Where is the car oil pressure sensor, and where is the oil pressure sensor generally located?

Generally behind the engine, on the cylinder block, next to the oil filter cartridge seat. There is a plug with a wire on it, which is located on the front oil duct of the oil filter.

The electronic oil pressure sensor consists of a thick film pressure sensor chip, a signal processing circuit, a housing, a fixed circuit board device, and two leads. The signal processing circuit is composed of a power supply circuit, a sensor compensation circuit, a zeroing circuit, a voltage amplification circuit, a current amplification circuit, a filter circuit and an alarm circuit.

Figure 1 is a structural diagram of the sensor, and Figure 2 is a block diagram of the sensor. The thick film pressure sensor is a new type of strain pressure sensor that appeared in the 80s of the 20th century, which is developed by using the piezoresistive effect of the thick film resistance printed and sintered on the ceramic elastomer. Four thick film resistors are directly printed and sintered on a ceramic elastic diaphragm and connected to form a Wheatstone bridge through a conduction belt.

When the measured liquid level pressure acts on the ceramic elastomer, the elastic diaphragm produces deflection deformation, and at the same time, the thick film resistance imprinted on the elastic diaphragm also produces the same amount of strain, in which 2 thick film resistors are compressed by strain, and the resistance value decreasesThe other 2 tensile strains increase the resistance value. In this way, the measured pressure value is converted into a bridge output signal, and the signal size is proportional to the pressure.

Generally on the main oil duct of the engine cylinder head.

There is one, usually behind the engine, on the cylinder block, with a plug with a wire on it, on the front oil duct of the oil filter.

The oil pressure sensor is mounted next to the crankshaft pulley, on the main oil duct of the oil pump. Some imported vehicles do not have oil pressure sensors.

Next to the main oil duct filter or on the rocker arm.

Generally, the oil on the cylinder head must pass through.

The automobile oil pressure sensor can measure the pressure, fuel quantity and car lifting faults in real time, and can timely feedback these faults to the car owner. At the same time, it can also monitor the mileage of the car and provide the power of the engine, so that it can be repaired in time according to the problems and protect the condition of the car.

The pressure sensor is a bit of a monitoring of the nuclear balance oil pressure, if once broken, it will cause the engine to fail, the fault light will also light up, and it will automatically alarm after it is broken, and it needs to be replaced in time to do parts, and the car needs to be maintained after driving 6 70,000 kilometers, which are what everyone knows.

When the oil pressure is insufficient, an alarm will be issued, the fault light of the guess key will also be lit up, and the speed of maintaining the car should not be too fast, and the gear adjustment should be slower when going uphill, and the parts should be replaced in time. Trillion rides.
