FICHT- FUEL INJECTION Theory External EMM Sensors Air Temperature Sensor: The air temperature sensor monitors the temperature
with temperatureWhen temperature increases, both resistance and voltage also increaseWhen temperature decreases, resistance
and VOltage likewise decreaseThe sensor receives VOltage signal from the EMM, and another wire provides ground circuit back
to the EMMThe EMM uses this signal to adjust the airfuel ratio in accordance with changes in engine water temperatureIf sensor
values are above the limits (engine overheat), the EMM will initiate S.L.O.WIN, store service code, and turn on the MFI "check
engine" light If sensor values are below the limits, or the sensor or its circuit malfunctions, the EMM will store service
code, and turn on the "check engine" lightThe engine will not go into S.L.O.wIN 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
