I have a 2002 Santa Fe, with a 2.7 V6. I just noticed a check engine light\n(it's the wife's car), and when I checked the code, it is a 0449. I checked\nmy shop manual, and part of the troubleshooting is to check the CCV. I\ncannot find the definition for the CCV. I also found the fuel cap not quite\non tight enough. Will this cause the fault code?\n\nThank you!
