SENSOR TESTS
All sensor circuits are dependent on wiring and
connections,
EMM
supplied current (5 V), and
sensor resistance. The supplied current flows
through the wiring circuit and sensor before
returning to the
EMM
.
IMPORTANT:
Use
Evinrude Diagnostics
soft-
ware to monitor sensor circuit voltages or values.
Crankshaft Position Sensor (CPS)
Test
Use the
Evinrude Diagnostics
software CPS Sync
and engine RPM displays to confirm a valid CPS
signal while the outboard is cranking or running.
An RPM display higher than zero indicates a CPS
signal to the
EMM
.
Remove the electrical connector from the crank-
shaft position sensor.
Use a digital multimeter to measure sensor resis-
tance between the yellow and white wires. The
complete circuit can be tested by measuring
between pins 6 and 7 of the
EMM
J1-A connector.
.
The CPS is mounted to throttle body housing and
requires no adjustment. Air gap or clearance to
flywheel is fixed at approximately 0.073 in.
(1.85 mm). The acceptable clearance is 0.036 to
0.110 in. (1 to 2.8 mm).
Throttle Position Sensor (TPS) Test
Use
Evinrude Diagnostics
software to monitor
TPS voltage while the outboard is running. Volt-
age should change evenly as sensor lever is
moved.
Remove the electrical connector from the throttle
position sensor.
Use a digital multimeter to measure sensor resis-
tance.
