Well it means that there is a sensor reading that is out of range. Each sensor has a specific electrical value range that it constantly puts out, when it goes outside this range the check enigne light comes on. The reason that you might not notice any problems is because the computer is compensating using all the readings from the other sensors, and susbstsituting the erractic value from the sensor with one that it sees appropriate, thus causing the car to run next to normal. Fuel economy might suffer.
Have it checked at a shop, they will use a scan tool and retrieve what is causing the problem and be able to see what needs to be replaced. Take it ASAP, it might not seem like anything is wrong but its best to make sure. If the light is flashing instead of solid then it is super urgent.
