Engine Oil Pressure
The ECM automatically performs the following functions for low engine oil pressure:
- Warning
- Shutdown
The strategy is based on a map of the engine oil pressure versus the engine rpm. The default settings that are programmed at the factory are listed in Table 1.

| Engine Oil Pressure | |
| Parameter | Default Settings |
| Hysteresis | 20 kPa |
| Activation delay | 10 seconds |
| Security level | Required password |
| Warning setpoint | Map |
| Warning delay | 4 seconds |
| Shutdown setpoint | Map |
| Shutdown delay | 9 seconds |

If the engine oil pressure is below the minimum pressure for four seconds, a warning will occur. To deactivate the warning, the engine oil pressure must rise above the hysteresis that is set in the map.
If the engine oil pressure is below the minimum pressure for nine seconds, a shutdown will occur.
The map cannot be reprogrammed.
