Who correctly defines "tampered" in relation to emission components?

In the context of emissions components, "tampered" refers to any modifications or alterations made to the vehicle's emission control system that are intended to reduce its effectiveness or bypass the intended pollution controls. Technician B likely provides a definition that accurately captures this concept, including the notion that tampering can lead to increased emissions and violate regulatory standards.

A correct definition typically encompasses actions such as removing, disabling, or altering emission control devices like catalytic converters, oxygen sensors, or On-Board Diagnostics (OBD) systems. Understanding this term is critical for a smog check inspector, as distinguishing between a vehicle that is operating within its emissions limits and one that has been tampered with is essential for ensuring compliance with environmental regulations.

If the other technician fails to recognize the full implications of what "tampered" means or does not accurately reflect the consequences of such actions, it would further reinforce why only one of the technicians provides a correct definition.
