How do you fix a code po441 on 97 Lexus es300?

A P0441 code on a 1997 Lexus ES300 indicates an issue with the evaporative emission control system, specifically that the system is not purging properly. To fix this, start by checking the gas cap for proper sealing and any cracks. Next, inspect the EVAP hoses for leaks or blockages, and examine the purge valve for functionality. If these components are in good condition, the problem may lie with the EVAP canister or the engine control module, which might require further testing or replacement.
