How can catalytic converter theft affect emissions testing?

Catalytic converter theft significantly impacts emissions testing outcomes because the catalytic converter plays a critical role in managing vehicle emissions. The primary function of a catalytic converter is to reduce harmful pollutants in exhaust gases by converting them into less harmful substances before they are released into the atmosphere.

When a catalytic converter is stolen, the vehicle's exhaust system becomes compromised, resulting in an inability to adequately filter and convert exhaust gases. This directly leads to an increase in the release of harmful emissions such as nitrogen oxides, carbon monoxide, and hydrocarbons. Consequently, during emissions testing, a vehicle operating without a catalytic converter will likely fail, as the emissions levels are elevated and exceed regulatory standards.

This understanding emphasizes the importance of the catalytic converter in both the vehicle's performance concerning emissions control and the necessity of its presence for successful emissions testing outcomes.
