Prius (2010-12) Fuel :: Is Computer Programmed For 0% Ethanol Or E10
I'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 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.

Prius (2010-12) :: Got Code P0A93 - Computer Error / Water Pump Malfunction?
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 5 RepliesFord 6.0L Power Stroke Diesel :: 2003 F250 - How To Reset Average MPG Calculator
I have a 2003 F250 4X4 PSD. How do I reset the "Average MPG" calculator? I asked because I have doubts that it is functioning properly.
Example:
Zero load, high-way driving.... the display shows 14.4mpg.
Zero load, in-town driving... the display shows 14.mpg.
1,000 lbs in the truck, pulling 4,000 lbs on the high-way for 600 miles (each way)..... the display shows 14.2mpg.
And since I've returned from the trip mentioned above with the 5K of load, it has not changed from displaying 14.2mpg.... even though I am back to high-way driving with zero load... been through 6 -8 tanks of fuel.
My expectation is that when I am traveling without a load on the high-way that it should get the best MPG. Subsequently, when I am pulling a load, utilizing the "Tow" function (without engaging O/D), that it would get worse MPG. However, it appears there is virtually no difference registered / displayed in MPG regardless of how I drive or what I tow.
Lexus RX 2010-15 :: 2012 RX350 - Computer DTE Calculation Doesn't Match MPG?
Just got a (second) 2012 RX350. 13,000 miles. The Distance to Empty is confusing me. Doesn't come close to matching the tank size times either the mpg since last fill-up, or the overall average mpg. Overall mpg is 17.x. mpg since last fill-up varies from 17-21. But when I fill the tank, the DTE says maybe 260. With a 20gal tank the DTE after a fill-up should be in the 340-350 range.
This isn't happening on our other 2012 RX350 with about the same number of miles.
The needle gas gauge appears to be right, based on where the needle is before a fill-up and the number of gallons purchased.
Prius (Gen 2) Fuel :: Accuracy Of Gas Mileage As Reported By Computer?
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?

I've had this car for a couple of years now and I think this week is the first time I didn't 'fill up' when I got gas. So now the trip computer is all confused on miles to empty vs the almost half tank I have on the fuel gauge. I've tried resetting the trip & holding the button to reset when miles to empty is displayed. I'm a little nervous with the miles to empty in the single digits now.
