Circuit Sensor; Barometric Pressure Sensor; Exhaust Pressure Sensor - BRP EVINRUDE E-TEC 115 HP 2011 Service Manual

5 V Circuit Sensor
Monitors the EMM's 5 V sensor circuit.
If sensor voltage is less than 4.75 volts, the EMM:
Stores service code 78
EMM LED 3: OFF (Cranking)
EMM LED 3: ON (Running)

Barometric Pressure Sensor

Supplies the EMM with barometric pressure read-
ing 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:
Stores service code 44
If the BP sensor reads less than 70 KPa, the
EMM:
Stores service code 45
If the BP sensor reads greater than 105 KPa, the
EMM:
Stores service code 46
ENGINE MANAGEMENT MODULE (EMM)

Exhaust Pressure Sensor

The exhaust pressure sensor monitors exhaust
pressure during all running conditions to compen-
sate 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:
Stores service code 87
EMM LED 3: OFF (Cranking)
EMM LED 3: ON (Running)
If exhaust pressure is less than 40 in. water, the
EMM:
Stores service code 88
EMM LED 3: OFF (Cranking)
EMM LED 3: ON (Running)
If exhaust pressure is greater than 80 in. water,
the EMM:
Stores service code 89
EMM LED 3: OFF (Cranking)
EMM LED 3: ON (Running)
