Fuellnj!ction System External EMM Sensors Air Temperature Sensor: The air temperature sensor monitors the temperature of
temperatureWhen temperature increases, both resistance and voltage also increaseWhen temperature decreases, resistance and
voltage likewise decreaseIf sensor values are above the limits (engine overheat), the EMM will initiate S.L.O.W1M, store
service code, and turn on the MFI "check ;:;; If sensor values are below and turn on the MFI"check sensor or itsligtit":The
engine will not he EMM will store service code, S.w:W' enter lever throttle Crankshaft Position Sensor: The Crankshaft Position
Sensor is magnetic deviceIt generates magnetic field that's induced by the flywheel encoder ribs passing by itThis produces
an AC voltage signal directly related to flywheel RPMCrankshaft TDC is determined by encoder rib spacingThe sensor feeds
the flywheel encoder data to the EMM, which calculates crank position and engine speedThe EMM generates tachometer signal,
and controls fuel injector and ignition operationThe sensor is located on the top of the flywheel housing on the MAG side
