Hot pixels are pixels that are always “on”. They show up as a bright pixel instead of representing the colour and brightness that should have been recorded.
The question is, how many hot pixels and how are they grouped? If you only have one or two, that is fairly common and they probably won’t do anything for you. If you have a whole group, together, sensor replacement is the fix.
This post: http://log.bitreview.net/post/990025889/fixing-hot-pixels-on-my-nikon-d90 , says cleaning the sensor a couple of times from the menu in a D90 resolved the problem. This might be the sensor cleaning that shakes the sensor filters, and at the same time the software looks for hot pixels and maps them out… Worth a try, it’s cheap and easy.
