Airflow Sensor: Operation
- The airflow sensor is incorporated within the air cleaner. It functions to convert the amount of engine air intake to pulse signals of a frequency proportional to the amount of engine air intake, and to input those signals to the engine control unit. Then engine control unit then, based upon those signals, calculates the amount of fuel injection, etc.
- The power for the airflow sensor is supplied from the control relay to the airflow sensor, and is grounded at the engine control unit. The airflow sensor, by intermitting the flow of the 5-volt signal applied from the engine control unit, produces pulse signals. See Fig 1
