This engine oil pressure sensor monitors the oil pressure in the host engine and sends a signal to the control unit or gauge. It is installed in the engine block, where it reads the pressure of the lubricating oil as it circulates through the main galleries. A failing sensor may cause a false low-pressure warning or prevent the warning light from illuminating, which can lead to undetected oil starvation. This component is manufactured by AGCO to match the original thread and sealing interface of the engine block, ensuring a proper seal without the need for adapters. When replacing, apply thread sealant to the sensor threads and torque to the engine manufacturer's specification.
