Having an odd issue. Been trying to diagnose lean fuel trim codes using the torque app. Both banks were displaying trims in the app, now I'm not getting any information from bank 1. Just before this happened, I forgot the car was in gear and stalled it out releasing the clutch. Could I have jarred something loose?
I did find some minor vaccum leaks, the remaining bank I can see is low on hot idle and increases at higher rpm so I'm thinking fuel filter or soft failing pump for my codes anyway. also getting very low voltage readings from downstream 02 sensor on bank 1. Could this be an ecu issue or just a bad sensor?

Check the fuel system status of bank 1 at hot idle. It should be 2 Closed Loop. If it is 8 system fault, then the pre-cat O2 sensor is faulty
 
Getting "open loop system fail" using the torque app, so probably too generic for a specific system fault?

Reset codes with the pin connector under the hood, and bank 1 trim numbers returned and entered closed loop!
