I have a 2006 ford explorer I have replaced the canister vent solenoid before and I thought I had to replace it a second time I had the vehicle smoke tested and the mechanic told me the vent solenoid was bad again however after replacing it the code remains even if I clear it manually the code is a p0446 and I don't know what else I can do. Any help?

 

Has the gas cap been checked?
