This part is the engine oil pressure sensor , a small but vital electronic component for your JAC GS3 . Its primary function is to continuously measure the oil pressure inside the engine. The sensor sends this pressure reading to the car's computer and dashboard. If the pressure drops to a dangerous level, the sensor sends an immediate alert, illuminating the oil warning light on the dashboard, thus warning the driver to prevent engine damage due to insufficient lubrication.
If you notice the oil pressure warning light on the dashboard illuminating or flashing (especially after an oil change or when the temperature is high), or oil leaking from the sensor mounting area, the sensor itself may be damaged and giving incorrect readings or need to be replaced.
⚠️ Important Notice: Please make sure the part matches your vehicle's chassis number before purchasing the product or after ordering.
