Oil pressure map for the 3056E engineThe Electronic Control Module (ECM) detects the following conditions:
The engine has been running for at least 5 seconds.
The engine speed is at least 350 rpm.
Engine oil pressure is lower than the threshold for low oil pressure for more than 2 seconds.
100-03 "Engine Oil Pressure open/short to +batt" is not active.
100-04 "Engine Oil Pressure short to ground" is not active.
100-10 Engine Oil Pressure Sensor abnormal rate of change is not active.System Response:The ECM will log the event. The ECM will reset the warning when the oil pressure rises 21 kPa (3 psi) above the threshold for at least four seconds.
None
There may be a problem with the engine lubrication system.
There may be a problem with the engine oil pressure sensor.Test Step 1. Check for Active Diagnostic Codes
Start the electronic service tool.
Turn the keyswitch to the ON position.
Check for any active diagnostic codes or logged diagnostic codes.Expected Result:There should be 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 faults that generated the diagnostic codes. Refer to the appropriate topic in Troubleshooting, "Troubleshooting with a Diagnostic Code". Ensure that the repair has eliminated the fault.STOPTest Step 2. Check the Engine Lubrication System
Perform a check of the engine lubrication system. Refer to Troubleshooting, "Low Engine Oil Pressure".Expected Result:There are no faults in the engine lubrication system.Results:
OK - There are no faults in the engine lubrication system. There may be an intermittent fault.Repair: Monitor the operation of the engine. If an intermittent fault is identified, repair the fault. Ensure that the repair has eliminated the fault.STOP
Not OK - There is a fault in the engine lubrication system.Repair: Repair the fault. Ensure that the repair has eliminated the fault.STOP
