Engine Sensors; Alarms; Water Temperature - ILMORE 5.3L GDI Owner's Manual

ENGINE SENSORS

The engine is equipped with many sensors. These sensors provide
performance information such as engine speed, engine coolant
temperature, engine oil pressure, and much more.
The engine management system uses these sensor to alert the
operator of any irregularities during engine operation. Most sensors trip
audible or visual alarms on gauges or other dash displays. DO NOT
ignore alarms. Owners are urged to take the boat to an authorized Ilmor
service center for analysis if or when a malfunction is suspected after
sensing an alarm.
NOTICE: Always pay attention to the audio and visual alarms. Boats
are equipped with a variety of audible and visual alarms that alert
operators to potential performance issues. No alarm, whether it
sounds an alert or provides information on the gauges, should ever
be ignored. The powertrain sensors are often the earliest indication
of problems, and if ignored, may result in serious damage to the
equipment that is not covered under warranty.

ALARMS

Read the accompanying boat owner's manual for important information
regarding alarms and gauges.
The Ilmor engine alarm system displays a visual alarm whenever any
monitored engine parameter is not in operating range. If an alarm is
present, throttle back immediately, if safe, and identify which gauge
is out of range. Alarm display varies between boat models. Most boat
models use a centrally mounted gauge with specific engine response.
In boats equipped with more than one engine, there will be separate
alarms for each engine. Refer to the boat manufacturer's operator
manual for more information.
The alarm activation will display if the following conditions occur:
• Water temperature (Engine Coolant Temperature Higher than
Expected)
• TPS Error (Engine Throttle Not Responding)
• FPP Error (Foot Pedal Signal Error)
• Fuel Injector Error (Injector Circuit Shorted)
• Low oil pressure
• One-Drive
• One-Drive
• Exhaust Raw Water Temperature Sensor (GDI-S models only)
NOTE: The engine monitor alarm will display when ignition is turned
to running position. The alarm will shut off momentarily. After the engine
is started the alarm will not alert again. If the alarm sounds or displays
at any other time, or for any other reason, contact an authorized Ilmor
service center before restarting the engine.

Water Temperature

Alarm appears if the engine coolant exceeds preprogrammed limits.
If this occurs, return the engine or engines to idle for cool-down. If the
temperature is still increasing, shut engine off immediately, if safe. Confirm
that the seacock is open and that the sea strainer is clear. If neither of
these is the cause, take the boat to an authorized Ilmor service center.
