SPN100 FMI1
Engine Oil Rifle Pressure - Data Valid But Below Normal Operating Range - Most Severe Level
CODES:
Fault Code: 415
PID(P), SID(S): P100
SPN: 100
FMI: 1/1
Lamp: Red
REASON: The engine oil pressure sensor indicates oil pressure is below the engine protection critical limit.
EFFECT: Progressive power and/or speed derate increasing in severity from time of alert. If the Engine Protection Shutdown feature is enabled, the engine will shut down 30 seconds after the red STOP lamp starts flashing.
Circuit Description:
An engine oil pressure switch or oil pressure sensor is used by the engine control module (ECM) to monitor the lubricating oil pressure. For engines with an oil pressure switch, the switch is normally closed when the engine is not running and open when oil pressure is present. For engines with an oil pressure sensor, the ECM will detect a low signal voltage at operating conditions when the oil pressure is low. The ECM will detect a high signal voltage at operating conditions when the oil pressure is high.
Component Location:
The engine oil pressure sensor is located in the oil rifle.
Conditions for Running the Diagnostics:
This diagnostic runs continuously when the keyswitch is in the ON position or when the engine is running.
Conditions for Setting the Fault Codes:
The Engine Control Module (ECM) detected the engine oil pressure was below minimum operating limits.
Action Taken When the Fault Code is Active:
• The ECM illuminates the red STOP ENGINE lamp immediately after the diagnostic runs and fails.
• The torque output of the engine will be reduced.
• The engine will be shut down if the Engine Protection Shutdown feature is enabled.
Conditions for Clearing the Fault Code:
• To validate the repair, perform a key cycle, start the engine and let it idle for 1 minute.
• The fault code status displayed by the recommended Cummins® electronic service tool or equivalent will change to INACTIVE immediately after the diagnostic runs and passes.
• The ECM will turn off the red STOP ENGINE lamp immediately after the diagnostic runs and passes.
• The "Reset All Faults" command in the recommended Cummins® electronic service tool or equivalent can be used to clear active and inactive faults.
Shop Talk:
Possible causes of this fault code include:
-Low oil pressure
• Incorrect oil level
-Damaged oil pressure switch
-Engine harness shorted to ground.
