Question type: Maintenance & Repair

2000 Ford Taurus. Find great and all of the
sudden I get a check engine light. Go to
AutoZone and they pull the codes. Our of the
blue 9 codes??? All oxygen sensors other
sensors. Is it normal or possible for all of
these to go out at once?

No. The 2 major reasons I have found for multiple codes like that are #1 - a shorted loom: usually a wire loom melted against a hot exhaust manifold or pipe OR, #2 - a bad ECU. What were the codes?

This happened to my girlfriend's '98. But we had 15 codes pop at once. All oxygen sensor related. Turned out to be a really dirty MAF sensor. 5 minutes to clean it. Car ran like new afterwards. No more codes. Figured it makes sense that a dirty sensor at the beginning of the air intake could trip 15 codes all up and down the air system.
