Hi there:
The DTC P0449 fault code is one of two things 90 percent of the time... either your gas cap is not sealing or your evap vent solenoid is not sealing either.


The code means you have a large evap leak. The evap solenoid is locate near or beside it and has a electrical connector that goes to it. It is either round or square



Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
