Hello all, newbie here. Last week I purchased a 2016 Rav 4 LE in Denver, Colorado and drove it to my home in NH. Is there anything I need to do as far as corrections for the difference in altitude 6000 feet in Denver to 300 feet in NH? It seems to run fine. The other issue is a check engine lite, took it to a local general shop, codes said evap, had the canister assy replaced (pretty pricey) worked for a day and the darned light is on again. Going to return it to the shop for a re-look Monday. Any suggestions as to either question? Thanks a lot in advance...

 

No adjustments needed for altitude, the computer does it all. As far as your engine light who knows without a reader, let the shop do their thing.

 

Interesting topic!
My 22RE does OK in low altitude but going up same grade slopes in high altitude, I could only do around 50 in 3rd gear or 55 in 4th. I suspect it must be the thinner air - less oxygen in a given volume of air.
I am not aware of any sensor the ECU uses to sense altitude.

 

Thank you for the info, wicked smart 'puters right? It is in the shop today for evaluation on the engine lite, have a great day!!!!

 

I would imagine air to fuel/Timing is taken care of which I guess would be altitude in a dumb way, I doubt computers have an altimeter. But I have never had an issue in my 22re, but in my carbed el Camino that’s a whole other pinging story at 8000ft
