Where is the oil pressure sensor located on the Mercedes-Benz 274 engine?

The oil pressure sensor on the Mercedes-Benz 274 engine is generally located at the rear of the engine, on the cylinder block, next to the oil filter housing. Introduction to the pressure sensor: The electronic oil pressure sensor consists of a thick-film pressure sensor chip, signal processing circuit, housing, fixed circuit board assembly, and two leads. The signal processing circuit includes a power supply circuit, sensor compensation circuit, zero adjustment circuit, voltage amplification circuit, current amplification circuit, filtering circuit, and alarm circuit. Working principle of the pressure sensor: When the measured liquid pressure acts on the ceramic elastic body, the elastic diaphragm undergoes deflection deformation. Simultaneously, the thick-film resistors printed and fired on the elastic diaphragm experience the same amount of strain. Among them, two thick-film resistors are subjected to compressive strain, resulting in a decrease in resistance value, while the other two are subjected to tensile strain, leading to an increase in resistance value. In this way, the measured pressure value is converted into a bridge output signal, with the signal magnitude being proportional to the pressure.
