Service Manual 115-200 HP 60° V4-V6 E-TEC Engine Managment Module [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. Reprogramming 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. 102.

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:

Barometric Pressure Sensor

Supplies the EMM with barometric pressure reading to compensate for changes in altitude and air density.

If the BP sensor reads less than 13 KPa or greater than 119.0 KPa, or the sensor or circuit fails, the EMM:

If the BP sensor reads less than 70 KPa, the EMM:

If the BP sensor reads greater than 105 KPa, the EMM:

Exhaust Pressure Sensor

The exhaust pressure sensor monitors exhaust pressure during all running conditions to compensate for engine loads.

If the sensor reads less than -85 in. water, or greater than 85 in water, or the sensor or circuit fails, the EMM:

If exhaust pressure is less than 40 in. water, the EMM:

If exhaust pressure is greater than 80 in. water, the EMM:

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 circuits. 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 temperature 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 PORT cylinder head temperature is greater than 212°F (100°C) below 2000 RPM, or greater than 194°F (90°C) above 2000 RPM, the EMM:

If STBD cylinder head temperature is greater than 212°F (100°C) below 2000 RPM, or greater than 194°F (90°C) above 2000 RPM, the EMM:
