of the EMM Barometric Pressure (BP) Sensor: The BP sensor is silicon pressure sensor having diaphragm sealed air passage
that generates an AC voltage signalIt senses ambient air pressure through screened port that's open to atmosphereThe BP signal
enables the EMM to compensate for pressure changes caused by altitude so it can adjust fuel flow accordinglyIf sensed values
are out of limits, or the sensor or circuit fails, the EMM will turn on the MFI "check engine" light, and store service codeEMM
Temperature Sensor: Monitors fuel injector driver circuit temperature to prevent it from exceeding design limitsOne or more
fuel injectors could malfunction should this occurIf sensor values are out of limits, or the sensor or circuit fails, the
EMM will turn on the MFI "check engine" light, and store service codeThe EMM will also initiate S.L.O.W1M, only if excessive
