ENGINE MANAGEMENT MODULE (EMM)
SENSORS AND FUNCTIONS
4
If EITHER cylinder head temperature exceeds
248°F (120°C), the EMM
The outboard will not restart, after a temperature
related SHUTDOWN, until the engine temperature
is BELOW 120°C (returns to normal. Refer to
SHUTDOWN MODE on p. 103.
If sensor values are below -15°F (-26.1°C) or
above 331°F (166.5°C), the EMM:
If sensor values are below -4°F (-20°C), the EMM:
If engine does not reach operating temperature on
PORT cylinder head (122°F / 50°C below 2300
RPM) in 10 minutes, the EMM:
If engine does not reach operating temperature on
STARBOARD cylinder head (122°F / 50°C below
2300 RPM) in 10 minutes, the EMM:
Oil Pressure Sensor
The oil pressure sensor monitors oil pressure in
the oil distribution manifold.
If the sensor fails to indicate pressure in the oil
distribution manifold, the EMM:
If outboard has been run for more than 5 hours
with the existance of NO OIL faults (codes 34 &
38), the EMM
IMPORTANT: The outboard will restart for one
minute intervals until problem is resolved and
code is cleared. To clear code use the diagnostic
software propram.
If the sensor circuit fails to indicate within a spe-
cific range or fails, the EMM:
If the sensor circuit indicates below expected
range (<.5 V), the EMM:
If the sensor circuit indicates above expected
range (> 4.5 V), the EMM:
