From P0AFC P0B47 error code. Pls solution

Happy Easter all.
Because corona virus stay at home, I have not driven my 2012 prius for a weeks now. Only start to warn it like every 4 days. Then I started it and boom this code P0AFC came on. I removed the hybrid battery park cleansed all rust on busbars and battery modules. Touched fuses and relays then put back the battery pavk back. Boom again the P0AFC went off and P0B47 code came on after clearing the previous code. Both gives the same issues. Engine constantly running not going to electric mode. Check hybrid system and triangle of death on. I checked my connections and discovered that i did not connect of of the voltage sensor wire to its bus bar. I have connected it, cleared code and the code P0B47 came back instantly.

Please can someone tell me that to do now?
