If TPS voltage is greater than 0.78 volts when the
key is turned to ON, or the recoil starter is pulled,
the
EMM
:
If the outboard starts, the code is saved.
If code 11 is present as both a Active Fault and a
Occurred Fault, refer to
on p. 21. For tiller models, refer to
If the TPS or TPS circuit fails (below 0.14 volts or
above 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
:
Crankshaft Position Sensor
Ribs spaced on the flywheel mark crankshaft posi-
tion. As the ribs pass the magnetic field of the
CPS, an AC voltage signal is generated. The
EMM
uses this signal to identify crankshaft posi-
tion and speed, generate a tachometer signal, and
control fuel and ignition timing.
If the sensor is damaged or the signal is intermit-
tent (10 occurrences), the
EMM
:
Approximate air gap between CPS and flywheel
encoder ribs is 0.073 inch (1.85 mm).
Use the
Evinrude Diagnostics
software
Monitor
screen to check CPS operation. The software
should show an RPM reading while the outboard
is cranking. If the CPS or its circuit fails, no RPM
reading will appear and the outboard cannot run.
Neutral Switch
The powerhead mounted neutral switch controls a
ground signal from the
EMM
to indicate shift link-
age position. This allows the
EMM
to control idle
speed variations and start in gear protection. Fuel
and ignition functions are turned off if the neutral
switch is not closed.
If the starter is cranked while the outboard is in
gear, or if the switch fails, the
EMM
:
The
Monitor
screen of the diagnostics software
displays switch position, NEUTRAL or IN GEAR.
Make sure switch is operating properly.
