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
EMM:
EXTERNAL SENSORS
Sensor inputs and internal
EMM
controllers are
used to control outboard operation. Use
Evinrude
Diagnostics
software to troubleshoot the sensors.
Refer to the
EMM Service Code Chart
at the
back of this manual for a complete list of all
engine fault codes.
The
EMM
provides a 5 V DC signal for sensor cir-
cuits. It monitors all sensor voltage inputs and
compares them to predetermined acceptable
ranges. Inputs that fall outside of the acceptable
range create service codes.
Air Temperature Sensor
The air temperature sensor monitors the air tem-
perature at the throttle body.
If the AT sensor voltage is out of the expected
range, or the sensor or circuit fails, the
EMM:
Engine Temperature Sensor
Monitors cylinder head temperature.
If cylinder head temperature exceeds 212° F
(100° C) below 2000 RPM for 3 seconds, the
EMM
:
If cylinder head temperature exceeds 185°F
(85°C) above 2000 RPM for 60 seconds, the
EMM
