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:
Engine Temperature Sensor
Monitors cylinder head temperature.
If cylinder head temperature exceeds 212° F
(100° C) below 2000 RPM, the
EMM :
If cylinder head temperature exceeds 185°F
(85°C) above 2000 RPM for 60 seconds, the
EMM :
If cylinder head temperature exceeds 194°F
(90°C) above 2000 RPM for 3 seconds, the
EMM :
If cylinder head temperature exceeds 248°F
(120°C) for 3 seconds, the
EMM:
The outboard will not restart until the engine tem-
perature returns to normal. Refer to
SHUTDOWN
MODE on p. 63.
If sensor values are less than -13°F (-25°C), or
greater than 329°F (165°C), the
EMM:
If sensor values are below -4°F (-20°C), the EMM:
If cylinder head does not reach operating temper-
ature (122°F / 50°C below 1000 RPM) in 10 min-
utes, the
