3524B Engines for Off-Highway Trucks E072 Oil Level Low Mark Caterpillar


E072 Oil Level Low Mark
`
Event E072

Conditions Which Generate This Code:

The Electronic Control Module (ECM) detects all of the following conditions:

  • The engine has been running for at least one second.

  • Oil level is low for three seconds.

System Response:

The ECM will log the event. The status of the engine oil is set low. If the oil level recovers for 0.5 seconds the status becomes okay.

Possible Performance Effect:

  • None

Troubleshooting:

  • There may be a problem with engine oil level.

  • There may be a problem with the low oil level switch.

Test Step 1. Check for "ACTIVE" Diagnostic Codes

  1. Connect the AVSpare Electronic Technician (ET) to the service tool connector.

  2. Turn the keyswitch to the ON position. The engine should be off.

  3. Check for any active diagnostic codes or logged diagnostic codes.

Expected Result:

There are no diagnostic codes that are present.

Results:

  • OK - There are no diagnostic codes that are present. Proceed to Test Step 2.

  • Not OK - There are diagnostic codes that are present.

    Repair: Repair the diagnostic codes that are present. Refer to the appropriate topic in the "Troubleshooting With a Diagnostic Code" section of this manual. Ensure that the repair eliminates the problem.

    STOP

Test Step 2. Perform a Check of the Lubrication System

  1. Perform a check of the lubrication system. Refer to the diagnostic procedure Troubleshooting, "Low Engine Oil Pressure" for possible causes.

Expected Result:

There are no problems with the lubrication system.

Results:

  • OK - There may be an intermittent problem.

    Repair: If the problem is intermittent, refer to the diagnostic functional test Troubleshooting, "Inspecting Electrical Connectors".

    STOP

  • Not OK - There are problems with the lubrication system.

    Repair: Repair the problem. Ensure that the repair eliminates the problem.

    STOP
