What condition must the air pump NOT be in to be considered acceptable?

The air pump is a critical component in the performance of many vehicle systems, particularly those related to emissions control. For a vehicle to pass inspection, the air pump must be functional and in a condition that allows it to effectively assist in reducing vehicle emissions. When the air pump is excessively cracked or missing pieces, it cannot operate effectively. This condition could lead to diminished air flow or complete failure of the pump, resulting in increased emissions and potential violation of state regulations.

In contrast, conditions such as being new and unused, loose or removed, or well-maintained and intact can vary in their implications. A new and unused pump may still need to be properly installed to be effective, while a loose or removed pump would obviously not work as intended but could potentially be addressed before recertification. A well-maintained and intact pump is ideal and demonstrates that the component is in good working condition. Therefore, the emphasis on ensuring that the air pump is not excessively cracked or missing pieces is crucial for maintaining the vehicle's performance and compliance with inspection standards.
