Knock sensor code after new one installed

Question

I' replaced the knock sensor twice with original product. I heard in 2007 there was a service bulletin about a software update for false positive random dtc's. So after two knock sensor replacements and still getting it I now have a tire pressure warning light and a crank sensor dtc which both have gone away. I did have an issue with it not going over 4000 rpm's no mater what the load was but it has gone away both times and runs ok now. It's done that twice now and thinking that could be causing crank sensor code but not sure. Does anyone know about a software issue in 2008?
