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 internal
EMM issues.
EMM Temperature Sensor
Monitors the temperature of the fuel injector driver
circuits.
If the EMM temperature exceeds 194°F (90°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. 58.
If EMM temperature is less than -22°F (-30°C) or
the circuit fails, the EMM :
If sensor reads less than -71°F (-57.4°C) or
greater than 313°F (156°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, 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 12.5 V, the EMM :
