Code P0446
 

We have been dealing with issue almost since we purchased our 2004 Hyundai Sonata. The first time the 'check engine' light came on, we had 15,000 miles on the car. The CANISTER CLOSE VALVE was replaced. We have had to deal with this issue at least once a year since we purchased the car. Has anyone else had this much problem with this part? Is there a solution?
