Which entry should be used when the oil filler cap is broken?

• A. Enter A for Absent Cap.
• B. Enter C for Cracked Cap.
• C. Enter B for Broken Cap.
• D. Enter D for Defective under Other Emission Related Components.

Answer: (D)

When a part of the evaporative emissions system is damaged, you classify it by how it affects emissions rather than by the exact physical state of the component. A broken oil filler cap still alters the system’s ability to seal vapors, so it’s considered an emission-related defect. The correct entry is the one that covers a defect in Other Emission Related Components, because this is the general category used for emission-related failures that don’t fit more specific labels like absent, cracked, or broken cap.

An absent cap would mean the cap is missing entirely, which isn’t the case here. A cracked cap implies a crack but not a complete break, and a broken-cap label isn’t the category used in this context. The broad “defective under Other Emission Related Components” option best captures the issue’s impact on emissions without trying to force the cap into a more specific label.
