2013 Hyundai Tucson P0449 OBD2 Code: Check Engine Light Reappears After Fueling

Model: 2013 Hyundai Tucson Fault Code: P0449 Posted: 2018-01-07 04:35

I own a 2013 Hyundai Tucson and am currently experiencing a persistent check engine light triggered by OBD2 diagnostic code P0449. The issue reoccurs every time I refill the fuel tank, which is causing significant inconvenience. I've tried clearing the code using an OBD2 scanner, but it returns shortly after refueling. This problem appears to be related to the evaporative emission control system, and I'm seeking advice on potential causes and solutions for this recurring fault.
