O2 not updating

I have MS2 on V3 board running 2.89 code. I am using a 14.7 NAW WBO2 that was working perfectly fine with megasquirt for a while. After my car stalled and I tried to start but the battery was too low it stopped updating the O2 value. I have re-flashed the ECU with 2.89, I have tried tunerstudio and ...
