Code 12, 13, and 25 all at the same time

Something seems fishy with all 3 sensors going out at the same time. Aren't they all on the same plug? What would you guys look for? So far I've tried starting it with the plug disconnected, then reconnected it, pulled the sensor assembly off the engine. Just little things like that. None of that has changed anything. Also, when I reset the ECU it doesn't seem to refresh. As soon as I hit the key it says those sensors are out. Anyone run into this problem?

Try using a replacement MAS assembly. If that doesn't work, check to see if that plug is getting a good ground (Pin 6, green/black) and a proper 5v supply (pin 4, green/red)

How do you check for good ground? I'm getting the same issue.

And I thought the 5V (4.8-5.2V or whatever) supply was for pin 2?
