Intermittent Engine Shutdown - Perkins 1104E Series Troubleshooting Manual

RENR2696-01
Coolant Temperature
Refer to Troubleshooting, "Coolant Temperature Is
Too High".
Check for High Intake Air Restriction
and/or High Altitude
When intake air pressure is low, the turbocharger
(if equipped) works harder in order to achieve the
desired intake manifold pressure. This increases
intake air temperature.
Measure the intake manifold pressure while the
engine is operating under load. For specific data,
refer to the Technical Marketing Information for the
engine.
Intake Air Restriction
Check for plugged air filters. Check for obstructions
to the air intake.
Replace the air filters and/or remove the obstruction
from the air intake.
High Altitude
Make sure that the settings for the engine are correct
for the altitude.
Check the Intake Manifold Air
Temperature Sensor and/or the
Circuit
Allow the intake manifold air temperature sensor
to cool and remove the sensor. Check the reading
for the intake air temperature. If the sensor is
OK, the reading and the ambient temperature are
approximately equal.
If the reading is not correct, replace the sensor with
a sensor that is known to be good. Verify that the
problem is solved.
Check for Sufficient Coolant Flow
Through the Aftercooler (if equipped)
Check the intake temperature of the coolant for the
aftercooler. Compare the reading to the regulated
temperature. If the temperature is OK, check the
outlet temperature of the coolant. A high temperature
differential indicates an insufficient flow rate.
If there is a high differential between the intake
temperature and the outlet temperature of the coolant
for the aftercooler, perform the following procedures:
•
Check the coolant circuit of the aftercooler for
obstructions.
•
Check the pump for proper operation.
•
Make repairs, if necessary.
Check for Sufficient Flow of Air Through
the Aftercooler (if equipped)
Determine the pressure differential of the intake air
across the aftercooler. For specific data, refer to the
Technical Marketing Information for the engine.
If the pressure differential of the air across the
aftercooler does not match the specifications, clean
the aftercooler.

Intermittent Engine Shutdown

Note: Use this procedure only if the engine shuts
down completely and the engine must be restarted.
Probable Causes
•
Refer to the logged codes.
•
Fuel supply
•
Engine protection device (if equipped)
•
Electrical connectors
Recommended Actions
Logged Codes
Check for any event and active diagnostic codes on
the electronic service tool. Troubleshoot any active
codes before continuing with this procedure.
Fuel Supply
NOTICE
Do not crank the engine continuously for more than
30 seconds. Allow the starting motor to cool for two
minutes before cranking the engine again.
1. Check the fuel pressure. Refer to Systems
Operation, Testing and Adjusting, "Fuel System
Pressure - Test".
2. Ensure that the fuel system has been primed.
Refer to Systems Operation, Testing and
Adjusting, "Fuel System - Prime".
3. Check the diesel fuel for contamination. Refer to
Systems Operation, Testing and Adjusting, "Fuel
Quality - Test".
