摘要：
Disclosed is a technology of diagnosing an exhaust gas purifying apparatus about a fault in its temperature control function of controlling a temperature of an exhaust gas purifying catalyst. The exhaust gas purifying apparatus for an internal combustion engine includes the exhaust gas purifying catalyst, and a temperature control means for controlling the temperature of this exhaust gas purifying catalyst. The exhaust gas purifying apparatus is judged to be faulted, wherein at least one of a state of the temperature control means and a state of the exhaust gas purifying catalyst serves as a parameter.
