i wasnt sure how to do it on ym 97 conrour, so i disconnected the neg side of the battery (because my amp and other [censored] is wired to the pos side) and took out all them fuses from the box under the hood and waited a min then put it all back in
i did this to clear the CEL just after replacing the o2 sensor that threw the CEL (the light hasnt come back)
