86 N/A S4 MFM AFM meter door readings
Hello,
The FSM says 50 - 500 ohms for the MFM mass airflow meter door opening . . .As more air comes in the door opens up more .
. Between pins E2 and Vs
Open 50 to 500
Closed 50 to 500
86 S4 N/A
What I want to know is if that is a sliding scale where closed is 50 ohms and full open is 500 ohms?. . Or is it gotta be somewhere in that value between open and closed at any point on the sliding scale.
Anybody?
