  • The check engine light is only for emissions related problems which I would not think your problem falls under.
  • Brand new 2012 HiHy - gets 13.5 l / 100 km instead of the advertised 7.3. Dealer was no help.

    Followed newski3 procedure to reset the ISC. The system is much improved.

    Thank you very much.

    Looking at the 2007 Highlander Hybrid Review on Edmunds, your mileage looks really good relative to the EPA estimated mileage for the vehicle. Given the price of gas, we ALL want all the mileage performance we can get.
    I suppose using some of the techniques hypermilers use might get you a bit more. You can read about it in this Edmunds article:

    2016 Highlander Hybrid Platinum ... I drove Sacramento California to Reno Nevada (120 miles), around Reno for half a day, then back to Sacramento. Mileage up to Reno 30.4 mpg, around Reno 27.3, and trip back to Sacramento 38.7 mpg. The average for the tank was 28.7

    Hello out there! Can't seem to find easy/free access to service bulletins. Many posts here about "Idle Speed Control" or "Idle Speed Learning" resets. Question: Do either of these procedure apply to the 2007 HH and if so, where can I get references for the procedure/s?

    Well, if you Google "2007 Toyota Highlander Hybrid TSB" you'll come across a list of 15 TSBs from April 2007 to October 2013, none of which are about Idle Speed. If I search for THH TSB Idle Speed, I see there was one for the 2008 HH

  • Hello, out there! Anyone still using this forum? Don't see any posts in this section after 2017. I find it hard to believe that everyone out there is completely satisfied with their HH mileage and no one needs any more advice on this. I sure need some!
