How hard is it replace o2 sensor in 2006 Kia?

Do I have to go to a Kia dealer to replace 02 sensor on 2006 Kia?|||Joe's right. You basically unplug then unscrew the old one, and screw the new one in and plug it up. 15 minutes. The light should go off by itself after a few miles, if not have the auto store guy read it and erase it. They have a tool--a split socket--that you can borrow/ rent that will make it easier.|||No, but you should be absolutely certain that the O2 sensor is defective before you go to the trouble and expense to do it. Just because your ECM is displaying a code related to the O2 sensor doesn't necessarily mean that it's defective, have a competent mechanic check it out for you.|||Some, of the members suggested you well.
