Abstract
An apparatus for diagnosing a post-processing system includes a first catalyst, an exhaust heat recovery system, and a second catalyst sequentially disposed on an exhaust line. The apparatus further includes a main bypass line, an auxiliary bypass line, a first bypass valve, and a second bypass valve. The apparatus further includes a controller configured to determine whether a first temperature sensor configured to measure a temperature of an exhaust gas on an upstream side of the first bypass valve, a second temperature sensor configured to measure a temperature of the exhaust gas on an upstream side of the exhaust heat recovery system, a third temperature sensor configured to measure a temperature of the exhaust gas on the downstream side of the exhaust heat recovery system, the first bypass valve, and the second bypass valve are abnormal, depending on whether a predetermined diagnosis condition is satisfied.
