oil pressure sensor keeps going off
1. The engine lacks oil;
Solution: replenish oil in time.
2. The oil pressure sensor is faulty;
Solution: Repair the oil pressure sensor.
3. The combination meter itself is faulty;
Solution: Repair the combination meter.
4. External electromagnetic interference causes the internal chip of the instrument to malfunction.
Solution: stay away from the source of interference. Extended information:
The main function of oil
1. Lubrication: There is rapid relative sliding between the piston and the cylinder, between the main shaft and the bearing bush. To prevent the parts from wearing too quickly, an oil film needs to be established between the two sliding surfaces. The oil film of sufficient thickness separates the surfaces of the parts that are relatively sliding, so as to achieve the purpose of reducing wear.
2. Auxiliary cooling and cooling: The oil itself does not have a cooling effect due to its low specific calorific value and inside the engine. However, heat energy is generated in the engine due to the combustion of fuel. When the engine is working, the oil can bring the heat back to the oil tank and then dissipate it into the air to help the water tank cool the engine. What really cools is the water (or antifreeze liquid) outside the engine casing.
3. Cleaning and cleaning: Good engine oil can bring the carbide, sludge and wear metal particles on the engine parts back to the oil tank through circulation, and wash the dirt generated on the working surface of the parts through the flow of lubricating oil.
The sensor function failure is caused by poor contact and interference of the wire head connecting the alarm.
1. If the low-pressure fuel pressure sensor fails, the fuel pressure pre adjustment will replace the fuel pressure adjustment. The fuel pressure is approximately 6.5bar. If the low-pressure oil pressure is insufficient for a long time, it may lead to abnormal wear of the fuel pressure regulating valve and seizure, which may lead to the failure of the function of the fuel pressure sensor.
2. If the high pressure oil pressure sensor fails, the fuel system cannot establish high pressure. The engine runs in an emergency with low fuel pressure, resulting in loss of power and torque.
3. The fuel pressure sensor is used to detect the oil pressure change of the fuel pipeline. If it is damaged, the fuel pressure cannot be detected, and the engine computer cannot adjust the fuel pressure according to the working conditions, resulting in weak acceleration and difficult startup.
