If your check-engine light is, something is wrong. This is a no brainer. But it can be easy to forget what a benefit it is to have your vehicle's electronic control unit (ECU) always scanning input from sensors to make sure the engine and related systems are up to par. Yes, the check-engine light "knows" when something is amiss. The problem is that some people choose to ignore it, saying the cause is just "pollution-related stuff" or, worse, they hear from someone at a shop that "it's not important". When I hear that, I know that particular shop didn't have the expertise to fix the problem. One of the problems of driving with a check-engine light on is that the light doesn't get any brighter, or start blinking to alert you that something very bad is going to happen.
