stryker Posted October 27, 2007 Report Share Posted October 27, 2007 I have a check engine on. I was going to check the codes but I don't see a place to check them. Am I missing something or doesn't this year have a test port like my older cars had? Quote Link to comment Share on other sites More sharing options...
slick Posted October 27, 2007 Report Share Posted October 27, 2007 Yes it has the test port. Look down beneath the knee panel. Quote Link to comment Share on other sites More sharing options...
