Question about 2002 Kia Rio
The check engine light will come on and stay on when the engine management computer identifies that one or more sensors are providing it with unusual or unexpected readings. The engine management computer will then try to remedy this by using a "safe" default reading instead of the reading supplied by the faulty sensor (this usually allows the vehicle to continue to be driven in "get me home" mode). The check engine light indicates that fault codes have been stored in the EMC memory which can then be interrogated to get an indication of what is causing the fault. A Haynes manual for your particular vehicle will usually tell you a way of reading the fault codes without necessarily passing your vehicle into the hands of a garage for scrutiny. The fault code(s) will then give an indication of which engine parts have failed or are suspect.

One or more of about 500 different things. The vehicle needs to get scanned for a proper diagnosis.

engine light comes on and off, these are indication that there is some
error code stored in your vehicles ECM. The engine module computer
needs to be scanned. These will give the code and as per the error code the
further problem can be detected and confirmed. The engine light
indicator blinks or remains steady on dash when engine computer
noticed any problem with any engine electrically operated components.
