Defective vent valves, fuel tank filler necks, EVAP hoses, carbon canisters, gaskets, and fuel tanks are all potential causes of code P0449. Since a code P0449 relates to a leak in the evaporation system, anywhere that fumes could be escaping is a potential cause.
Can I drive with a P0449 code?
What Does Code P0449 Mean? Issue Severity: LOW– Continued driving for a short period of time is okay. Repair Urgency: Get this code fixed withing the next month to prevent issues related to the emissions system including failed inspections.
Where is the EVAP vent solenoid located?
Note: The EVAP vent solenoid is typically located near the rear fuel cell. The solenoid is usually removed in order to fix the problem; however, in some cases, the solenoid is attached to a vent tube that is recommended be replaced at the same time.
What does po449 mean?
Code P0449 indicates that the evaporative control (EVAP) system vent valve solenoid is malfunctioning. This can be caused by either too little or too much electrical resistance or a mechanical problem with the vent valve itself. Need help with diagnosing your trouble code?

Can EVAP solenoid misfire?
Can Evap Leak Cause Engine Misfire? EVAP leaks can cause misfires because they are tied to the fuel-air mixture of a vehicle.
How do you find a large EVAP leak?
Typically to find a leak, a mechanic would need to test the entire EVAP system using an advanced scan tool and the testing equipment known as a ‘smoke machine’. The “smoke machine” (see the photo) pushes the “smoke” through the system, so that any leak can be visually detected.
What is a vent solenoid?
The Vent Solenoid is a normally open valve that is commanded closed to seal the EVAP system and stop air flow into the charcoal canister. The Purge Solenoid is normally closed but is opened by the PCM to allow manifold vacuum in the EVAP system — thus drawing fuel vapours from the EVAP system.
