When conducting an audible air leak inspection, what indicates a minor defect?

A minor defect during an audible air leak inspection is indicated by the fact that the leak can be clearly heard. This suggests that while there is an issue with the air system, it may not be severe enough to cause immediate concern regarding vehicle operation. A clear sound of air escaping signals a minor leak, which could potentially be addressed quickly without significantly affecting the performance or safety of the vehicle.

On the other hand, if the air leak cannot be heard, it implies there may not be a detectable issue, which challenges the idea of a defect at all. A constant sound of air escaping would typically signify a more significant problem, indicating a larger leak that warrants further investigation and action. Similarly, if the vehicle shows no pressure loss, it suggests that the air system is functioning properly without any leaks of concern.
