Not really...because the MAP sensor is actually a boost controller that works with the cruise. Its located in the engine bad against the firewall. It looks like a little black box on the drivers side of the car. You know it's that for sure if your cruise isn't working. I found this out about 3 months ago. I went to a junk yard and got one out of a old 97 b14 sentra for like 8 bucks or so. Swapped them out with basic tools. And all is well now. If you need an actually picture to see what it is let me know and I can get you one.
As for the knock sensor, that's a different sensor. That's something that basically keeps you motor from blowing do to rod knock. I would change that and also check your timing. If you don't have the knowledge to do this or the tools. I would recommend you have someone that could take care of it.
Hope this helps
