An open check circuit for a sensor, comprising a check mode section and a sensing mode section that performs a sensing operation in response to a high signal from the controller after an open check. In the open check circuit for a sensor according to claim 1 of the utility model registration claim, the open check mode section is such that the open check resistor in which the open check transistor is turned on and the sensor are connected in series to a power supply and are grounded. That's what happens. Utility Model Registration In the open check circuit for a sensor according to claim 1, the sensing mode section is formed by a sensing mode resistor in which a sensing transistor is turned on, connected in series with the sensor, and grounded. Utility Model Registration In the open check circuit for a sensor according to claim 1, the open check mode section and the sensing mode section have the emitter of the open check transistor and the collector of the sensing transistor connected in parallel, and this parallel connection is common. A sensor is connected to the contact,
Something that is grounded.
