Abstract
A deterioration detecting apparatus for catalytic converter is provided to surely detect deterioration of a catalytic converter. In the deterioration detecting apparatus for catalytic converter, an electronic control unit decides whether or not a catalyst is activated in the catalytic converter for removing injurious ingredients from an exhaust gas of an engine, and the electronic control unit decides the deterioration of the catalyst only when it decides that the catalyst is activated. It is thereby possible to avoid erroneous decision of the deterioration since the deterioration of the catalyst is not decided when the catalytic converter is not activated.
