Air Flow Meter/Sensor: Description and Operation
Without Speed Density Update
The Mass Air Flow (MAF) sensor produces a frequency output which is directly proportional to the air entering the engine. The output will vary from
approximately 32 Hertz at idle to 150 Hertz during wide open throttle. If the sensor fails at a low frequency, a code 34 will be set and stored. A code 44
or 45 may also be caused by a faulty MAF sensor.
