Here is the description of the code: P0443 Evaporative Emission Control System Purge Control Valve Circuit Malfunction
Sounds like there is a problem with the evaporative system, and possibly the purge valve. To be sure, it will need to be diagnosed by a technician. I suggest taking it to a shop that performs smog test and repairs, they will be fully equipped to diagnose and fix this problem.

I had the same problem with my car. I went to the dealer and purchase a new gas cap. A leaky or missing fuel filler cap could be the solution. Good luck.

just do a fuel clean and check if the gas cap is defect and change it
