Maybe its the scheduled maintence item: time to change the oxygen sensor(s). Often, this code is stored in non-volatile memory and will not erase by disconnecting the battery. It requires a special tool to reset the code, and the dealer will not reset this code until he has changed the oxygen sensor(s).

I am not familar with Toyotas, but on some of my cars, the light that signaled it was time to change the oxygen senso((s) was a separate lamp and read, "maintence required". So maybe, a trouble code has been set. Who knows? The best way to find out is to read the code, or have the code read by a repair shop with the proper tools.
My advice: Quit guesssing and have the code read. Remember, reading the code is only the first step in diagnosing a problem.
