INTERNAL SENSORS
INTERNAL 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.
Internal sensors are NOT serviceable. Repro-
gramming or replacement may be required to
resolve
EMM
related issues.
EMM Temperature Sensor
Monitors the temperature of the fuel injector driver
circuits.
If the
EMM
temperature exceeds 176°F (80°C) or
the circuit fails, the
EMM:
If
EMM
temperature exceeds 212°F (100°C) or
the circuit fails, the
EMM
:
IMPORTANT:
The outboard will not restart until
the engine cools below 212°F (100°C) and the
EMM
temperature returns to normal. Refer to
SHUTDOWN MODE
on p. 100.
If
EMM
temperature is less than -22°F (-30°C) or
the circuit fails, the
EMM
:
If sensor reads less than -67°F (-55°C) or greater
than 311°F (155°C) a sensor circuit fault is
detected and the
EMM
:
55 V Circuit Sensor
Monitors the
EMM
’s 55 V alternator circuit.
If system voltage exceeds 57 volts, the
EMM
:
If system voltage is less than 45 V between 500
and 1000 RPM, or is less than 52 V above 1000
RPM, the
EMM
:
12 V Circuit Sensor
Monitors the
EMM
’s 12 V alternator circuit.
If battery voltage exceeds 15.5 volts, the
EMM
:
If battery voltage is less than 12 V between 500
and 2000 RPM, or is less than 12.5 V above 2000
RPM, the
EMM
