Abstract
Provided is a sensor signal output apparatus that outputs a sensor signal at times of the sensor being in steady operation and outputs the operational status of the sensor instead of the sensor signal when the sensor is at fault or in non-steady operation in order to thereby to have a receiver machine obtain a correct sensor signal. The sensor signal output apparatus includes a sensor detecting a physical quantity, a diagnosis part diagnosing the operating state of the sensor, and a communication part transmitting the result of detection by the sensor and the result of diagnosis by the diagnosis part. When the sensor is determined to be normally operating, the communication part selectively outputs the result of detection by the sensor. When the sensor is not determined to be normally operating, the communication part selectively outputs a signal indicative of the operating state of the sensor.
