Electronic control device for vehicle engine, has correction execution unit, which corrects digitally changed voltage value based on output voltage of constant voltage current supply circuit, and conversion processing data

摘要

The device has a temperature detection sensor (112b) with a heat sensitive unit and a memory. A correction execution unit corrects the value of a digitally changed voltage by a multi-channel analog to digital transducer based on the output voltage of constant voltage current supply circuit (111), and a conversion processing data. The output voltage is approximated by a voltage approximation unit.
