How To Test A RPM Sensor????

[WhoMe08721]

Hey Guys,
How do you test a RPM Sensor on a m998 non turbo 6.5 diesel and if it is bad what would happen??? Also is there any TM manual on this besides TM 9-2320-280-20-2 (4-54)??

Thanks
-Chris

It serves no purpose other then to feed s signal for the STE/ICE...you can unplug it and you will affect nothing.
