| Title of Invention | A FAULT DIAGNOSIS DEVICE FOR DIAGNOSING FAULT OF SENSOR FUNCTION IN AN OUTPUT CONTROL APPARATUS |
|---|---|
| Abstract | A fault diagnosis method for diagnosing a sensor function in an apparatus for controlling an output by using a 1-chip microcomputer which receives an electric signal from a sensor for converting a physical quantity into the electric signal, comprising the steps of: driving a drive circuit for driving the sensor with a drive signal issued from the 1-chip microcomputer; said 1-chip microcomputer receiving an electric signal on the basis of the sensor during normal operation by issuing the drive signal, and receiving an electric signal on the basis of the sensor at a predetermined specific value during stopping of the drive signal; and diagnosing a fault of the sensor function when the electric signal of the predetermined specific value is not received during stopping of the drive signal, thereby detecting a fault of sensor function even if a sensor output settles within an output range of the sensor. |
