oil pressure sensor n14 cummins location
Oil pressure sensor n14 cummins location: The sensor at this position is installed. The oil pressure sensor that comes with the engine is on the left side of the engine, next to the electronic control module, and there is only one wire. If the main engine factory installs it, you have to look for it again. Generally, there are only a few places, above the engine filter seat, and the main oil passage is on the line. Generally behind the engine, on the cylinder block, next to the oil filter seat. There is a plug with a line on it, which is located in the front oil passage of the oil filter element.
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 2 lead wires. The signal processing circuit is composed of power supply circuit, sensor compensation circuit, zero adjustment circuit, voltage amplification circuit, current amplification circuit, filter circuit and alarm circuit. The structure diagram of the sensor, its functional block diagram. Thick-film pressure sensor is a new type of strain-type pressure sensor that appeared in the 1980s. It is developed by using the piezoresistive effect of thick-film resistors printed and sintered on ceramic elastomers. Directly print and sinter 4 thick film resistors on the ceramic elastic diaphragm, and connect them into a Wheatstone bridge through a conduction band. When the measured liquid level pressure acts on the ceramic elastomer, the elastic diaphragm will be deflected and deformed. At the same time, the thick film resistors printed on the elastic diaphragm will also produce the same strain. Among them, the two thick film resistors Under compressive strain, the resistance value decreases; for the other two under tensile strain, the resistance value increases. In this way, the measured pressure value is converted into a bridge output signal, and the signal size is proportional to the pressure.
If it shows 1003 error it maybe the engine oil pressure signal shows that the oil pressure of the engine is lower than the specified value, and the ECM considers it a fault, and stores the fault in the form of fault code 415. At this time, because the oil pressure is too low, the protection function of the engine will work, forcing the power and speed of the engine to drop, and the engine may be turned off for protection. The oil pressure sensor is installed on the cylinder block, and the oil pressure sensor circuit.
