Engine Temperature Sensor; Low Oil Switch - BRP Evinrude E-TEC Series Service Manual

ENGINE MANAGEMENT MODULE (EMM)
EXTERNAL SENSORS

Engine Temperature Sensor

Monitors cylinder head temperature.
If cylinder head temperature exceeds 212° F
(100° C) below 3500 RPM, the EMM:
Activates S.A.F.E.
Stores service code 40
EMM LED 4: ON (Running)
If cylinder head temperature exceeds 194° F
(90° C) above 3500 RPM, the EMM:
Activates S.A.F.E.
Stores service code 43
EMM LED 4: ON (Running)
If cylinder head temperature exceeds 248°F
(120°C), the EMM:
Activates SHUTDOWN
Stores service code 31
EMM LED 4: FLASHING
The outboard will not restart after a temperature
related SHUTDOWN until the engine temperature
returns to normal. Refer to SHUTDOWN MODE
on p. 58.
If sensor values are less than -15°F (-26.1°C) or
greater than 332°F (166.5°C), the EMM:
Stores service code 41
EMM LED 3: OFF (Cranking)
EMM LED 3: ON (Running)
If sensor values are below -4°F (-20°C), the EMM:
Stores service code 42
EMM LED 3: OFF (Cranking)
EMM LED 3: ON (Running)
If cylinder head does not reach operating temper-
ature (104°F / 40°C below 2300 RPM) in 10 min-
utes, the EMM:
Stores service code 58
EMM LED 3: OFF (Cranking)
EMM LED 3: ON (Running)

Low Oil Switch

The low oil switch monitors the oil level in the oil
tank.
If the oil level falls below one-quarter capacity, the
EMM begins counting oil pump pulse cycles.
When it reaches 1000 pulses, the EMM signals:
Engine Monitor LOW OIL display: ON
After LOW OIL is displayed, the EMM counts oil
pump pulse cycles again. When it reaches 6700
pulses, the EMM:
Activates S.A.F.E.
Stores service code 117
EMM LED 4: ON (Running)
Engine Monitor LOW OIL display: ON
To recover from S.A.F.E. mode:
•
Oil level must be above one-quarter
•
The warning resets after three oil pump pulse
cycles when the outboard has been stopped
and restarted.
If outboard has been run for more than 3 hours
with NO OIL faults (codes 34 & 117), the EMM
Activates SHUTDOWN
Stores service code 33
EMM LED 4: FLASHING
Engine Monitor LOW OIL display: FLASHING
If the EMM detects the low oil sensor circuit is
open, the EMM:
Activates S.A.F.E.
Stores service code 120
EMM LED 4: ON (Running)
