E 350 V8-6.0L DSL Turbo (2007)
Air Flow Meter/Sensor: Description and Operation
MASS AIR FLOW (MAF) SENSOR
F-Super Duty Mass Air Flow (MAF) Sensor
Mass Air Flow (MAF) Sensor (E-Series)
The MAF sensor provides an analog voltage signal to the PCM proportional to the intake air mass. The MAF sensor uses a hot wire sensing element to
measure the amount of air entering the engine. The hot wire is maintained at 200°C (392°F) above the ambient temperature. Air passing over the hot
wire cools the wire. The current required to maintain the temperature of the hot wire is proportional to the air mass flow. The MAF signal is used to
calculate the EGR flow rate and for concern detection.
