Abstract
A gas sensor system () including a gas sensor () and a sensor control section () including detection circuits (), () and () for detecting the terminal potentials V, V, and Vof first to third terminal Tthrough T. The sensor control section () includes a circuit () for applying an examination potential Vex to the second terminal T, a first circuit () which has a predetermined resistance Rand disconnectably connects the first terminal Tand the second terminal T, a second circuit () which has a predetermined resistance Rand disconnectably connects the second terminal Tand the third terminal T, and terminal potential detection means Sfor detecting the terminal potentials V, V, and Vusing the detection circuits in a state in which the examination potential Vex is applied to the second terminal Tand switches SWand SWare turned on.
