2.14.3.2 Sensing plug of oil pressure control principle

Engine oil pressure sensor plug is a pressure switch and is set on the oil filter. 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.
