C. Perform a 45 N (10 lb) pull test on each of
the wires that are associated with the marine
transmission oil temperature sensor.
D. Check the allen head screw on each ECM
connector for the proper torque. Refer to the
diagnostic functional test Troubleshooting,
“Electrical Connectors - Inspect”.
E. Check the harness and wiring for abrasions and
for pinch points from the marine transmission oil
temperature sensor to the ECM.
Expected Result:
All connectors, pins, and sockets are completely
coupled and/or inserted. The harness and wiring are
free of corrosion, of abrasion, and of pinch points.
Results:
•
OK – The connectors and wiring are OK. Proceed

•
Not OK – There is a problem in the connectors
and/or wiring.
Repair: Repair the wiring and/or the connectors.
Replace parts, if necessary. Ensure that all of the
seals are properly in place and ensure that the
