Oil Pressure Sensor
The oil pressure sensor monitors oil pressure in
the oil distribution manifold.
If the senso r d oes not de tect pressure f or 1 50
pump cycles (3.3 L mod els), or 75 pump cycle s
(3.4 L models), the EMM:
If o utboard has be en run fo r more th an 5 hou rs
with NO OIL faults (codes 34 & 38), the EMM:
IMPORTANT: The out board will re start for one
minute interva ls until prob lem is re solved a nd
code is cleared. To clear code use t he diagnostic
software program.
If the sensor reads out of the expected range, or
the sensor or circuit fails, the EMM:
If the senso r circuit indicat es below expected
range (<.4 V), the EMM:
If t he se nsor circuit indicates above expected
range (> 4.6 V), the EMM:
Throttle Position Sensor
The throttle position sensor receives a voltage sig-
nal from the EMM. As the th rottle lever is rotated,
the EMM receives a return voltage signal through
a second wire. T his signal increases as the TPS
lever is advanced. A third wire provides a ground
circuit back to the EMM.
If TPS voltage is greater than 0.65 V when the key
is turned to ON, the EMM:
If the outboard is started, the code is saved.
If the key ON voltage is greater than 0.78 V when
the engine is started, speed is limited to idle.
If code 11 is present as both a Active Fault and a
Occurred Fau lt, ref er to Control Cable Inst alla-
tion on p. 19.
If the TPS or TPS circuit fails (less than 0.14 volts
or greater than 4.92 volts), the EMM:
IMPORTANT: When a TPS circuit fault has
been detected, the outboard will no t accelera te
above idle speed. To reset, stop the outboard and
correct the fault.
If the TPS circuit reads below 0.2 volts, the EMM:
If the TPS circuit reads above 4.85 volt s, the
