Just bought a 2015 edge titanium awd with 114k on it. Was going good for a week or so until the check engine light came on but with no noticeable problems. Ran the scanner and got P1450 and found out about only replacing the purge valve instead of the whole harness, hoping to save $125 on the fix. Took off the old purge valve and tested it anyways and it seemed fine but I installed the new one from amazon along with a new hose. Code P1450 stayed but then it added code P0443 along with it. Do I try replacing the vapor canister solenoid, or the vapor canister with a new solenoid, or just bite the bullet and get the new purge valve vapor harness? All of the above? If I need a new vapor canister, do you know where I can find one for less than $100? Thanks
