Abstract
A failure diagnosis method of a temperature sensor of a switch device is provided. The method includes setting a sampling period using a temperature detected by the temperature sensor of the switch device and a temperature of cooling water for cooling the switch device. A temperature sensing value detected by the temperature sensor is then compared with a temperature reference value stored in a memory in the sampling period to determine whether failure occurs in the temperature sensor.
