http:ReadManm FFI1M FUEL INJECTION Theory External EMM Sensors Air Temperature Sensor: The air temperature sensor monitors
whose resistance changes with 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.C.W1M, store service code, and turn on the MFI "check engine" lightIf sensor values are below the limits, or
the sensor or its circuit malfunctions, the EMM will store service code, and turn on the MFI"check engine" lightThe engine
will not go into S.L.C.W1M Throttle Position Sensor: The Throttle Position Sensor (TPS) is rotary potentiometerIt's located
on the rear of the throttle bodies by the EMMThe sensor receives voltage signal from the EMMAs the throttle lever is rotated,
the EMM receives return voltage signal through second wireThis signal is relative to the position of the throttleAs the throttle
