The code reader you used may not be advanced enough to read all codes or to pull stored codes. The CEL may light and then go off (even for problmes much more serious than a loose gas cap). Some codes are still stored. However, some are not. I do not think there is any rhyme or reason to this. Like most things on a Kia, the warning system is unreliable.
DON'T REMEMBER THE SPECIFICS, BUT FOUND 2 KIA SORENTOS WITH MISLABELED WIRING GOING TO THE DLC - HAD TO SWITCH WIRES INTO PINS ON DLC JUST TO MAKE IT COMMUNICATE WITH SCANNER.
