What's with the flashing of the car oil lamp?

The alarm of insufficient oil pressure needs special attention. Insufficient oil pressure does not mean insufficient oil. Even if the oil reaches the F scale, it just means that there is no shortage of oil. In fact, the pressure of oil is generated by the oil pump and transported to the parts that need lubrication through the oil circuit of the engine. I think the oil is stored at the bottom of the engine and can lubricate the upper part of the engine through the power of the oil pump. There are two possibilities to solve the problem of insufficient oil pressure. First, there is something wrong with the oil sensor, just replace the sensor. Second, insufficient oil pressure is troublesome. Common causes of insufficient oil pressure include severe wear of crankshaft and bearing, damaged oil pump or insufficient oil pressure. To solve this problem, you need to go to a professional repair shop for inspection and maintenance. The flashing of automobile oil lamp generally indicates that the oil pressure is insufficient, but it may also be a false alarm. For example, there is something wrong with the sensor plug. In this case, the following measures need to be taken: first, check whether the engine oil is insufficient, and at the same time, check the plug of the engine oil sensor; Secondly, verify whether the oil filter has quality problems; Then directly measure the actual oil pressure with the oil meter; If there is no problem in the actual measurement, there may be a problem with the sensor plug; Finally, if there is a practical problem, the cause of the problem is likely to be the oil pump, the crankshaft bushing clearance or the pressure valve of the lubrication system. In addition, the oil filter in the oil pan may be blocked, which requires close attention.
