What are the reasons for the oil pump light to come on?

[MacEsther]

The reasons for the oil pump light to come on are as follows:1. Pressure relief valve blockage: To prevent excessive oil pressure in the lubrication system, which increases engine power consumption and causes oil leaks at sealed connections, a pressure relief valve is installed in the main oil passage or oil pump. A malfunctioning pressure relief valve will result in abnormal oil pressure.2. Insufficient oil volume: If the oil volume is insufficient, the oil pump's output will decrease or fail to pump oil due to air intake, leading to a drop in oil pressure and causing the oil light to illuminate.3. Engine overheating: Excessive engine temperature accelerates the aging, deterioration, and thinning of the oil, causing it to leak from various fitting gaps and reducing pressure.4. Oil filter blockage: When the oil filter is blocked and cannot circulate, the bypass valve on its base opens, allowing oil to enter the main oil passage without filtration. If the opening pressure of the bypass valve is set too high or too low, the oil pump pressure will rise or fall accordingly.
