Maybe some of the sensor connectors were incorrectly installed. This happened to a guy I met one time. He bought a Volvo 850T that had an engine replaced with one from a junkyard, excuse me, Automotice Recycler. It was setting codes left and right. He finally decided to check all the engine wiring harness connections and found several were plugged into the wrong place. Once he fixed that, the car ran great. No more codes.
