Chevy Silverado: Bad MAF Sensor → Symptoms Causes ...

+

Aug 06, 2019· 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 Chevy Silverado’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 Silverado’s ECU.

Mass Airflow Sensor Description and Operation

+

The mass air flow (MAF) sensor is an air flow meter that measures the amount of air entering the engine. The powertrain control module (PCM) uses the MAF sensor signal in order to provide the correct fuel delivery for a wide range of engine speeds and loads. A small quantity of air entering the engine indicates deceleration or idle.
