Abstract
A gas sensor control apparatus () for controlling a gas sensor () includes a change amount detection means (); an element resistance detection means for detecting the element resistance Rpvs of a sensor element section () on the basis of the response change amount ΔVs; a heater energization control section for on-off controlling the supply of electric current to a heater section () by pluses PS having a fixed period T; and an instruction signal output section for instructing the change amount detection section () to detect the response change amount ΔVs at a third timing twhich comes after elapse of a predetermined wait time TW from a second timing t(heater energization off) which changes in accordance with the pulse width PSW.
