The way OBDs work, if the O2 sensor was bad and it was replaced, the CEL should eventually clear once there are enough cold starts without an error present.

Just saying...

Any cheap OBD readers should be able to reset the codes/CEL. If the CEL comes back immediately, you'll know it wasnt an O2 sensor.
