<p>Hall ICs (31, 32) constituting a redundant throttle valve position sensor (30) are used to measure a rotational angle value indicative of a position of a throttle valve (12) and a temperature value indicative of an ambient temperature change, which is continuously monitored, around the Hall ICs (31, 32). The rotational angle value measured by the Hall ICs (31, 32) is appropriately adjusted based on the measure temperature value of its own, and a throttle valve position is determined in an externally connected ECU based on the adjusted angle value. In addition, the temperature value measured by one Hall IC (31) is inputted to the ECU. In the ECU, various control values, such as a resistance value of an electric motor (20), can be appropriately adjusted based on the measured temperature value. <IMAGE></p> |
