Disclosed is a method for diagnosing deterioration of an intercooler. According to an embodiment of the present invention, the method for diagnosing deterioration of an intercooler may comprise the following steps of: determining whether an engine RPM, an engine rotating speed, an atmospheric temperature, and an atmospheric pressure are in a preset range; calculating a deviation between a temperature detected by an intercooler outlet temperature sensor and a temperature detected by an air flow sensor when all of the engine RPM, the engine rotating speed, the atmospheric temperature, and the atmospheric pressure are determined to be in the preset range; and determining that the intercooler deteriorates when the determined deviation is determined to be equal to or more than a preset reference error value. |
