If you are an immoral son of a bitch, you will be able to pull a fast one by clearing the code and trading in before the light comes on. Just be sure not to complain when you buy a used car and it's a total piece of shit, due to a P.O. with the same moral compass.
Oh ok, I was speaking from experiences on yearly car inspections. I've had many cars which had 02 sensor lights on and i tried clearing the code before the inspection but it would fail every time lol
