Common check engine problems for the Subaru Liberty with the EJ22 engine often include issues with the mass airflow sensor, oxygen sensors, or vacuum leaks. Additionally, problems with the catalytic converter or ignition components, such as spark plugs and coils, can trigger the check engine light. Routine diagnostics using an OBD-II scanner can help identify specific trouble codes related to these issues. Regular maintenance is key to preventing and addressing such problems.
