Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Functional description
The engine-oil pressure sensor employs a capacitative measuring procedure to monitor the absolute pressure. The absolute pressure required for a more precise oil-pressure control. Within the engine oil-pressure sensor is a ceramic plate containing gold platelets. The oil pressure from the oil passage changes the distance between the platelets to vary the capacitance. The electronic processing circuit measures the capacitance. Once evaluated, the data is transmitted to the engine control unit as an input signal for oil-pressure control.
