For each number the computer says is there an exact match to what it means for computed. For example if the computer says 50mpg does that always calculate to x number calculated????
View 10 RepliesI've recently had the chance to buy some 'real gas' on a few fill-ups, Canadian gas without ethanol. The graphic shows that I'm getting about 50 mpg on regular E10, but about 58 mpg on the no-ethanol gas. Since E0 has only about 4% less energy than regular E10, getting 15% better mileage doesn't make sense purely from thermodynamics.
Does the Prius computer might be programmed for E0, and therefore possibly doesn't do as well on E10? And if so, can we re-program the computer?
I kept a record of every drop of fuel used in my 2008 Gen II Prius. It was easy with only two simple screens: Energy and Consumption. After writing down the numbers I reset the Consumption screen at every fill up. I entered these into a spreadsheet that did a bunch of calculations telling me all kinds of interesting things.
Now to my new 2014 Prius v Two. I'm confused regarding all the new information available. (A good thing) Which screen and number am I looking for that is equivalent to the Miles and cumulative MPG on the old Gen II?
Would like to sort this out before my first fill on the new car.
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?
View 14 RepliesMy 2010 Prius just turned 11,000 miles. Recently with colder weather it has become a rattle machine. Last winter it did not rattle at all. I then rode in my friends 2007 with 115,000 miles on it and it was still solid and tight on the same cold weather day. Did the Gen II have better build quality with fewer rattles?
View 11 RepliesIm very happy with the Prius that I have a 2010 V, its loaded with all of the options that were available at the time and I get a true 43 -46 mpg with my driving style and daily commute. The Prius averages more than twice the mileage I was getting with my other cars.
But I stumbled on the Lexus Cth and it seems its a Prius with a Lexus styled body and interior. The Lexus is a more conventional body style and seems to be a little better fit and finish on the interior but at a little less MPG. I tested a 2012 Cth with the F sport package over the weekend nd really liked it.
My on-board computer is consistently telling me 75-99 MPG on trips (usually 10 to 20 mile trips). Obviously that's wrong. Could this be a sign that some system in my car is faulty? Should I get it checked out at the dealer? I don't really care if the computer estimates are off, but am just worried that it could be a signal of something worse.
View 10 RepliesYesterday I was stuck in traffic and the battery eventually went down to 2 bars and the engine came on.
My question is: In stop and go traffic, if I stay in the first half (left part) of the HSI while the engine is on to recharge the battery, is the ICE turning the wheels or just charging the battery?
I brought my 2012 Prius in on St. Patrick's Day for routine scheduled maintenance and was informed about the recall--I hadn't even known yet. I was told it would just take an additional 45 minutes for the software update--no big deal. Except that it was.
They said the computer that was hooked up to my car crashed during the update, and my car computer would no longer recognize the hybrid system. They had no explanation for the crash and said their computer had a full battery, etc. so it didn't make sense, but they would call Toyota to find out way to do and in the meanwhile I would have a rental.
It is April 7 and I still have the rental. They said the part needed, a new computer, is on backorder. They hope it will be in by the end of April but there are no guarantees.
How do I delete the check air filter message from the 2011 Gen 3 computer screen?
View 6 RepliesHow accurate is the calculation from the car's "computer" for the cruising range left?
In my experience from my previous vehicle. When my gas light would come on, I believe it generally meant that I had 2 gallons left in the tank before stranded.
So got this P0A93 code when I was driving on the highway about 65mph, scared to me death when big yellow warning light came on so I returned home and turn the car back on after 30 mins the code and all the warning lights were gone I checked under the hood felt the pump everything was good. I just got done 90k maintance on the car from dealer. So my question is that could be computer error or it could be water pump malfunction? On warranty manual the warranty for inverter with converter covers under 100k so dealer should be able to cover the water pump if it's broken? I driven the car today again at normal temperature and full blast AC on, then again no engine check light on and warning light no message.

View 14 RepliesI have been looking around online for a chrome grille replacement for my 2010 SE Camry. Problem is every site I visit and 90% of the grilles on ebay only sell grilles that fit the LE or XLE model. They all say "Does not fit Hybrid or SE model" however they look the same size in pictures. Are the LE and SE Grilles really not interchangeable for 2010? Here is an example of one I am looking at:

what years and models are interchangeable with the 2010 SE model.
As part of my 60 mile commute everyday to work and back, I would stop by a gas station in a town on my way home that has 30 cent cheaper gas than where I live. The first time I fueled the car there was no problem. Then today even though my gas was at 3/4 full and I stopped anyways to put in 5 dollars.
What happened next was strange, before I stopped to fuel my range was at 448 miles, with the needle exactly on the 3/4 mark, then I put in 5 bucks the needle did not move at all and my range was still at 448 even after I started driving back on the highway again hoping maybe it would reset. The needle then slowly went up but then the range didn't go any higher and was still decreasing as I kept on driving.
The thing different today was I accidentally put in Unleaded PLUS so it mixed with the 3/4 tank of just regular Unleaded gas..but as far as I know that shouldn't affect anything..right?
My 2003 Passat 1.8t starts up but turns off 1-2 secs later. And if it is the fuel pump, where is it on my car?
View 4 RepliesThe computer apparently calculates the fuel economy per trip (or a series of trips if the car is stopped less than 2 hours) but I don't know how to get it to display the fuel economy for the tank full. Normally I'd reset the computer upon refilling but since it calculates per trip it doesn't calculate per tank. Fortunately the fuel gauge seems to be pretty accurate and each mark is approx 1 gal so I can do a quick approximation but I'm used to having the car do the tankful calculation. BTW, I reset on MFA 1, I've never reset on MFA 2 and that doesn't show tankful economy either.
View 3 RepliesI 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.
View 7 Replieswhy sometimes when I start my car it defaults to recirculate and other times fresh air?
I almost always leave it on fresh air but when I start the car it's often on recirculate. AC is off when this happens.
Same thing happens on my wife's Highlander but in no other car have I had this problem.
We want to buy a Premium, but the interior color we want is only available on the Base. We want black on black available on the Base. The only black in the Premium includes the fake wood trimming. If we go with a Base we want to know what we are giving up.
I'm finding it quite difficult to finding a listing of the differences on a feature-by-feature basis between the Base and Premium models. There are general marketing terms but I'm not convinced it represents the complete delta.
While most of the emphasis I've seen on improving fuel economy seems to focus on warming the car up quickly in cool/cold weather, I seem to be experiencing significant mpg drops at the other end of the spectrum.
