Lawry13 Posted March 24 Report Share Posted March 24 I have had a P0456 code problem since December. In January, it was smoke tested and determined that the issue was the fuel filler hose. Had that replaced and the code was gone for a month. Check engine light came back on. Repair shop couldn’t find any leaks. They had the software updated and it was good for three weeks. Check Engine Light came back on today. Quote Link to comment Share on other sites More sharing options...
