Can you give directions on how to change it? I don't know where the knock sensor is and so far the only slightly mechanical thing I've done is change a headlight. thanks

my check engine light has been coming on and off - mechanic says it is the knock sensor and a dealership can reset it. Anyone have an idea of what it costs and how long it takes? it is a subaru 2001 legacy sedan with 38K miles ps: do they have to replace the actual part or can the code just be reset to fix the problem? Dealership says it is $180 to replace part and would take 1 1/2 hours, but I was under the impression from the mechanic that it was simpler than this to fix. any advice to help me not get ripped off would be appreciated.
