Abstract
A first integrated circuit includes a first voltage output circuit for outputting a voltage, which proportionally increases in correspondence to an angular position of a throttle valve, a first protective resistor, a first output terminal connected to the first protective resistor, and a first abnormality detection circuit for outputting a first abnormality detection signal based on a voltage produced by the first protective resistor. A second integrated circuit is configured similarly to the first integrated circuit by a second voltage output circuit, a second protective resistor, a second output terminal, and a second abnormality detection circuit.
