Which term covers a component that has been changed so that there is no capacity for connection with or operation of other emissions control components or systems?

• A. Not Applicable
• B. Modified
• C. Tampered
• D. Disconnected

Answer: (B)

When a component has been changed so it can no longer connect with or operate with other emissions control components, the term used is modified. This describes any alteration from the original state that prevents proper interconnection and functioning within the system. It’s about the change itself and the resulting loss of compatibility, not just a physical disconnection or a use of the wrong part. Tampering implies a deliberate attempt to defeat the system, which carries a different implication; disconnecting would mean the part is no longer attached at all, rather than being altered to prevent interaction. Not applicable doesn’t fit the situation either. So, modified best fits the scenario.
