Service engine light is on, had it checked a Advance Auto they said it was the knock sensor. Where is that located and what does it do.

it located on the side of block or cylinder head it detects "spark knock" . the pcm will adjust the timing if spark knock is detected . other words some gas has least octane so if engine is put in strain it will adjust the timing for more power and keep engine from detonation(burnin vavle or piston)
