oxygen sensor / mass air flow sensor on 1997 Mercedes-Benz E320

are these the same? I was told I needed a new mass air flow sensor after my check engine light came on.

Mass airflow sensors and oxygen sensors are not the same component. A failed mass airflow sensor can definitely cause a check engine light, and they are not an uncommon problem on most cars.
