Morphology
The literal combination of 'nose' (sense organ/ability to detect) and 'knows' (is aware) gives a clear cue that it refers to sensing or perceiving, so learners can infer something about detection. However, the leap from physical smelling to the abstract idea of reliable intuition/instinct is metaphorical and somewhat idiomatic, so the precise meaning (trustworthy instinct about something suspicious) is not fully predictable without exposure.
Etymology
The nose knows comes from the simple image of a nose that smells things others miss, like an animal sniffing danger or food. So the saying means 'trust your instinct' because your quick feeling can notice when something is right or wrong.
