Crankshaft Position Sensor; Neutral Switch (V4 Models) - BRP EVINRUDE E-TEC 115 HP 2011 Service Manual

ENGINE MANAGEMENT MODULE (EMM)
EXTERNAL SENSORS

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:
•
Below 2000 RPM: 5 occurrences
•
Above 2000 RPM: 1 occurrences
the EMM:
Stores service code 16
EMM LED 2: OFF (Cranking)
EMM LED 3: ON (Running)
Approximate air gap between CPS and flywheel
encoder ribs is 0.073 (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 (V4 Models)

The powerhead mounted neutral switch controls a
ground signal from the EMM to indicate shift link-
age position when a tiller kit has been installed.
This allows the EMM to provide start in gear pro-
tection. Fuel and ignition functions are turned off
on tiller models 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:
Stores service code 19
EMM LED 3: OFF (Cranking)
Engine Monitor CHECK ENGINE display: ON
The Monitor screen of the diagnostics software
displays switch position, NEUTRAL or IN GEAR.
Make sure switch is operating properly.
