Check engine light on Sedona

I purchased a 2003 Kia Sedonna with 15000 miles on it 6 weeks ago. Since that time, the "check engine" (emission control systems) light has come on three times. The 1st time the dealer indicated that this was caused by failure to tightly close the gas cap after fueling. The second time, after I assured the dealer that I had been diligent in making certain that the gas cap was tightly closed after each fuel stop, they replaced an emmission control valve and put on a new gas cap. Less than two weeks later, the light has once again come on.

All three times the light has come on I have been traveling in slow traffic, usually at speeds of less than 30 mph. The car has been in Drive with the Overdrive turned off.

Has anyone else experienced this problem? Any insight or advice? Other than this I absolutely love my Sedonna, but am beginning to worry that I have purchased a "Lemon"! Any suggestions?

You may already know this, but... make sure you "click" the gas cap at least three times, don't try to top off the gas, and don't fill the gas with the car running. Other than these suggestions, I don't have any help. Did you get a warranty with your Kia? If so, you'll just have to keep after the dealer. I have also found the 1-800 Customer Service people to be very helpful. Maybe they could steer you toward a more knowledgable service department.

Hope you get it worked out, Kim. I think the Sedona is a great van.

This is extremely common (the light, not necessarily the frequency). How do you know the gas cap is tight? (seriously. just humor me with your answer.)

Why is O/D off?

If you want any assistance other than wild guesses, we need the DTC code or codes that your car is reporting when the light comes on. It starts with a letter and has 4 digits following it. Ex, P0300 would be a generic code for multiple/random cylinder misfire.

If you have an autozone close to you, take the car down there when the light is on and they will scan the computer and give you the codes for free.

A couple of points. I have been "extremely" careful that the gas cap is securely fastened.

The car was not in overdrive because I was traveling at speeds lower than 35 miles per hour. It is my understanding that overdrive should be reserved for highway speeds, thereby obtaining the best gas mileage???

Ok, well you have to make sure you get at least three overtight clicks out of the gas cap before you know it's secure.

O/D on provides the best gas mileage. I would leave the O/D on unless you are driving on lots of hills in the city environment (like San Fran or San Diego) to reduce transmission hunting. Otherwise, it is fine to leave it engaged.
