Under which category do Add-On Aftermarket Parts visually inspected?

• A. Other Emission Related Components/Systems
• B. Powertrain Control
• C. Air Conditioning
• D. Fuel Delivery

Answer: (A)

Add-On aftermarket parts that relate to the emissions control system are placed in the category of Other Emission Related Components/Systems. This category serves as the catch-all for parts added outside the stock configuration that can affect how the emissions system works. Inspectors look for these aftermarket items to ensure they’re properly installed and don’t disable or improperly modify emissions controls.

The other categories don’t fit because they cover different system areas: Powertrain Control focuses on engine management and control electronics; Air Conditioning is about the climate system; Fuel Delivery covers the fuel system components. None of those specifically target aftermarket additions that influence emissions like EGR, catalytic converters, or related emissions components.
