Question

I have a 2008 Hyundai Sante Fe with engine code P0447. Is this a costly fix?

Answer 1

P0447 Evap emission system vent circuit open

This is not a costly fix but a common problem with the vent control , the inside circuit of the vent tends to open causing a open circuit with the vent control , replace the vent control what is called the CCV (canister closing valve) and make this a hobby in replacing.
