Sensor Tests; Crankshaft Position Sensor (Cps) Test; Throttle Position Sensor (Tps) Test - BRP EVINRUDE E-TEC 115 HP 2011 Service Manual

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.
Disconnect the crankshaft 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.
Sensor Resistance
560 ± 10% @ 77°F (25°C)
1. CPS 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.
Sensor Resistance (between "A" and "B")
3000 to 7000 @ 77°F (25°C)
Sensor Resistance (between "A" and "C")
4000 to 8000 @ 77°F (25°C)
