again anyway of testing without removing the tank).

I have a 2007 Sante Fe with the 3.3 engine. Having a problem with the Fuel gauge not reading correctly and a check engine light. The engine code indicated that the problem was with the sending unit in the tank on the "A" side (behind the driver). I checked with Hyundai and with a tech line service and they indicated that it was a common problem and I needed to replace both the "A" & "B" units to correct the problem. I did that and cleared the codes and it set another code indicating that the "B" unit was the source of the code. I pulled the "B" unit again and checked the wiring and the problem still was there. I switched out the units on the "B" side again with the old unit and the problem is still there.

I've had an ongoing issue with my fuel gauge reading incorrectly, and now I'm trying to fix it! Basically, it will change all over the place while I'm driving (not erratically, but definitely moves occasionally). I recently fixed my overhead display, but the "miles to empty" display doesn't seem to be very consistent. It will read 450 miles to empty, and then the next time I look at it, it will have dropped 100 miles or something (after minimal driving).
So I'm wondering where I need to begin looking to fix this problem. I've replaced the dash cluster using Circuit Board Medics, so I'm fairly confident that's not the issue. I've read that it can be the fuel pump or the fuel tank sender, but how to check if these are actually the problem or how much time it will take. Luckily, I've never run out of fuel and been stranded, but I need to fix this or it's only a matter of time!

I just filled up my gas tank and when I turned on my car the gas light turned on and the needle read empty. But before I put gas, the gas light wasn't on yet and. Was at 1/4 of a tank. Maybe I filled it up too much and it'll resolve itself after the gas goes down?
It's a 10.5 if it matters.

Just changed the fuel filter in my '04 6.0, no issues worked just like normal, filter primed truck started, great. Well now my fuel pressure gauge is reading dead 0, I know that can't be right because the truck is running, but noticed my fuel mileage seems about 2 mpg lower all of a sudden. Had R&R Injectors installed about 40k ago, figure it's just a bad gauge but wanted to check and see before messing with the frickin wiring. Also, have had a lot of pressure buildup in the coolant tank, has had head gaskets and studs, anything else it could be besides head gaskets? Have had a lot of wiring issues with this truck from the previous owner....

In Menu -> Info Phone -> Fuel Consumption
How can I reset the fuel consumption?
I couldn't find it on Owner Manual...
