Many of those boxes have timer function, even when they are not able to record the program by themselves, but for this exact reason, they'll turn on to programmed channel.

Your car is emitting O2? What make is it! We may have saved the planet!
His car is running lean and that's why there's too much O2 in exhaust, too much oxygen for amount of gasoline injected. So the engine isn't running as efficiently as it could and is probably producing too much NOx so it would fail the emissions test.
And if it's just a failed O2 (Lambda) sensor then it will be probably running rich, computer injects excessive amounts of fuel to the engine just because it thinks that we're running lean. And yet again, fail in emissions.
So no, planet isn't saved.
