P0053 even after replacing upstream oxygen sensor
I picked up a 2014 1.4L with 127k on it for my daughter. On the way home CEL came on with a code of P1011. After replacing the MAF Sensor and digging into air leaks and all sorts of fun stuff, I'm still left with a P0053 Heated Oxygen Sensor (HO2S), Bank 1, Sensor 1. This upstream sensor was replaced with one from Amazon (a.co/d/6otqkRy) while I was troubleshooting the original P1011 issue.
I'm also waiting for emissions readiness tests to come to readiness, one of which is the Oxygen Sensor test, although the Oxygen Sensor Heat readiness monitor recently came on as ready.
Is there something else I should be looking at, or is it possibly due to the generic sensor not being a GM part?
Things that were replaced at this point going through the P1011 code:

- Air filter
- MAF Sensor
- Upstream O2 Sensor
- Canister Purge Valve
- MAP Sensor
- PCV Valve Hose
- Intake Air Temperature and Pressure Sensor
