Intrigue V6-3.8L VIN K (1998)
Air Flow Meter/Sensor: Description and Operation
Mass Air Flow Sensor
The Mass Air Flow (MAF) sensor measures the amount of air which passes through the throttle body. The 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.
The scan tool displays the MAF value in grams per second (g/s). At idle, MAF should read between 4 gm/s -7 gm/s on a fully warmed up engine. Values
should change rather quickly on acceleration, but values should remain fairly stable at any given RPM. A MAF sensor malfunction or MAF signal circuit
problem should set DTC P0101, DTC P0102, or DTC P0103.
