5 V Circuit Sensor
Monitors the EMM ’s 5 V sensor circuit.
If sensor voltage is less than 4.75 volts, the EMM :
Barometric Pressure Sensor
Supplies the EMM with barometric pressure read-
ing to compensate for changes in altitude and air
density.
If the BP sensor reads less than 13 KPa or greater
than 119.0 KPa, or the sensor or circuit fails, the
EMM:
If the BP sensor reads less than 70 KPa, the
EMM:
If the BP sensor reads greater than 105 KPa, the
EMM:
Exhaust Pressure Sensor
The exhaust pressure sensor monitors exhaust
pressure during all running conditions to compen-
sate for engine loads.
If the sensor reads less than –85 in. water, or
greater than 85 in. water, or the sensor or circuit
fails, the
EMM:
If exhaust pressure is less than 40 in. water, the
EMM:
If exhaust pressure is greater than 80 in. water,
the
