Oil Pressure Sensor
The oil pressure sensor detects the size of the engine oil
pressure when it is working, and it is usually screwed into
the oil passage of the cylinder block. Its working principle
is that there is a variable resistor inside the sensor, one
end outputs the signal, and the other end is connected
to the grounded sliding arm. When the oil pressure
increases, the oil pressure pushes the diaphragm
through the lubricating oil channel interface to bend, and
the diaphragm pushes the sliding arm to a low resistance
position, which increases the output current in the circuit,
and vice versa, reduces the output current in the circuit.

in the fi gure below). The sensor is a normally
open contact, the working pressure is 250±10kPa,
and the maximum working temperature is greater than
150°C. When the oil pressure is too low, the oil pressure
indicator on the instrument is always on.
A
Fault diagnosis
◆
When there is no oil pressure indicator, it is
generally because the wiring harness connector is
poorly connected.
◆
When the wiring harness connect or is well
connect ed, the sensor itself is fault y. I t is
recommended to replace the sensor with a new one.
!
When an oil pressure failure occurs, you must
troubleshoot the failure. Forcible operation will damage
the engine.
