As a part of the engine management system, the mass airflow sensor helps adjust to certain changes, like altitude. If your Nissan LEAF is having trouble starting, idling rough or has a sudden quick change in the position of the throttle pedal, this could be a essential sign of a damaged mass airflow sensor.

A damaged sensor can not only affect your miles per gallon, but it can cause serious damage to your catalytic converter and your 2021 Nissan LEAF's spark plugs.
