oil pressure sensor blinking
Reasons for the oil pressure warning light on:
1.Insufficient oil, lower than the standard value, check whether there is leakage;
2.The viscosity of the oil is not enough, too thin or too thick;
3.The oil pump is not working well, and the oil supply capacity Poor;
4.The oil circuit from the oil pump to the oil pressure sensor is blocked;
5.The oil pressure is too low;
6.The sensor is faulty;
7. There is a problem with the instrument.
If the oil quantity is normal and the oil viscosity is appropriate, but the oil pressure indicator light stays on after the engine is started, it means that there is a problem with the engine, such as oil pump problem, oil circuit blockage, excessive bearing damage, oil filter blockage, oil pressure limiting valve, oil Pressure indicator light control circuit failure, etc. , it should be sent to the repair shop immediately. In a lubrication system, the oil pumped by the oil pump must ensure proper pressure before it reaches any lubricated parts of the engine. If the set pressure of the pressure limiting valve is too low, the pressure regulating spring will become very soft, and the set pressure will be too low due to improper operation or leakage of the sealing surface. In conclusion, please handle with care when the oil warning light on the dashboard is on. You'd better go to the garage and check it out. Small problems that are not dealt with in a timely manner are likely to cause major problems.
Why does the oil pressure warning light come on?
Under normal conditions, the oil pressure warning light is on, indicating that the oil pressure in the engine oil circuit is lower than the oil pressure lower limit value required by the lubrication system, indicating that an abnormal situation has occurred in a certain link of each component of the engine lubrication system, and the natural problem may also be caused by one or more positions of the integral lubrication system. It can be roughly reflected in the two aspects of lubricating oil and mechanical equipment.
The details are as follows:
(1)The amount of lubricating oil in the engine oil pan is insufficient, the type of lubricating oil is not suitable or the viscosity is too low; the anti-foaming function of the lubricating oil is poor, so that the gas is mixed into the oil circuit;
(2) The diaphragm of the fuel injection pump is cracked, so that the gasoline leaks into the engine oil the sump, or cooling circulating water leaks into the engine oil sump, diluting the lubricating oil, because the cylinder head gasket is damaged or there is a gap in the bushing.
