ENGINE MANAGEMENT MODULE (EMM)

EXTERNAL SENSORS

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:
Stores service code 47, 48, or 49
EMM LED 3: OFF (Cranking)
EMM LED 3: ON (Running)

Engine Temperature Sensor

Monitors cylinder head temperature.
If cylinder head temperature exceeds 230° F
(110° C) below 3000 RPM, the EMM:
Activates S.A.F.E.
Stores service code 40 (port sensor)
Stores service code 70 (stbd sensor)
EMM LED 4: ON (Running)
Engine Monitor TEMP display: ON
If cylinder head temperature exceeds 194° F
(90° C) above 3000 RPM, the EMM:
Activates S.A.F.E.
Stores service code 43 (port sensor)
Stores service code 69 (stbd sensor)
EMM LED 4: ON (Running)
Engine Monitor TEMP display: ON
56
If cylinder head temperature exceeds 248°F
(120°C) for 3 seconds, the EMM:
Activates SHUTDOWN
Stores service code 31
EMM LED 4: FLASHING
Engine Monitor TEMP display: FLASHING
The outboard will not restart until the engine tem-
perature returns to normal. Refer to SHUTDOWN
MODE on p. 61.
If sensor values are less than -13°F (-25°C), or
greater than 329°F (165°C), the EMM:
Stores service code 41 (port sensor)
Stores service code 67 (stbd sensor)
EMM LED 3: OFF (Cranking)
EMM LED 3: ON (Running)
If sensor values are below -4°F (-20°C), the EMM:
Stores service code 42 (port sensor)
Stores service code 68 (stbd sensor)
EMM LED 3: OFF (Cranking)
EMM LED 3: ON (Running)
If cylinder head does not reach operating temper-
ature (122°F / 50°C below 1000 RPM) in 10 min-
utes, the EMM:
Stores service code 58 (port sensor)
Stores service code 59 (stbd sensor)
EMM LED 3: OFF (Cranking)
EMM LED 3: ON (Running)
