You are in the Toyota Sienna
What is this discussion about?
Toyota Sienna, Van
#231 of 250 2007 Limited fwd
Dec 05, 2008 (9:38 pm)
We have 76,000 on our van. I have run two 20,000 tests. Each has averaged 24.x
We live in South Dakota during the summer so do more highway than city driving. We drive the posted speed limit, freeway here is 75, four lanes are 70 and two lanes 65, gravel 55, city 25...30
We live in Arizona during the winter and do mostly city driving at 45, two lane 55...60, freeway 70
As much as possible we avoid ethanol blend gas because we have found a 2...3 mpg decrease in milage over several successive tanks.
Hope this is useful information

Sorry it took me a while to answer you,,,,,,,,,, it hasn't really opened up,,,,,, I already have 23k miles on it and I'm still getting between 14 to 16 mpg's per full tank. I always complain at the dealership every time we bring her in for service but now they just say that those numbers are what they have been getting with the bigger engine on the sienna AWD's,,,,,,, I should have just convinced my wife to get an SUV

Wow, awesome mileage on the open road. We can't get above 15. Around town, our numbers are like yours -- 12-13 and sometimes 14 if we have been on the freeway a lot. Average mileage is at 13.7 with 7000 miles on our van ('08 limited AWD). The dealer did not care and said mileage varies and you can't rely on the posted numbers which are done on a machine for something like 65 mph highway and 35 city without the starts and stops. DTE still reads 250 for every fill up and it's pretty pathetic. Our catalytic converter is bad, and needs to be replaced, although the dealer said that probably would not affect mileage.

Thanks for your reply. At 7000 miles, I'd be happy with 14-16 overall. We are getting 12-14 depending upon driving conditions. 14.5-15 is the most we can get on long drives. SUV next time - might as well have the V8 for what we are getting. I wish it were something like the brakes riding - could not get that lucky. Good luck and know that misery loves company
#235 of 250 Need help on gas mileage!!!
Jan 06, 2009 (2:15 pm)
Recently my 2002 Sienna reached 80,000 miles, right before that, my engine light and 2 others came on. The problem was the CAT (catalitic converter). Luckily the converter was in the warranty (80,00 miles) and the dealer replaced one of them (near the engine block). I asked how do they know which one would be bad and they said they did not know, but most likely would be the one by the engine, for there are 3 CAT's in this van.
Prior to all above described, I was getting about 22mpg, after that, 17mpg and also with a "pop" noise every-now-and-then on the gas pedal. My mechanic did not have an answer for this problem.
Did anyone run into something like this?
Thanks for any info

I just bought a used 2007 Sienna. (I utilized some of the issues discussed in this forum)
My question is "How do I reset the trip computer?"
I'm not talking about the one on the dash, I mean the one on the overhead console that calculates avg mpg.
Thanks in advance.

Hi to reset the overhead computer: While parked, 1. select the avg mpg display. 2. Hold down both outside buttons at the same time until the display goes blank...(about 3seconds) . Trip computer should be reset......let me know if this doesnt work...I am doing this from memory away from my car thanks good luck
#239 of 250 06 Sienna Cumulative MPG Meter Error (?)
Feb 04, 2009 (9:17 am)
Just bought a 06 used Sienna, I have had it for a week. I was looking forward to the cumulative MPG meter- which seems to be stuck at 17.7 mpg. This cannot be right, as most of my miles are highway.
Is the meter broken? Is is 17.7 mpg over the whole life of the van (32 K miles)?
I reset both odometers (trip A & B) and just refueled. No change.
Is there are reset button or am I missing something...

You can reset it - first put it in Drive. Then go to the avg mpg readout. Next, hold to two outer-most buttons on the trip computer.
It will flash, then read 0.0.
I do that each time I fill up, basically.
