| CODE | REASON | EFFECT |
| Fault Code: 415 PID: P100 SPN: 100 FMI: 1/1 LAMP: Red SRT: |
Engine Oil Pressure Low – Critical. Engine oil pressure signal indicates engine oil pressure below the engine protection critical limit. |
Progressive engine speed derate increasing in severity from time of alert. If Engine Protection Shutdown feature is enabled, engine will shut down 30 seconds after red Stop lamp starts flashing. |
 Engine Oil Pressure
|
Circuit Description
The engine oil pressure sensor monitors oil pressure and passes information to the electronic control module (ECM) through the engine harness. If the oil pressure becomes too low, based on engine speed, it will cause a derate condition. If the engine protection shutdown is enabled, the engine will shut down 30 seconds after the red stop lamp starts flashing.
Component Location
The engine oil pressure sensor is located on the left side of the engine block, below and to the rear of the integrated fuel system module (IFSM).
Refer to Procedure 100-002 in Section E for a detailed component location view.
Shop Talk
The engine oil pressure sensor measures the pressure of the oil in the oil rifle on the left-hand side of the engine block.
Possible causes of this fault code include:
- Mechanical failures such as lubricating oil pump, lubricating oil high pressure relief valve, loose lubricating oil filter
- Breakdown or contamination of lubricating oil
- Plugged lubricating oil filter.
