What's the reason why the pressure drops quickly after the car diagnostic leak detection equipment is pressed, but the specific leak point cannot be found?

It is not necessarily a major leak in parts, but mostly micro-leakage in hidden locations such as pipe joints, sealing rings, vacuum tubes, valve cores, etc.,

It is not necessarily a major leak in parts, but mostly micro-leakage in hidden locations such as pipe joints, sealing rings, vacuum tubes, valve cores, etc., or the equipment's own interfaces and rubber rings are not tightly sealed, or the pipeline is aging and leaking, causing the pressure gauge to drop pressure, making it difficult to directly detect leaks with the naked eye.
