What happens if your MAF sensor is bad?
The mass airflow sensor (commonly abbreviated to MAF) is one of the most important engine management sensors. A bad mass airflow sensor can leave your Nissan Patrol’s engine running rough, or even inoperable. A MAF sensor measures the density of the air entering the intake manifold. It passes this information onto your Patrol’s ECU.
