Suggestions for code P0135, after new sensor installed and fuses confirmed?

Question

05 Chevy Suburban was displaying P0053, P0135 and P0332 codes. I replaced the Bank 1 Sensor 1 sensor, expecting that to clear the first two codes. P0053 is gone, but P0135 came right back. I confirmed that both oxygen sensor fuses under the hood are good. Any thoughts on what might be still tripping it?

I have to admit one other embarrassing part of facts and circumstances. I had a faulty ground a while back that all of a sudden caused my battery to drain. Jumped it once to get it going and it fired right up. Thought I'd fixed the problem but came out the next morning late for work (of course) and battery was dead. In a rush and frustrated, I didn't quadruple check the jumper cables and connected them backwards on the Suburban. Won't do that again. Would turn over, but not start. Fried my crank position sensor. Got that replaced and it fired right up, but was throwing those three codes listed above.

Wondering if the PCM might be damaged and causing the P0135, and in need of replacement.

I know, I know...I'm a dummy. But I won't make that mistake again!

Thanks!

There are 2 codes for the 02 sensor Bank 1 Sensor 1 , This situation happens all the time from part store to auto shops what goes out is the fusable link, The ECM is very well protected for this situation but all ECM are not well protected from a/c ripples that a alternator produces, a/c ripples do the ECM killing and this is from a bad battery where the negative part of the battery has to ground the magnetic flux . A good battery is always a sure thing. Because of what happened replace the IGN 1 relay, and keep what you have as a spare, what happens it will one day fail. P0135 if it is not the connection then its the 02 sensor, and P0135 can not be caused because the battery revers polarity. If it was your the only one in the world that  happened to. As for the knock sensor same situation, if you replace the knock sensor make sure you use silicone to weather proof on the seal to prevent water from going in there creating rust
