EXTERNAL SENSORS

Oil Pressure Sensor
The oil pressure sensor monitors oil pressure in
the oil distribution manifold.
If the sensor does not detect pressure for 150
pump cycles (3.3 L models), or 75 pump cycles
(3.4 L models), the
EMM :
If outboard has been run for more than 5 hours
with 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 program.
If the sensor reads out of the expected range, or
the sensor or circuit fails, the
EMM :
If the sensor circuit indicates below expected
range (<.4 V), the
EMM :
If the sensor 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 throttle lever is rotated,
the EMM receives a return voltage signal through
a second wire. This 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 stored.
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 Hard Fault and a
Stored Fault, refer to
Control Cable Installation
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 not accelerate
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 volts, the
EMM :
