Mass Air Flow Sensor: Description and Operation
DESCRIPTION
The Mass Air Flow (MAF) sensor measures the amount of air which passes through it. The Powertrain Control Module (PCM) uses this
information to determine the operating condition of the engine, to control fuel delivery. A large quantity of air indicates acceleration, while a small
quantity indicates deceleration or idle.
