C4.4 and C6.6 Engines for Caterpillar Built Machines E360 Low Engine Oil Pressure Caterpillar

Conditions Which Generate This Code:

The following conditions occur:

360-1

• The engine has been running for at least ten seconds.

• There are no active diagnostic codes for the oil pressure sensor or for the atmospheric pressure sensor.

• Engine oil pressure is in the "LEVEL 1" area in Illustration 1 for eight seconds.

Note: The warning will be cancelled if the oil pressure rises 21 kPa (3 psi) above the set point for 20 seconds.

360-2

• The engine has been running for at least ten seconds.

• There are no active diagnostic codes for the oil pressure sensor or for the atmospheric pressure sensor.

• Engine oil pressure is in the "LEVEL 2" area in Illustration 2 for eight seconds.

Note: The derate will be cancelled if the oil pressure rises 21 kPa (3 psi) above the set point for 20 seconds.

360-3

• The engine has been running for at least ten seconds.

• There are no active diagnostic codes for the oil pressure sensor or for the atmospheric pressure sensor.

• Engine oil pressure is in the "LEVEL 3" area in Illustration 3 for four seconds.

Level 2 engine oil pressure versus engine speed

Illustration 3	g01269384
Level 3 engine oil pressure versus engine speed

System Response:

360-1

The ECM will generate a SPN 100-FMI 17 event code on the J1939 data link. This will generate a warning on the display on the control panel while the warning is active.

The ECM will generate a E360-1 event code.

360-2

The ECM will generate a SPN 100-FMI 18 event code on the J1939 data link. This will generate a warning on the display on the control panel while the warning is active.

The ECM will generate a E360-2 event code.

The electronic service tool will display "Engine Derate" in the first "Engine Status" box on any status screen on the electronic service tool.

360-3

The ECM will generate a SPN 100-FMI 01 event code on the J1939 data link. This will generate a warning on the display on the control panel while the warning is active.

The ECM will generate a E360-3 event code.

Possible Performance Effect:

360-1

Engine operation is not affected.

360-2

The ECM will derate power by 17.0 percent per second up to a maximum of 100 percent while the derate is active.

360-3

The ECM will derate power by 17.0 percent per second up to a maximum of 100 percent while the derate is active.

The engine will not shut down in this application.

Troubleshooting:

Test Step 1.

Refer to Troubleshooting, "Low Engine Oil Pressure".

Results:

• OK - STOP
