Sense as a noun means essentially wisdom. Someone with good sense is able to make a good decision. Often it is described as common sense meaning that person has the wisdom that is commonly expected. It makes no sense means that something has no logical basis. Sensation is a much more complex word with multiple meanings. It doesn't have anything to do with wisdom. It has to do with being able to feel. A doctor might poke your leg in an examination and ask do you have any sensation in your legs. Another common meaning of the word is something that is a very big success. Star wars was a sensation when the film was released.

Sensation is generally used for expressing a "feeling", " The disease causes the loss of sensation in the fingerers." I hope it helps,
