Abstract
A gas sensor processing apparatus () which includes voltage shift means (, S) for shifting a detection element voltage VE produced between electrodes (P,N) of a detection element () from a pre-shift voltage VEto a post-shift voltage VErecovery means (, S) for returning the detection element voltage VE from the post-shift voltage VEto the pre-shift voltage VEafter the end of a voltage shift period TS in which the voltage VE is shifted by the voltage shift means; and deterioration index detection means S-Sfor detecting a deterioration index ID representing the degree of deterioration of the detection element () on the basis of a voltage change in the recovery period TK in which the voltage VE is recovered by the recovery means.
