The Check Engine light is the only way the engine control can communicate that it needs some help. So that means that any and all faults can light the light - some can be serious, some can be astoundingly minor.
If the engine control determines that a sensor is bad, in many cases it can 'work around' it. The car will still perform anywhere from OK to just as good as new. But the control needs to inform you somehow that it should be take to the shop.
If the car is performing fine, chances are it's a minor sensor problem. It might require a new sensor, or a connector cleaned up. In some cases, the problem will have gone away, and all the dealer will do is clear the fault and send you on your way. Of course, you'll pay for that, but that's true anytime you end up at the dealer. You don't think that coffee in the Service Waiting Room is free, do you?
If the car is running well, the problem is probably minor.
