Beschreibung
Zusammenfassung:	A gas sensor system (1) including a gas sensor (2) and a sensor control section (40) including detection circuits (41), (42) and (43) for detecting the terminal potentials V1, V2, and V3 of first to third terminal T1 through T3. The sensor control section (40) includes a circuit (44) for applying an examination potential Vex to the second terminal T2, a first circuit (45) which has a predetermined resistance R1c and disconnectably connects the first terminal T1 and the second terminal T2, a second circuit (46) which has a predetermined resistance R2c and disconnectably connects the second terminal T2 and the third terminal T3, and terminal potential detection means S5 for detecting the terminal potentials V1, V2, and V3 using the detection circuits in a state in which the examination potential Vex is applied to the second terminal T2 and switches SW1 and SW2 are turned on.
