A consensus sequence it the ideal promotor sequence, its never actually found in DNA. It is a sequence of bases downstream of the start site, in E. coli it is found at -35 and -10. It was determined experimentally by comparison of known promoter sequences and selecting the most common bases at each position. Therefore, the closer to the consensus sequence the stronger the promoter will be.
