What does a catalytic deficiency in a Lexus LX470 mean?

A catalytic deficiency in a Lexus LX470 refers to a problem with the vehicle's catalytic converter, which is responsible for reducing harmful emissions by converting pollutants in the exhaust into less harmful substances. This deficiency can lead to increased emissions, reduced engine performance, and may trigger the check engine light. It often results from issues like clogging, damage, or failure of the catalytic converter, which may require repair or replacement to ensure compliance with emissions standards and maintain optimal engine function.
