CHeck engine light reset - Toyota Nation Forum : Toyota Car and Truck Forums

Hello all, I changed the air filter on my 2010 highlander and forgot to reconnect the MAF sensor connector. My wife tried to start it and now the check engine light is on. Does anyone know how to reset the ECU. I have a maxima and there is series of procedures to reset it. Any help will be greatly appreciated.

pull the battery negative terminal and leave it off for a few mins, does the trick when I trip mine accidently.
also,

That was the ticket for the soft reset, thanks. I'm sure ther is some procedure out there for a hard reset of the ECU... I just haven't found it yet. When I do I'll post it. Thanks again for the help. It appears that we have the identical vehicle's minus the mods. I... err, my wife loves this vehicle.

I wouldn't pull the battery... Just drive the truck a day or 2 and it will go out on its own. Maybe even go out the same day...
