Consumption Screen Problem

This will happen when the vehicle has been stopped for more than 5 minutes. The mpg doesn't have a reading in those 5 minutes, so you will have a blank bar. Nothing to worry about.

 

It is a feature, not a bug , on the 2006 and later Prius.
We see 100 mpg bar during 5 min stealth driving on the 2004-2005 Prius.

i get this in mu 2005 model prius to!? only then in l/km

 

We've had a single blank five-minute position on a few occasions, but never three; but we haven't needed to stand still for that long. We've also had a 30-minute span of full bars at 99.9, but that was basically coasting downhill in Colorado. I don't see any reason to take the car to a shop.

 

It's completely normal, just as the previous posters have stated.

If you don't have any warning lights on, don't worry. 52 mpg indicated on your MFD is further evidence that all is well. Also note that many dealers' service depts will charge you for an hour of labor in the event that no problem is found (to discourage no-trouble-found complaints).

 

Thats the most common place people see it. The car used only electric to inch ahead, and never started the ICE during that 5 minute period. The computer gets confused by moving some distance but using 0 fuel. Whatever the calculation is its making internally this ends up as 0 mpg instead of infinite mpg. One guess people have made is that its natively calculating L/km, and then converting. 1/(0L/X km) = divide by 0 error.

Nothing to worry about, and does not appear to affect the accuracy of the MFD average MPG number. Its believed that uses the total distance and total gallons, and doesn't care about the 5 minute display.

Had a similar problem today. It occurred while traveling (all EV during this 5 minute stretch... mostly downhill) on expressway while doing 15-20 mph. It was 15 minutes into my commute. Have driven under similar conditions and speed many times in same part of highway without this finding. Interesting quirk. We'll see if it becomes more of an issue.

 

I've had a similar pattern on the consumption screen as well. I was crawling along at about 4mph on a clogged 35mph street with slight ups and downs but generally up. I actually did a double-take when I noticed two consecutive blank columns; the first had two regen leaves and the second had one leaf. I'm still trying to figure out how I got so much regen with so little movement.
