ABNORMALITY DETERMINATION DEVICE OF FUEL PROPERTY SENSOR AND METHOD OF DETERMINING ABNORMALITY OF THE SAME |
摘要 |
An abnormality determination device is applied to an electrostatic capacitance type fuel property sensor that has a sensing section that senses an electrostatic capacitance of a fuel to be detected. The abnormality determination device of the fuel property sensor acquires a first output that is an output when a predetermined voltage is applied to the sensing section and a second output that is an output when a voltage is not applied to the sensing section. The acquired first output and second output are compared and whether or not the fuel property sensor is abnormal is determined. |

1. An abnormality determination device of an electrostatic capacitance type fuel property sensor having a sensing section that senses an electrostatic capacitance of a fuel to be detected, comprising:
a first acquisition section configured to acquire a first output that is an output of the fuel property sensor in a state where a predetermined voltage is applied to the sensing section; a second acquisition section configured to acquire a second output that is an output of the fuel property sensor in a state where a voltage is not applied to the sensing section; and a determination section configured to determine whether or not an abnormality of the fuel property sensor is present by comparing the first output and the second output. |
