Check engine light: O2 sensor? S70 1998

My check engine lite came on after some mild hesitation during part throttle and gear change intervals.

My suspicion is the O2 sensor is going out of whack (still original one from factory). Could there be anything else to look out for? Haven't gotten the fault codes out yet, the dealer wants $$ for it and I'm gonna take my guesses first before pulling codes.
