Hello,
In case of such fault code, air filter must be checked and replaced if necessary. Also the intake must be checked for any leaks between the mass airflow sensor and the intake manifold. It is always required to reset the drift adaptation values after the filter replacement or repair of any leaks.
If the intake is in order, the problem can be caused by a faulty mass airflow sensor as well.

Best regards,
Stan
