Update: This is resolved.
So, after I put in the replacement sensors and got both P1140 and P1145 codes, I took them back out and put the original sensors back. I expected to only see one code like I initially did. But the 2 codes never went away. I drove for probably 50 miles. I also couldnt get my Oxygen monitor to set, even after running through the drive cycle repeatedly.
I ended up clearing the codes and driving for a bit. After a few miles, only the P1145 came back. This was good, as I was hoping only one code would come back. Since I hadnt cleared the codes when I put the replacement sensors in the first time, I thought I'd give it another try. I replaced the bad sensor with one of the replacements, cleared the codes, and drove for a bit. Sure enough, all my monitors set (including Oxygen) and no more code. Immediately got a SMOG test and passed.
So, the non-OEM part wasn't bad. I just needed to clear the codes first. That being said, in the future I will just buy an OEM sensor to rule out the possibility of a junk third party sensor.
