INTERNAL SENSORS
INTERNAL SENSORS
Sensor inp uts and inte rnal EMM contro llers are
used to control outboard operation. Use Evinrude
Diagnostics software to troubleshoot the sensors.
Refer to t he EMM Servic e Code Chart at the
back of this manual for a comp lete list of all
engine fault codes.
Internal sensors are NOT serviceable. Re pro-
gramming or replacement ma y 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 temp erature excee ds 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 temperatu re returns to normal. Re fer to
SHUTDOWN MODE on p. 63.
If EMM temperature is less tha n -22°F (-30°C) or
the circuit fails, the EMM:
If sensor reads less than -67°F (-55°C) or greater
than 31 1°F (155°C) a senso r circu it 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 volt age is less than 45 V between 5 00
and 1000 RPM, or is le ss than 5 2 V above 10 00
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 volt age is less tha n 12 V below 20 00
RPM, or is less than 12.5 V above 2000 RPM, the
EMM:
