Just a thought. I have had this quirky thing for years and am sure they explained why but don't remember.

Does the light that comes on say "Maintenance Required"? If so, that's not the same thing as a Check Engine light. The Maintenance Required light is just an indicator saying that x number of miles have gone by and it's time to change your oil.
There should be a procedure in your owner's manual for how to reset that light. If you can't find it, let me know the model year of your Highlander and I should be able to find the procedure for you.
