2.9.3.2 Engine Oil Pressure Alarm Control Principle

Engine oil pressure alarm is a pressure switch and set on the engine main oil piping. When the
engine oil pressure is below the specified value, this switch is switched off and the engine oil
pressure warning lamp in the instrument will be on. When the car starts normally, the oil pump
transfers the oil pressure to the system, so this switch is switched off and the engine oil pressure
warning lamp in the instrument will be off.
