Where is the knock sensor found in a 2000 Nissan Xterra 6 cylinder?
it is underneath the lower intake in the middle of the "valley"
on V6 models. between the cylinder heads on the block. pretty big
job. the knock sensor WILL NOT turn the check engine light on. it
will store a code but NOT turn the light on. (i am a Nissan tech,
trust me) it will effect the timing and fuel strategy though.
