P0688 DODGE - Auto Shutdown Relay Control Circuit Low

P0685 DODGE - Auto Shutdown Relay Control Circuit Failure

Just had the computer replaced in the car. The dealer I got the car from said the ac issue I was having was due to it being bad. So it was replaced and Dodge programmed it. Well now 3 weeks later I'm getting these two codes plus a P0052. O2 sensor Bank 2 sensor 1 failure. I just replaced both bank two sensors and reset the computer but still get these codes. I'm thinking it's a faulty new computer but wanted some input from everyone first. I've checked all fuses all wiring all relays are tight and all grounds that I could see are snug and landed. Thoughts?
Dodge has to make a better obd most of all the problems are because of a bad obd you can get a new one an in a month about it will go bad an you wont think its bad but it will be they need to fix that problem
