PURPOSE: A method for detecting a sensor value error by applying a variable value is provided to prevent time waste, to reduce costs, and to improve power efficiency. CONSTITUTION: A method for detecting a sensor value error by applying a variable value is as follows. When fixed measurement value is input, whether the malfunction of the sensor is existed or not is confirmed by applying a different variable value. The variable value is a measured vale or a different value. If the post measurement value of the sensor is identical to the prior measurement value, the malfunction of the senor is not existed. If the measurement value is identical to the variable value, the malfunction of the sensor is existed. When the sensor value error is confirmed, error information is transmitted to a sensor value receiving unit.
