Nissan Murano: System / Engine Protection Control at Low Engine Oil Pressure
SYSTEM DIAGRAM
SYSTEM DESCRIPTION
-
The engine protection control at low engine oil pressure warns the driver of a decrease in engine oil pressure by the oil pressure warning lamp before the engine becomes damaged.
-
When detecting a decrease in engine oil pressure at an engine speed less than 1,000 rpm, ECM transmits an oil pressure warning lamp signal to the combination meter. The combination meter turns ON the oil pressure warning lamp, according to the signal.
-
When detecting a decrease in engine oil pressure at an engine speed 1,000 rpm or more, ECM transmits an oil pressure warning lamp signal to the combination meter.
The combination meter turns ON the oil pressure warning lamp, according to the signals. When detecting a decrease in engine oil pressure, ECM cuts fuel if the engine speed exceeds the specified value.
| Decrease in engine oil pressure | Engine speed | Combination meter | Fuel cut |
|---|---|---|---|
| Oil pressure warning lamp | |||
| Detection | Less than 1,000 rpm | ON* | NO |
| 1,000 rpm or more | ON | YES |
*: When detecting a normal engine oil pressure, ECM turns OFF the oil pressure warning lamp.
